For healthcare facility administrators, HTM directors, and procurement professionals, choosing a biomedical equipment service provider is never just a simple matter of price per hour. The ramifications of your selection will impact many areas, including clinical uptime, patient safety, budget, and regulatory compliance.

By signing a service agreement, you entrust a vendor with the job of ensuring that vital assets are maintained and documented to meet the exacting requirements of The Joint Commission, CMS, and health departments. Poor decisions frequently become apparent when the stakes are the highest and unexpected inspections take place.

Assuming that you are in the process of evaluating your choices of vendors at the moment, there is a need for a proven approach that will help you see beyond the hype.

Quick Answer!

It is expected of any good biomedical equipment service company that it should be able to provide clear information regarding the equipment it services, the people servicing it, the maintenance services it provides, the repair services it offers, the paperwork it gives, and the things it does not cover under its contract. It is important to evaluate all these things before signing the contract.

What Should You Evaluate Before Signing?

Prior to engaging in a contract for medical equipment maintenance, it is necessary to confirm that the claims made by a vendor through their promotional campaign are consistent with the actual situation. Below are the top 10 points to consider.

1. Equipment and Modality Coverage

First, consider if the firm actually has the capability to support your particular equipment inventory. While many claim to provide “service for all medical equipment,” biomedical maintenance is quite specialized.

You must validate whether your specific make and model is covered by this service provider. Do they deal with only normal biomedical equipment such as infusion pumps and patient monitoring systems or do they also have the expertise needed for diagnostic imaging systems?

The provider should be able to define his serviceable scope not only for new products but also for the existing products that the OEM is no longer supporting. The vendor, who can provide services from the basic clinical devices up to complicated imaging systems such as CT, X-ray, fluoroscopy, C-arm, and ultrasound, will make your vendor management much easier.

2. Technician and Engineering Expertise

The value of the service firm depends on who enters the door. The procurement team has to identify who does the actual work.

Are these technicians officially trained as BMETs or imaging engineers? Do these technicians have hands-on experience with your equipment? The good independent biomedical service company would not hesitate to show you the technical expertise of their people.

If your center depends on special diagnostic equipment, make sure that the vendor has highly skilled engineers on board. It is one thing to replace a broken component, but it takes great experience to troubleshoot an imaging machine failure.

3. Preventive Maintenance Scope

Preventive maintenance (PM) is the essence of any medical equipment service agreement. But “preventive maintenance” could mean anything to any vendor.

It’s imperative that you know precisely what will be included in the agreement. What exactly are the functional tests, calibrations, and electrical safety tests that will be carried out? Are they adhering only to OEM’s recommendations or have they instituted an alternative equipment maintenance (AEM) program?

Additionally, you need to know how your problem will be handled when found during a normal PM inspection. If the instrument fails its calibration, does the fix come as part of the current visit, or does it need another dispatch, estimate, and authorization? The clear understanding of this point avoids any unpleasant surprises.

4. Repair and Corrective-Service Process

The equipment is bound to malfunction one time or another. In the event that it does, how do the repairs take place?

Critique the corrective maintenance SOP of the provider in question in terms of how troubleshooting, repair authorization, and test reevaluation are handled. After the repairs are made, the machine should be reevaluated to see whether it works properly and is safe electrically. Any reliable provider of biomedical services would never allow you to return a repaired medical device to you unless they made sure that it was safe and functional.

5. Documentation and Compliance Support

Healthcare Technology Management: If It Is Not Documented, Then It Did Not Happen. Poor or disorganized documentation is one of the quickest ways to get cited during a facility survey.

Review sample service documentation before entering into any agreement. Effective documentation should contain the following elements:

• Identification of the specific pieces of equipment (make, model, serial number, and asset tag).
• Date of service.
• Description of services performed.
• Inspection and test results (pass/fail criteria).
• Actions taken.
• Technician that serviced the equipment.

Your records should be organized, readily available to your facility’s personnel, and able to be quickly produced when an inspector or surveyor arrives.

6. Response Time and Service Availability

In cases where critical equipment breaks down, each hour affects both patients and bottom lines. However, when the vendor guarantees “fast response time,” it is important to understand their definition of “response time.”

Is “response time” equal to the time taken to respond to a phone call, the time it takes to dispatch a repair person, or the time it takes to reach the site? In addition to this, one must define the definitions of telephone response and onsite response and resolve expectations. Finally, understand whether the contract provides for emergency or after-hour services.

7. Service Contract Terms

It is here that the procurement manager must scrutinize things. The terms and conditions of a medical equipment service agreement will determine your financial exposure. Look at the exclusions as closely as you do the inclusions.

In scrutinizing the terms and conditions, make sure that you have a clear understanding of the following:

• Labor and Travel: Are travel expenses included in the deal, or charged separately for each trip?
• Parts: Are replacement parts covered up to a specified dollar value, or are all parts outside of the contract?
• Exclusions: Are consumables such as batteries, cables, patient leads, etc., not covered? (They usually aren’t, but you should be aware.)
• Contract Term and Termination: What is the term of the contract? How much notice must be provided for termination of the contract? Watch out for contracts that renew themselves aggressively and force you to accept substantial annual rate hikes without approval.

