Medical Equipment Maintenance Checklist

A ventilator and an exam light don’t belong on the same maintenance schedule — which is why hospital biomedical engineering departments don’t maintain medical equipment on one calendar, they maintain it by risk. This checklist is organized the way a clinical/biomedical engineering department actually organizes its own inventory: by risk tier, using the same classification model used industry-wide to decide which devices get quarterly attention and which can safely go a year or two between checks.

Risk Classification & PM Assignment

Score each device’s clinical function (1–10), physical risk if it fails (1–5), and maintenance requirement (1–5), then add the three for a total Equipment Management (EM) scoreThis is the Fennigkoh and Smith model — the original, still widely-used framework for classifying medical equipment risk.^[1]
Place any device scoring EM 12 or higher into the mandatory preventive maintenance program; evaluate lower-scoring devices for a reduced strategy
Flag equipment that must stay on the manufacturer’s (OEM) maintenance schedule regardless of EM score: medical lasers, imaging/radiologic equipment, devices subject to federal or state law or CMS Conditions of Participation, and any device without enough service history to support an alternative schedulePer the Joint Commission’s EC.02.04.01.^[2]
For medium- and low-risk equipment not on the OEM-lock exclusion list, evaluate whether it qualifies for Alternative Equipment Maintenance (AEM) based on the facility’s documented risk assessment, not a fixed time-based rule
Document the written justification for any AEM decision — device use, consequences of failure, backup equipment availability, incident history, and maintenance requirements — and get sign-off from the Environment of Care or safety committee
Revert any device from AEM back to its original OEM-recommended schedule if an unexpected failure occurs while it’s on the extended interval

High-Risk / Life-Support Equipment

Default to the full OEM-recommended preventive maintenance and safety inspection schedule for ventilators, anesthesia machines, defibrillators, infusion pumps, and electrosurgical units, given the severity of failure consequences
Test battery backup runtime and alarm function on every device that has one
Perform an electrical safety test — leakage current and ground continuity — consistent with IEC 60601-1
Verify calibration against a traceable reference standard for any device with a calibrated function, such as ventilator volume/pressure or infusion rate accuracy
Confirm and document 100% completion of all scheduled PM on this tier — the Joint Commission does not allow partial credit on high-risk/life-support equipmentPer EC.02.04.03.^[2]
Check for open FDA recalls or safety communications on the specific make and model before returning the device to service

Medium-Risk Equipment

Perform the OEM or AEM-approved preventive maintenance on patient monitors, surgical equipment, and steam sterilizers/autoclaves on scheduleInterval depends on what the device actually does, not EM score alone — a sterilizer and a patient monitor can carry the same EM score and still need very different intervals because of mechanical wear versus electronic stability.^[1]
Run a biological indicator test on every sterilization cycle used for critical or semi-critical instruments — not just on the PM schedule
Verify calibration and functional accuracy on monitors and diagnostic equipment
Inspect and test any backup unit for a function that can’t tolerate downtime
Document the AEM eligibility review on file if this device’s PM interval has been extended beyond the OEM default

Low-Risk Equipment

Perform a basic visual and functional check on exam lights, non-patient-care devices, and non-critical lab equipment on the AEM-approved interval
Confirm the device is still correctly scoped as low-risk — reclassify immediately if its clinical use, location, or failure history changes
Clean and inspect for physical damage, and verify any safety labeling is still legible
Keep run-to-failure items in the same asset inventory as everything else, even with no scheduled PM assigned, so failure history stays visible for future risk re-scoring

Documentation & Compliance

Maintain a single written inventory of all medical equipment, clearly identifying which items are high-risk/life-support
Record, for each device, which maintenance strategy applies — OEM schedule or AEM — and the written criteria used to justify it
Track PM completion against the 100% requirement for high-risk/life-support equipment, and keep non-high-risk completion documented and auditable
Retain inspection, maintenance, and recall-check records in a form ready for a Joint Commission or CMS survey
Log every recall check performed against the specific device record, not just the general model

What Is a Medical Equipment Maintenance Checklist?

A medical equipment maintenance checklist is a documented set of inspection, testing, calibration, and preventive maintenance tasks for the clinical equipment in a hospital or healthcare facility’s inventory — organized not by a single calendar, but by each device’s risk classification. A ventilator and an exam light fail very differently, so they’re maintained on very different schedules.

The standard way to make that classification is the Fennigkoh and Smith Equipment Management (EM) model: each device gets a score for its clinical function, the physical risk to a patient if it fails, and how much maintenance it actually requires. A device scoring 12 or higher goes into the mandatory PM program; lower scores can use a lighter strategy. Two devices can land on the exact same score and still need different intervals, because the score tells you how important the device is — not what specific task it needs or how often.

Risk Tiers at a Glance

High-Risk / Life-Support: Ventilators, anesthesia machines, defibrillators, infusion pumps, electrosurgical units. Defaults to the OEM-recommended schedule; 100% PM completion required.

Medium-Risk: Patient monitors, surgical equipment, sterilizers. OEM or AEM-approved schedule; interval depends on the specific device’s task, not score alone.

Low-Risk: Exam lights, non-patient-care devices, non-critical lab equipment. Can move to a reduced-frequency AEM schedule where the facility’s documented risk assessment supports it.

Excluded from AEM entirely: Medical lasers, imaging/radiologic equipment, devices under federal/state law or CMS Conditions of Participation, and new equipment without enough service history.

