Infusion Pump Preventive Maintenance Checklist
Free infusion pump PM checklist. Flow rate accuracy 1–100 mL/hr, IEC 60601-2-24 calibration, occlusion alarm and NABH steps.
Applicable Standards & Compliance
Pro Tips for Infusion Pump PM
Always include a 1 mL/hr test point during PM — pumps are least accurate below 5 mL/hr, where drug delivery errors have the highest clinical impact
Soak the cassette bay with warm distilled water for 2 minutes before cleaning if heavy crystallisation is present
The anti-free-flow clamp test is frequently skipped but is a direct patient safety risk — always verify the clamp occludes the line when the cassette door is opened
Record battery serial number, installation date and load test result at every PM — this creates traceable history that satisfies NABH inspectors

Infusion Pump Preventive Maintenance Checklist — Inspection Checklist
Common Failure Signs to Watch For
| Warning Sign | Likely Cause | Action Required |
|---|---|---|
| Flow rate inaccurate at low rates (<5 mL/hr) | Cassette drive mechanism wear or contamination | Clean and inspect mechanism; recalibrate; replace if out of spec |
| Occlusion alarm not triggering at expected pressure | Pressure sensor drift or line sensor contamination | Clean sensor; recalibrate occlusion threshold; replace if fault persists |
| Air-in-line alarm activating with clear line | Line sensor contamination or optical path blockage | Clean sensor window with dry lens cloth; replace sensor if alarm continues |
| Battery depletes faster than expected | End-of-battery-life or cell degradation | Load test; replace if runtime <80% of rated capacity |
| Door-open alarm with cassette correctly seated | Latch spring wear or door sensor misalignment | Inspect door latch spring; replace latch assembly if worn |
Maintenance Notes & Sign-Off
Infusion Pump Maintenance Schedule
Daily
3 tasks- Visual inspection — device present, powered and showing ready status
- Self-test pass verification at start of shift
- Battery level confirmation — minimum 80% charge for clinical use
Weekly
4 tasks- Test occlusion alarm function at low and high threshold settings
- Inspect cassette/door mechanism for debris build-up
- Clean line sensor window
- Verify free-flow prevention mechanism engages correctly
Monthly
4 tasks- Full flow rate accuracy test at 1, 10, 50 and 100 mL/hr using pump analyser
- Battery load test — run on battery at 25 mL/hr and time to low-battery alarm
- All alarm tests (occlusion, air-in-line, door-open, end-of-infusion, low battery)
- Electrical safety spot-check
Quarterly
4 tasks- Full IEC 62353 electrical safety test
- Calibration with reference pump analyser at all test flow rates
- Occlusion pressure threshold verification
- Internal component inspection
Half-Yearly
3 tasks- Performance certification to IEC 60601-2-24
- Battery replacement assessment — replace proactively if >3 years old
- Drive mechanism lubrication per OEM schedule
Annual
4 tasks- Full PM certification — issue signed service report with all measured values
- Full IEC 62353 electrical safety report
- Battery replacement if >3 years old regardless of load test
- NABH equipment maintenance record update
Frequently Asked Questions
Per IEC 60601-2-24, infusion pumps must deliver within ±5% at rates ≥5 mL/hr and ±10% at rates below 5 mL/hr. Test at multiple clinically relevant flow rates during PM.
Monthly flow rate accuracy testing and alarm verification, quarterly full electrical safety testing, and annual PM certification per NABH and TJC EC.02.04.01.
Verify that opening the cassette door immediately occludes the IV line via the anti-free-flow clamp, preventing uncontrolled gravity flow to the patient. This is a mandatory safety check.
Replace every 3 years maximum, or sooner if load test shows runtime below 80% of rated capacity. Never rely on the charge indicator alone.