8. Parts and Repair Transparency

One of the main reasons why equipment becomes unavailable is related to the accessibility of parts. It is very important to understand what sort of parts they provide for repairs. Do they work with OEM parts, high-quality aftermarket parts or refinished parts? What is their attitude toward back orders and discontinued parts? The reliable vendor should always discuss part procurement with you and never make any surprise repairs without your permission.

9. Geographic Coverage

The physical location of a service provider and their geographical presence are very important. While a large corporation that operates nationwide may seem very strong and reputable on paper, having your closest technician three states away will not help.

For healthcare facilities located in Illinois or the surrounding areas, the use of a Midwest-based company implies that the technicians would be physically closer to them. The local and regional companies have easier logistics for travel, as well as greater flexibility of scheduling visits due to the increased chance of meeting the same technicians.

10. References and Track Record

Finally, never sign a biomedical equipment maintenance contract without checking references.

Do not rely on any generic quote available online to prove that the supplier is qualified. Always ask the company to provide references of facilities similar to yours in terms of size, capacity, and equipment. For instance, if you run an ambulatory surgical center, talking to a reference at a hospital will not necessarily help you understand how they meet your facility’s requirements.

OEM vs. Independent Service Provider: Which is Better?

The decision about whether to use OEM or ISO service is one of the most frequent choices facility managers must make.

An OEM service is usually required when dealing with brand new and highly proprietary equipment that is still covered by its warranty. The company knows its products very well and is immediately accessible for any software updates. But at the same time, the contract with OEM is the most costly one, and it services only its own brand of equipment.

The ISO provides a multi-vendor solution. An ISO can handle maintenance and repair work for equipment from different vendors using the same service provider. This helps in cutting down on administrative costs. Also, independent service companies are always more economical than other service companies. They can offer service schedules based on your facility’s requirements.

It all boils down to how old your equipment is, the condition of its warranty and the expertise of your in-house team. What most hospitals do is a combination approach, where they have new and complex systems under OEM and move their clinical and old imaging equipment to an independent company.

15 Questions to Ask Before Signing

Use this checklist during your vendor evaluation process:

1. Which equipment categories and specific models do you service?
2. Who will actually perform the service on-site?
3. What specific training or experience does that technician have with our equipment?
4. What preventive maintenance activities (calibration, safety testing) are included?
5. What testing and documentation will we receive after a visit?
6. How are urgent or emergency service requests handled?
7. How is your response time measured (phone vs. on-site)?
8. Which parts and repair costs are included in the base contract?
9. What is strictly excluded from the contract?
10. What happens when equipment cannot be economically repaired?
11. Are technician travel charges included or billed separately?
12. How are additional, out-of-scope repairs approved and billed?
13. How are service records stored, and how quickly can we access them?
14. What happens when the contract term ends and renews?
15. How can either party terminate the agreement, and what notice is required?

Red Flags to Watch For

During your vendor review, be on the lookout for warning signs that indicate a poor fit:

• Vague Coverage of Equipment: If they say “we do it all” without requesting an asset list, they certainly do not grasp the complexities of your equipment.
• Vague Contractual Exclusions: If a contract does not specify the exclusions, you can definitely expect trouble on billings in the future.
• Poor Record Keeping: If they cannot provide a sample report for PM inspection instantly, their record-keeping practices are surely not up to mark.
• Undisclosed Subcontracting: If they consistently subcontract work to external companies without informing you, you have no control over who gets access to your facility.
• Automatic Contract Renewal with Pressure: Be wary of contracts with automatic renewal clauses, which involve a massive increase in prices if they are not canceled within 90+ days.

Frequently Asked Questions

Does an independent biomedical equipment service company serve healthcare facilities in Illinois?

Yes. The independent biomedical companies such as Midwest Biomedical Technologies cover the whole Chicagoland region and the rest of Illinois. Our technicians visit the hospitals, clinics and other healthcare establishments and provide them with on-site services for preventive maintenance and repair needs.

What should Illinois healthcare facilities ask before signing a biomedical service contract?

It is important that facilities inquire on how service records will be maintained in order to comply with the regulations set out by the state health department and CMS. Facilities also need to clearly inquire about inclusion versus exclusion of travel expenses, replacement parts, and after-hours services.

Can a Midwest biomedical service company support imaging equipment?

Of course, though it all depends on the particular engineering abilities of the provider. Midwest Biomedical Technologies can offer great help in imaging equipment because of over 30 years of specialization in CT, X-rays, fluoroscopy, ultrasound, and C-arms.

How should a healthcare facility compare OEM and independent equipment service?

Compare them based on flexibility, costs, and age of equipment. OEMs are the best choice when you have a completely new proprietary system that is still under warranty. Independent companies provide more flexibility and can repair equipment from different manufacturers under one agreement.

What documentation should a biomedical equipment service provider provide?