Safety Considerations for Medical Equipment Maintenance

Medical equipment maintenance work carries risks beyond the mechanical — a device that’s taken out of service incorrectly, or returned to service without proper verification, can directly affect patient care:

A device pulled for PM is unavailable for patient use. Confirm a backup is in place for anything supporting active patient care before taking the primary device offline.

Electrical safety testing involves live circuits. Only qualified biomedical technicians should perform leakage current and ground continuity testing.

A device returned to service without a completed safety check is a patient safety risk, not just a documentation gap. Treat the sign-off step as mandatory before a device goes back into clinical use.

Sterilizers involve high heat, pressure, and steam. Follow the manufacturer’s lockout procedure before opening or servicing any pressure vessel.

Personal Protective Equipment (PPE)

The right PPE depends on the specific device and task, but most medical equipment maintenance work calls for some combination of the following:

Electrical Safety

Insulated tools and proper lockout/tagout procedures for any testing on live circuits or internal electrical components.

Infection Control

Gloves and, where applicable, gown and mask when servicing equipment that has had patient contact.

Heat/Steam Protection

Heat-resistant gloves and eye protection when servicing sterilizers and autoclaves.

Eye Protection

Safety glasses for any task involving pressurized components, batteries, or cleaning solutions.

Common Medical Equipment Maintenance Mistakes

Treating EM score as the whole answer

Two devices with the same Fennigkoh-Smith score can need very different PM intervals depending on what the device actually does — a sterilizer’s mechanical wear isn’t the same risk profile as a monitor’s electronic stability, even at the same score.

Applying AEM to excluded equipment

Medical lasers, imaging/radiologic equipment, and devices under federal/state law or CMS Conditions of Participation must stay on the OEM schedule — AEM isn’t an option for these regardless of maintenance history.

Letting high-risk completion slip below 100%

The Joint Commission does not allow partial credit on required maintenance for high-risk/life-support equipment — any gap there is a direct survey finding.

Not reverting a device off AEM after an unexpected failure

An AEM-extended interval is conditional on a clean maintenance history — a device that fails unexpectedly while on AEM should go back to the OEM schedule, not stay on the extended one by default.

Frequently Asked Questions

What is a medical equipment maintenance checklist?

It’s a documented set of inspection, testing, calibration, and preventive maintenance tasks for clinical equipment, organized by each device’s risk classification rather than one single calendar — since a ventilator and an exam light carry very different consequences if they fail.

How is medical equipment maintenance risk classified?

The most widely used approach is the Fennigkoh and Smith Equipment Management (EM) model: each device is scored on clinical function (1–10), physical risk if it fails (1–5), and maintenance requirement (1–5). A total score of 12 or higher places the device into the mandatory PM program.

What is Alternative Equipment Maintenance (AEM)?

AEM is a CMS-permitted approach letting hospitals adjust a device’s PM interval or activities away from the manufacturer’s default schedule, backed by a documented facility risk assessment rather than a fixed numeric rule. It doesn’t apply to medical lasers, imaging/radiologic equipment, equipment covered by other federal or state law, or new equipment without enough service history to support an alternative schedule.

Which medical equipment must stay on the manufacturer’s maintenance schedule?

Medical lasers, imaging and radiologic equipment, devices subject to federal or state law or CMS Conditions of Participation, and new equipment without enough service history to support an alternative schedule — these are excluded from AEM regardless of maintenance history.

What does the Joint Commission require for medical equipment maintenance?

Under EC.02.04.01 and EC.02.04.03, hospitals must maintain a written equipment inventory identifying high-risk/life-support items, document the criteria used for any alternative maintenance strategy, and complete 100% of required maintenance on high-risk/life-support equipment, with non-high-risk equipment also inspected, tested, maintained, and documented.

How does a CMMS help with medical equipment maintenance?

A CMMS helps by scheduling PM by risk tier, assigning inspections and calibration work to qualified biomedical staff, and keeping a connected history of completed maintenance, AEM justification, and recall checks for each device. It provides the information and keeps the record — it does not perform the inspection, calibration, or safety testing itself, and it doesn’t assign a device’s risk score; that stays the qualified biomedical engineering team’s job.

How eWorkOrders CMMS Supports Medical Equipment Maintenance

PM Scheduling

Recurring PM schedules can be set per device, by risk tier, so a high-risk ventilator and a low-risk exam light each follow their own interval without drifting.

Work Assignment

Inspections, calibration checks, and corrective work orders can be assigned to qualified biomedical staff, with status tracked through to completion and sign-off.

Asset History

eWorkOrders maintains an asset-based history of completed preventive maintenance and other work performed. Staff record the work through work orders, procedures, checklists, labor, feedback, documents, and related fields. The Asset View includes PMs and Work History, and the Asset History Report lists an asset’s work orders and procedures.

Spare Parts Inventory

Track replacement parts and consumables — batteries, calibration kits, sterilizer components — and link parts used to the specific device and work order.

What eWorkOrders Actually Does for Medical Equipment PM

Classifying a device by risk tier doesn’t help if the resulting PM schedule still drifts in practice. eWorkOrders lets biomedical and facility teams schedule every device’s maintenance by its own risk-based interval, assign it to qualified staff, and keep a connected history of completed PM, AEM documentation, and recall checks for every piece of equipment in the inventory.
