Medical Equipment Preventive Maintenance: Types, Intervals and Checklists

Types of medical equipment maintenance

The types of medical equipment maintenance are usually described in four groups. Preventive maintenance is scheduled work at set intervals. Corrective maintenance repairs a device after it fails or shows a fault. Predictive or condition-based maintenance uses measurements and monitoring to act when performance drifts. Performance and safety testing, including calibration and electrical-safety checks, verifies that a device meets its specifications.

A sound programme mixes these. Preventive work reduces surprises, corrective work restores service quickly, and testing provides evidence for quality and licensing reviews.

Setting preventive maintenance intervals

Start with the manufacturer's service manual, which defines tasks and recommended intervals for each model. Many manufacturers recommend at least an annual inspection, with additional tasks tied to hours of use, cycles or consumables such as filters, batteries and lamps. Where the manual gives no interval, facilities often set one by risk, usage and history.

A risk-based approach classifies devices by consequence of failure and by how often they are used. Life-support and high-energy devices typically receive tighter schedules than low-risk items. Review intervals every year against actual failure and downtime data. Some authorities allow adjusted programmes for certain equipment if justified; confirm local expectations with your licensing body.

A medical equipment PPM checklist

A medical equipment maintenance checklist should be specific to the device type. A general structure that works across devices is shown below, then refined from the service manual:

• Identification: asset ID, model, serial number, location, date and technician
• Visual inspection: housing, cables, connectors, wheels, brakes, labels
• Cleaning and replacement of consumables: filters, batteries, seals
• Functional test: all controls, displays, alarms and accessories
• Safety test: protective earth, leakage current and insulation as applicable
• Performance check or calibration against reference tools
• Software or firmware version noted and updated where authorised
• Result, defects found, parts used and release to service signed off

Keeping a maintenance log and work orders

A medical equipment maintenance log records every planned and unplanned event against the asset: date, task, findings, parts, time to repair, who performed it and whether the device was released for use. A simple work order template should include the asset ID, request source, priority, description of the fault or task, assigned technician, timestamps and sign-off.

Paper logs work in small facilities, but a computerised maintenance management system makes it easier to schedule, track overdue tasks and report KPIs such as PPM completion rate and mean time to repair. Records also feed asset lifecycle decisions.

Scheduling PPM and sharing the workload

Schedule preventive maintenance around clinical activity. Spread tasks across the year so that the workload is manageable, group visits to the same department, and agree access windows with ward or theatre managers. For theatre-specific guidance see operating theatre equipment maintenance.

Decide which tasks the in-house biomedical engineering team performs and which go to the manufacturer or contractor under a service contract.