The provider should provide complete service reports, including the identification of the equipment (make/model/serial number), date of service, activities completed during service, test results, and recommendations for future corrections.

A strong biomedical maintenance program contains six elements: a complete equipment inventory, risk-based preventive maintenance tasks, electrical safety testing, calibration verification, a repair and recall workflow, and audit-ready documentation held in one maintenance management system. Facilities worldwide spent an estimated $45.07 billion on medical equipment maintenance in 2025, according to The Business Research Company.

Most facilities already do some of this work. The gap is usually structure: tasks happen, but the records sit in different places, intervals drift, and nobody can prove what happened when a surveyor asks. The sections below walk through each element and the evidence it should produce.

Six Core Elements of a Strong Biomedical Maintenance Program

The core elements of a biomedical maintenance program are an equipment inventory, a scheduled set of preventive maintenance tasks, electrical safety testing, calibration verification, a repair and recall workflow, and centralized documentation. Remove any one of them and the program stops being provable.

Each element exists to produce evidence. The inventory proves you know what you own. PM records prove devices received service on schedule. Test values prove equipment is safe and accurate. Work orders prove someone corrected failures before a device went back into patient use.

That evidence chain separates a real program from a pile of service calls. The table below maps each element to the record it should generate and to the gap that appears during a state survey, CMS inspection, or Joint Commission review when the element is missing.

Program element	The record it produces	The gap a surveyor finds without it
Equipment inventory	A current asset list with device ID, location, and risk class	Devices in active use that appear on no list
Preventive maintenance schedule	Completed PM checklists with dates, results, and technician sign-off	Overdue or undocumented PM on patient-connected devices
Electrical safety testing	Recorded leakage current and ground resistance values	A pass sticker with no test values behind it
Calibration verification	Measured readings compared against tolerance limits	Devices drifting out of spec with no evidence anyone checked
Repair and recall workflow	Work orders, corrective actions, and recall responses	Failed equipment returned to service with no record
Documentation system	One retrievable service history per device	Records scattered across binders, inboxes, and vendor portals

If any entry in that middle column does not exist at your facility, that row is where the work starts.

The Case for Biomedical Maintenance Services

Facilities invest in biomedical maintenance services because equipment failures put patients at risk, interrupt care, and generate citations that cost far more than the maintenance would have. ECRI’s Top 10 Health Technology Hazards report for 2026, published in January 2026, flags substandard medical products and missed device recalls among the year’s most serious patient-safety threats, and both get caught at the facility level by the same mechanisms a maintenance program provides: inspection, testing, and organized records.

The operational case is just as direct. A vital signs monitor that drifts out of tolerance produces bad readings long before it produces an error message. Scheduled service catches that problem quietly on a planned visit instead of loudly in the middle of a shift.

The compliance case is the bluntest of the three. Surveyors from CMS, state licensing agencies, and the Joint Commission do not accept a verbal assurance that equipment gets maintained. They ask for the records, and a facility either has them or it does not.

Preventive Maintenance Tasks That Belong on Every Schedule

Every schedule of preventive maintenance tasks should include visual inspection, cleaning of serviceable components, functional testing against intended clinical use, battery checks, replacement of manufacturer-specified wear parts, and verification that alarms and safety features work. Measured values belong on the checklist wherever the device allows them, because a recorded reading carries more weight with a surveyor than a checked box.

Service intervals start with the manufacturer’s recommendation. From there, risk classification, usage intensity, and operating environment adjust the frequency: annual PM is a common baseline for patient-connected devices, while high-risk and life-support equipment takes priority and often needs semiannual or quarterly attention. Where regulations permit an alternative equipment maintenance strategy, the interval change must rest on documented history, not convenience.

Imaging systems deserve their own line in the schedule. A CT scanner or X-ray unit can produce degraded output without any visible malfunction, so its PM depends on system-specific performance parameters rather than a generic checklist. Structured preventive maintenance programs set those frequencies by equipment category during the initial inventory review, then hold them.

Maintenance Management Systems Hold It All Together

Maintenance management systems hold a program together by keeping the inventory, the service schedule, and every completed record in one place that staff and surveyors can search and surveyors can verify. A working system tracks each device’s ID, location, and risk class, its PM due dates, its test results, its repair history, and its recall status.

The format matters less than the discipline. A hospital typically runs CMMS software; a small clinic can run a rigorously kept shared log. Either version succeeds on the same three tests: every device has one retrievable history, overdue PM is visible before a surveyor finds it, and no record lives only in one technician’s inbox.

The system also depends on what enters it. A service visit that ends without written findings never happened as far as an inspection is concerned, which is why documentation and reporting support belong inside the service relationship itself, delivered after every visit rather than reconstructed before every survey.

Repairs, Parts, and Recalls: Closing the Loop

A program should handle repairs through documented work orders, verify performance before any device returns to patient use, and check every manufacturer recall against the equipment inventory. The repair record needs five parts: the reported symptom, the diagnosed cause, the corrective action, the post-repair verification, and the sign-off.

