What This Guide Helps With
Identifies causes of false bed exit alarms, including sensor misalignment, mattress positioning, patient movement, and electrical interference.
Step-by-Step Troubleshooting
Ensure Patient Safety
- Confirm the patient is safely supported or transferred to another bed before testing alarms. Patient safety takes priority over troubleshooting.
Check Mattress and Sensor Placement
- Ensure the mattress is properly seated and aligned. Verify that bed exit sensors or pressure mats are correctly positioned and free from folds or obstructions. Misalignment often triggers false alarms.
Inspect Bed Side Rails and Accessories
- Confirm side rails are fully up or down as intended, and remove or adjust any accessories (blankets, cushions, overlays) that may activate sensors.
Verify Sensor Connections
- Check all cables from the bed exit sensors to the control panel. Ensure connectors are seated firmly and undamaged. Loose or damaged connections can create intermittent alarms.
Check Control Panel Settings
- Review alarm sensitivity settings on the bed control panel. Ensure they are appropriate for the patient’s weight and mobility. Reset to default if uncertain.
Test Bed on a Known Good Outlet
- Move the bed to a different power outlet if possible. Electrical interference or fluctuations can sometimes cause false alarms.
Observe Alarm Behavior During Testing
- Without a patient, gently simulate movement on the mattress to confirm the alarm triggers appropriately. Ensure it does not activate unexpectedly.
If the Problem Persists
External causes have been ruled out. Remove the bed from service, label it Out of Service, and send it for bench evaluation or repair. Continuing use without resolution may compromise patient safety.
Clinical Use Tip
Never troubleshoot alarms on an occupied bed without patient support. Always prioritize patient transfer and use only safe test movements.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Bed exit alarm activates without patient movement."
Cause
What was observed during troubleshooting.
Example:
"Sensor misaligned under mattress and sensitivity set too high."
Resolution
What action was taken.
Example:
"Realigned sensor, adjusted sensitivity, tested alarm function."
Helpful Details to Include
- Mattress correctly positioned
- Sensor cables secure
- Alarm sensitivity setting
- Outlet tested
- Simulated movement testing results
Final Thought
False alarms can compromise patient safety and care efficiency. Logical troubleshooting, careful observation, and proper escalation protect patients and ensure reliable alarm function. Document all steps clearly.
That is successful troubleshooting.