Recall tracking is the piece facilities most often skip, and the scale of recall activity makes that a real exposure: the FDA oversaw recalls of 3,934 medical devices between fiscal years 2020 and 2024, according to a U.S. Government Accountability Office report published in December 2025. Without a current inventory, a facility cannot even confirm whether a recalled model sits in its building.

Parts belong in the plan too. Stocking the wear items that fail most often, or working with a provider who does, shortens downtime on the equipment categories a facility depends on daily. When a fault does surface, organized repair support closes the loop with written findings instead of an invoice and a shrug.

How Midwest Biomedical Technologies Structures a Program

MBT builds a maintenance program by starting with an equipment inventory review, setting service frequencies by category, and delivering written documentation after every visit. The company is an independent biomedical service organization established in 2018, based in Oak Brook, Illinois, and serving nursing homes, clinics, ambulatory surgery centers, imaging centers, hospitals, and assisted living communities across Illinois and the broader Midwest.

Programs can fold electrical safety testing and calibration and performance verification into the same recurring agreement, so one schedule and one documentation trail cover the full scope. Records arrive structured for Joint Commission surveys, CMS inspections, and state licensing reviews, and facilities work directly with the team that performs the service rather than a dispatch queue.

Imaging is the standout capability. MBT’s lead engineer has spent more than 30 years working exclusively on radiology and diagnostic imaging equipment, including CT, X-ray, fluoroscopy, C-arm, and ultrasound systems, which is a depth of specialization few independent providers carry. The company also states its limits plainly: if a device falls outside its scope, the facility hears that before any agreement, not after.

Frequently Asked Questions

The questions facility teams ask most often cover service frequency, the preventive-versus-corrective distinction, requirements for small sites, survey documentation, and outsourcing. The answers below address each one directly.

How often should biomedical equipment be serviced?

Service frequency follows the manufacturer’s recommended interval, adjusted for risk classification, usage intensity, and operating environment. Annual preventive maintenance is a common baseline for patient-connected devices, while high-risk and heavily used equipment often needs semiannual or quarterly visits. An alternative equipment maintenance strategy may change intervals where regulations permit and service history supports it.

What is the difference between preventive and corrective maintenance?

Preventive maintenance is scheduled work a technician performs before failure: inspection, testing, part replacement, and verification on a set interval. Corrective maintenance is an unscheduled repair after a fault appears. A strong program plans the first and documents both, because a repair without a recorded post-repair check leaves an unverified device in patient use.

Do small clinics and nursing homes need a formal maintenance program?

Yes. State licensing reviews and CMS requirements apply to small facilities, not just hospitals, and surveyors expect documented service records for patient-care equipment. A small site’s program can stay simple: a current inventory, a written schedule, and a completed record for every visit. Facility size changes the scale of the program, never the need for one.

What records do surveyors ask for during an inspection?

Surveyors typically ask for the equipment inventory, completed preventive maintenance records with dates and results, electrical safety test values, calibration evidence for applicable devices, and repair histories showing corrective actions. They want measured values and signatures rather than blank checkboxes, and they expect records retrievable during the visit, not reconstructed after it.

Can a facility outsource its entire biomedical maintenance program?

Yes. Facilities without in-house biomedical staff commonly contract the full program to an independent service organization, which manages the inventory, schedule, testing, and documentation under one agreement. Larger facilities often split coverage, keeping routine work in-house while outsourcing specialized categories such as imaging. Either model works when one party clearly owns the records.

Where to Start

Start by listing every device in the building, because the inventory decides everything downstream: what gets scheduled, what gets tested, and what records must exist. Then compare that list against your current service files; every device with no history is a gap, and the gaps are the plan.

You do not have to run that review alone. MBT will walk your inventory with you, recommend service frequencies by category, and structure a program around your equipment and your compliance requirements. Get started or call (708) 406-9887.

When medical equipment fails in a hospital, patients are at risk. A delay in diagnosis and treatment causes suffering while revenues are lost due to the inability to provide services. What should hospitals know before requesting service for their ultrasound and x-ray equipment?

Before attempting any repairs, the hospital administration should check whether the equipment is under warranty, whether there are certified parts available on the market, and whether the service provider is FDA- and Joint Commission-certified. The administration should also establish if the cause of the malfunction was hardware- or software-related or due to the operator’s error, which might indicate whether a minor adjustment or a major overhaul is necessary.

At Midwest Biomedical Technologies, we often advise clinical engineering teams on precisely these sorts of issues. Whether you run a major regional medical center in Chicago or a small outpatient surgery clinic, understanding the technical and regulatory implications of your diagnostic imaging equipment is vital.

Consider these factors before approving any service calls on your high-value diagnostic imaging equipment.

The Financial and Clinical Impact of Equipment Downtime

Medical imaging equipment is one of the most substantial capital expenditures for any medical facility. The downtime of a CT scanner, MRI machine, or digital radiography room has serious financial repercussions. Reduced patient capacity, delays in diagnostic procedures, and the diversion of ambulatory and emergency traffic to other facilities can cause significant disruption to hospital operations.

For routine diagnostics, long equipment downtime causes rescheduling that frustrates patients and harms a hospital’s reputation. In addition, an x-ray or ultrasound room that’s down for repairs is a huge expense, with thousands of dollars in lost revenue every day. This is why hospitals need proactive Healthcare Technology Management (HTM) and quick, reliable biomedical equipment repair.

Key Considerations Before Servicing Ultrasound Equipment

Ultrasound machines are exceptionally portable and delicate, which makes them subject to a unique set of potential damages. Before agreeing to pay for an ultrasound equipment repair, make sure you review the following list of common failure modes.

1. Transducer and Probe Integrity

The most common source of failure in an ultrasound machine is the transducer probe. They get dropped, run over, dropped again, and subjected to harsh chemical cleaners. First, try a different probe in the same port to rule out the probe itself. Then, test the suspected faulty probe in another machine if possible. Our techs often see hospitals throw away thousands of dollars in equipment because one specific crystal array or pin needed repair.

2. Software and PACS Integration

Sometimes, a machine can be working fine mechanically, but it may not be sending images to the PACS or RIS. Before calling in mechanical service, check the network connections and DICOM setups. Sometimes it may just be a simple software update or an IP conflict that is causing the error.

3. Power Supply and PCB Issues

Ultrasound units require a certain amount of electricity. Deviations from the standard can damage the printed circuit boards or the power supply. If your system is shutting down or freezing randomly, test the facility’s power supply and the unit’s power supply to rule out those problems before you suspect the hard drive or mother board.

What to Know Before Executing X-Ray Equipment Repair

X-ray equipment repair involves high voltages, large moving parts and many safety precautions to avoid radiation exposure. The challenge is greater in terms of regulatory requirements and patient safety.

1. X-Ray Tube Lifespan and Calibration

The x-ray tube is a consumable item. It loses its performance each second because it is used. If you have noticed poor-quality imaging or arcing, it is a sign that the tube is going bad. But before you replace the x-ray tube, which is very expensive, check if the generator and the high-voltage cables are operating properly. A defective cable can mimic the symptoms of a bad x-ray tube.

2. Collimator and Table Alignment

Mechanical breakdown of the bucky, table, or collimator can cause misalignment. When technologists have difficulty placing a patient or the radiation field does not match the light field, the machine requires mechanical calibration. Mechanical calibration should only be performed by qualified personnel to ensure that it meets FDA radiological health regulations.

3. Radiation Safety and Compliance

Any service performed on an x-ray tube, collimator or generator must be calibrated to verify that exposure levels are within the required limits. The Joint Commission then requires documentation of these repairs. Your imaging service provider should be able to provide service reports verifying that the equipment was tested and calibrated to original equipment manufacturer (OEM) specifications before being returned to service.

Repair vs. Replace: A Decision-Making Framework

One of the most challenging decisions that hospital administrators are confronted with is the decision to invest in new equipment. Our experts offer the following guidance on conducting the research for the procurement of a new radiology system.

Decision Factor	Lean Toward Repair	Lean Toward Replacement
Equipment Age	Under 7 years old	Over 7–10 years (End of Life)
Cost of Repair	Less than 30-40% of replacement cost	Greater than 50% of replacement cost
Parts Availability	OEM or aftermarket parts readily available	End of Support; parts are obsolete or hard to source
Clinical Utility	Meets all current diagnostic standards	Lacks modern integration (e.g., poor DICOM support, low resolution)
Failure Frequency	Isolated, rare failure	Chronic breakdowns causing frequent patient delays

If an old digital radiography system that requires a new digital detector panel and a new tube changes at the same time during the year, it is usually more cost-effective to purchase a new system. On the other hand, a five-year-old ultrasound with a broken monitor should virtually always be repaired.

Choosing the Right Service Provider

When a piece of equipment breaks down, companies typically have three options regarding repairs: the OEM (Original Equipment Manufacturer), internal resources such as clinical engineering, and independent service organizations (ISOs).

Although OEMs often have extensive knowledge about their equipment, their service contracts can be expensive, and they sometimes have long response times. Meanwhile, in-house service can provide a first line of defense but may lack the tools or specialized knowledge to perform advanced diagnostic tests or access particular calibration software.

Partnering with an experienced ISO is usually the best option in terms of fast response, broad multi vendor expertise and cost effectiveness. If you are looking for the right partner, make sure to check our guide on how to choose the right medical equipment repair service for your facility.

Common Mistakes Hospitals Make During Equipment Maintenance

Through our practice in servicing medical facilities, we have noted several recurring issues that lead to losses for a hospital.

1. Ignoring Preventive Maintenance (PM): The biggest waste in terms of both time and money is treating equipment breakdowns as the primary issue. Only servicing machines once they break down leads to a much shorter lifespan for machinery and electronics.
2. Poor Error Code Documentation: Whenever a machine goes faulty, it usually shows an error code on the screen. However, technicians quite often clean the system, restart, and move on without writing down what the code was. Always document the code to save hours of troubleshooting later.
3. Using Improper Cleaning Agents: Some machines, such as ultrasound’s screen or transducer cable, require special treatment when cleaning. Using bleach wipes that are not designed for medical equipment will damage the plastics and rubbers, shortening the device’s lifespan.
4. Neglecting to Backup Presets and Settings: Before allowing a service center to replace a major part like the motherboard, make sure you backup all your custom software settings, network configurations, and presets. Otherwise, your radiology department staff may have to spend hours, days, or even weeks re-establishing the devices’ settings.

Preventive Maintenance Checklist for Imaging Systems

To ensure the equipment’s greatest possible uptime, it is essential to design and stage a particular preventive maintenance workflow. Although the requirements may differ for different manufacturers, the following general instruction is based on the standard established by the Association for the Advancement of Medical Instrumentation (AAMI).

Daily Tasks (Completed by Technologists)

• Inspect all relevant transducer cables, x-ray table tracks, and power cords for physical damage.
• Make sure that the connections to PACS and RIS have been established.
• Wipe all patient-contact surfaces with approved disinfectants.
• Ensure all physical buttons and touchscreen areas are functioning properly.

Monthly Tasks (Completed by In-House Biomed or Technologists)

• Inspect and clean the air filters of computer towers and other relevant machines to prevent overheating
• Conduct phantom tests on ultrasounds and CT/x-ray machines to ensure there are no issues with images being produced
• Test the monitor stands, brakes and wheel locks for mechanical integrity.

Annual/Semi-Annual Tasks (Completed by Certified Service Providers)

• Perform a full electrical safety test.
• Check radiation output and adjust the x-ray generator.
• Perform an internal software diagnostic and clean hard drive cache.
• Install any OEM software patches or updates.

To Conclude

The proactive approach to management of the medical imaging equipment is of paramount importance. This includes knowledge about the vulnerabilities of particular machines (such as ultrasound or x-ray equipment), adherence to relevant rules and regulations and taking into due consideration the timing of repairs or replacements of the devices.

Never wait until you’ve had a catastrophe. See that your preventive maintenance schedule is always adhered to and that you have a reputable service partner on call whenever a crisis erupts.

Frequently Asked Questions (FAQs)

How long does it typically take to repair an ultrasound machine?

Most ultrasound equipment repair can be done within 24-48 hours depending on the availability of a particular probe or circuit board. Software issues or calibration of the machine can be fixed within a few hours.

Are aftermarket parts safe for medical imaging equipment?

Yes, if they are certified and tested to be equal to or better than OEM standards. Reputable service providers will use high-quality aftermarket or refurbished parts to save you money while still meeting FDA and Joint Commission regulations.

What is the average lifespan of an x-ray tube?

An x-ray tube generally lasts from four to seven years depending on the number of patients and the types of tests. Warm-up practices and regular maintenance usually prolong tubes’ lives.

How often should medical imaging equipment undergo preventive maintenance?

Most manufacturers and even regulatory agencies such as the Joint Commission recommend comprehensive preventive maintenance at least once or twice a year. However, high-use facilities may need to perform them more frequently, such as quarterly, to ensure that equipment is available when needed.

Why is my ultrasound machine not connecting to PACS?

Network connection problems are commonly caused by IP address conflicts, firewall updates on the hospital’s main server, or a corrupted DICOM configuration on your machine. Therefore, check your cables and contact your IT department before calling for a hardware technician.

Can in-house biomedical teams repair digital radiography systems?

In-house personnel can perform minor diagnostic tests and repairs such as physical inspections and replacing parts. More involved procedures such as servicing high-voltage generators or performing radiation calibrations necessitate the use of specialized equipment and should be left to qualified imaging personnel.

Walk into any healthcare facility and ask when they last serviced their medical devices; you are likely to hear the answer, “We do that every year.” In any healthcare facility, performing a service on equipment every twelve months is normal. As such, the idea of having an annual service schedule is so deeply rooted in the minds of facility managers that they believe it to be a legal requirement.

But is it?

The short answer is no. There is no one-size-fits-all medical device calibration schedule. An annual service may be a good default, but a rigid policy of servicing everything every year can lead to over-calibrating simpler, lower-risk devices while potentially overlooking more complex, higher-risk equipment.

At Midwest Biomedical Technologies, our experienced team has been assisting medical institutions with establishing compliant equipment management programs within the Midwest region since 2018. In this guide, we have discussed the factors that dictate medical equipment calibration frequency, established the criteria for assessing inventory, and outlined the relevant regulatory compliance standards.

How Often Should Medical Equipment Be Calibrated?

Medical equipment must be calibrated in accordance with the manufacturer’s recommendations and the clinical risk associated with the device. Even though most manufacturers suggest a yearly calibration, the calibration intervals should be determined based on the equipment’s usage and the environment in which it is kept.

Instead of relying on a generic timeline, healthcare facilities should determine their calibration interval by evaluating:

• Original Equipment Manufacturer (OEM) recommendations
• Applicable federal, state, and accreditation requirements
• The device’s intended clinical use and patient risk
• Measurement accuracy requirements and historical drift
• Frequency of use and environmental wear

What Determines the Right Calibration Interval?

Establishing the calibration interval requires a risk-based approach. According to the National Institute of Standards and Technology (NIST), there is no standard calibration interval because numerous factors should be considered before establishing the calibration interval of an instrument.

Manufacturer Recommendations

The primary consideration for any service schedule can be found in the manufacturer’s service manual. For many categories of equipment, particularly imaging and radiologic devices, federal regulations and accreditation agencies require adherence to the OEM maintenance schedule.

Equipment Risk and Clinical Impact

A device that is used in a critically important procedure or one in which a dosage must be precise to exact measurements poses a greater risk if its reading is inaccurate. High-risk equipment needs to be calibrated more often or more strictly than lower-risk or general equipment.

Usage Frequency and Environment

A patient monitor that is located in a busy emergency room will see more wear and tear as well as use its sensors more frequently than the same device in a less active outpatient setting. The differences in physical, thermal, and mechanical forces can make a significant difference on the lifespan of a piece of equipment

Equipment Age and Historical Drift

As equipment ages, it tends to deviate from the precision of its original state at a quicker pace. By analyzing the equipment history and calibration records, you can determine if a particular piece of aging equipment requires a shortened maintenance schedule to stay within tolerance.

Regulatory and Accreditation Requirements

Joint Commission Organizations as well as CMS permit facilities to make alterations to the maintenance schedules of particular devices through the use of alternate equipment management or AEM. This applies to a variety of devices, but with specific exceptions and with specific requirements to understand what devices require the OEM timeline.

Should All Medical Equipment Be Calibrated on the Same Schedule?

No. Assigning the same service schedule to all of an organization’s devices is not a cost-effective or clinically responsible approach to equipment management. A proper inventory management program will classify devices according to their individual needs and assign service schedules accordingly.

Equipment Situation	Factors Affecting Frequency	What the Facility Should Consider
Frequently used equipment	High physical wear, sensor degradation, rapid historical drift.	Review performance history and usage rates. Consider shortening the interval if out-of-tolerance results occur frequently.
High-risk equipment	Severe clinical consequences of inaccurate readings or failure.	Strictly follow applicable requirements and manufacturer guidance. Do not extend intervals without robust, documented justification.
Imaging equipment	Strict manufacturer specifications, radiation safety, complex internal components.	Use documented service and verification procedures. CMS guidelines generally prohibit AEM programs for imaging equipment.
Newly acquired equipment	Limited historical data regarding stability in your specific facility.	Start strictly with manufacturer guidance. Build an equipment history before considering any schedule adjustments.
Equipment after repair	Corrective work, replaced components, or physical trauma may affect measurement baseline.	Perform appropriate post-repair testing and calibration verification before returning the unit to clinical use.
Equipment with repeated failures	Evidence of mechanical instability or rapid electronic drift.	Evaluate if the equipment has reached its end of life or if the calibration interval needs to be significantly shortened.

What Is the Difference Between Calibration, Preventive Maintenance, and Performance Verification?

These terms are often used interchangeably in the context of busy hospitals and clinics, but they have significantly different implications for the biomedical field. Being able to distinguish the two is essential to correctly servicing and recording service completion for compliance purposes.

• Calibration: It can be described as the process of comparing a device’s measurement to a traceable reference standard (i.e., NIST-traceable standards) and adjusting the device so that its measurements are accurate in relation to the standard.
• Performance Verification: It is the process of testing the equipment against set standards to confirm that it is performing within the set parameters without making adjustments to it.
• Preventive Maintenance (PM): A scheduled inspection, cleaning, lubrication, or servicing of equipment or a replacement of batteries or parts in anticipation of future failure and to ensure continued reliability.
• Repair: Actions taken to restore an item that is inoperative, malfunctioning, or nonconforming to technical specifications.

Typically, our biomedical calibration services comprise all three of these steps: we do preventive maintenance, check if everything is working fine, and then calibrate the sensors to guarantee total accuracy.

When Should Medical Equipment Be Checked Before Its Scheduled Calibration?

Even if your equipment has a 12-month service schedule, there are some events that require immediate intervention. Do not wait for the next preventive maintenance if the device went through:

• Physical damage: The device was dropped, hit, or exposed to liquid spills.
• Major repairs: Replacing any of the device’s major internal components (such as sensors, power supplies, or motherboards).
• Unusual readings: Practitioners claim that the results are abnormal for the patient’s condition.
• Relocation: Very sensitive equipment was transported to another facility or subjected to extreme temperatures during transit.
• Repeated alarms: The machine tends to give technical errors or warnings.

How Often Should Imaging Equipment Be Calibrated?

Imaging equipment is one of the most hazardous and highly regulated forms of medical devices. Diagnostic X-ray, computed tomography, fluoroscopy, and ultrasound procedures require proper installation and commissioning to achieve dose accuracy and image quality.

Unlike some general biomedical devices, the maintenance schedule for most imaging equipment cannot be determined by a facility’s preferences. Facilities usually follow the recommendations of the original equipment manufacturer (OEM), state regulations regarding radiation safety, and federal regulations.

At Midwest Biomedical Technologies, imaging is our specialty. Our staff engineer has more than 30 years of experience in radiology and diagnostic imaging. From our office in Oak Brook, Illinois, we provide service imaging equipment support in the region, making sure that your equipment receives the service and testing needed to meet manufacturer guidelines.

What About C-Arm Equipment?

Mobile c-arms are used extensively in the operating room, outpatient surgical centers, and the pain management environment. They undergo frequent movement, being wheeled through doorways and exposed to temperature variations in the OR environment. All this requires careful oversight.

C-arm maintenance comprises more than simply a basic electrical safety inspection. It usually includes a performance evaluation of the image intensifier or flat panel detector, dose checks, mechanical examination, and comprehensive preventive maintenance of the device’s cooling and power supply.

If a system sustains damage, it may require professional C-arm repair. However, testing after repair is a critical step because even a minor maintenance activity can compromise the system’s geometry or output. Thus, facilities should always make sure that systems undergo a comprehensive performance evaluation before being returned to the operating room.

How Should Healthcare Facilities Track Calibration?

If it’s not documented, it didn’t happen. Documentation allows the facility to stay on top of what is going on with their equipment and get ready for state surveys, joint commissions, and internal audits.

A compliant calibration record should capture:

• Equipment identification (Name, OEM, Model, exact Serial Number)
• The particular workshop or department where it was serviced
• The date when it was serviced
• The one who performed the service (name and signature of technician/service provider)
• The test equipment used (including its calibration traceability)
• Particular test results (“as found” and “as left”), pass/fail
• Out-of-tolerance findings with corrective action taken
• The next due date for servicing.

Keeping up with this documentation is a huge task for a busy medical office or rehabilitation facility. That is why many Midwest facilities turn to us for documentation and compliance support to help maintain their equipment histories in an organized and auditable manner.

What Happens If Equipment Fails Calibration?

When a medical device is calibrated or tested and found to be outside of acceptable tolerances, the facility needs to respond accordingly. The general process would be as follows:

1. Remove from service: Take the equipment off the clinical floor and put it out of service tag to ensure that it is not used until repairs have been made.
2. Documenting the failure: It is important to document the “as found” readings that will give you information on what caused the incident.
3. Assessment of impact on patient care: If the device was out of calibration, clinical leadership might have to take actions to determine if patient care had been compromised.
4. Perform corrective action: The biomedical technician attempts to adjust the device back into specification. If the first action proves ineffective, medical equipment repair and/or replacement of components are required.
5. Verify performance: The repaired unit must be calibrated to verify that it is working correctly.
6. Document the return: The final “as left” status is recorded, and the equipment is returned to service.

How Can a Facility Build a Practical Calibration Program?

Building an effective equipment management program means changing the paradigm from a reactive paradigm to a proactive paradigm. 

Therefore, the first step is to create a complete digital inventory of the existing equipment: The proverbial knowing what you own. Then, a schedule should be created for every piece of equipment according to the manufacturer’s recommendations or legal requirements.

For many medical offices, skilled nursing facilities, and outpatient clinics, managing this kind of schedule internally can be overwhelming; but partnering with an independent service organization to administer a comprehensive preventative maintenance program is simple!

Frequently Asked Questions

How often should medical equipment be calibrated?

Medical equipment should be calibrated according to the manufacturer’s recommendations, amount of use, and the clinical risk it presents. Typically, equipment is calibrated once a year, but some equipment carries a higher or lower risk or is used more or less frequently, and so is calibrated more often or less often accordingly.

Is annual calibration required for all medical equipment?

No, not all equipment is calibrated annually. That’s a federal standard baseline, but every piece of equipment has a calibration schedule defined by the OEM (Original Equipment Manufacturer), federal regulations, or equipment history. Some are done semi-annually, while others are less frequent.

What determines a medical equipment calibration interval?

The calibration schedule is based on the information retrieved from the manufacturer’s service manual, clinical risk, frequency of use, potential hazards, the instrument’s maintenance history, and relevant regulatory or accreditation requirements (CMS/JCAHO).

Does medical equipment need calibration after repair?

Yes, any device that has been repaired by major corrective maintenance or has undergone component replacement or has suffered trauma shall be verified for performance and accuracy through testing and calibration. This is to ensure that repair did not affect the measurement baseline of the device before returning it to service.

Does Midwest Biomedical Technologies provide calibration services in Illinois and other Midwest states?

Yes. Based in Oak Brook, Illinois, Midwest Biomedical Technologies offers biomedical calibration, preventive maintenance, and repair services to medical institutions in the Midwest of the U.S., including Illinois, Indiana, Wisconsin, Michigan, Iowa, and the surrounding states.
