What This Guide Helps With
Addresses repeated or unexpected bed exit alarms caused by setup, mattress positioning, sensitivity settings, or connection issues.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Confirm the patient is safe and attended to.
- Do not troubleshoot while relying on the alarm for fall prevention.
- Move the patient if needed.
Confirm Alarm Mode and Status
- Verify the bed exit alarm is properly enabled and set to the correct mode (e.g., zone or sensitivity level).
- Incorrect mode can trigger alarms with normal patient movement.
Check Mattress Placement and Type
- Ensure the mattress is properly seated and centered on the deck.
- Misaligned or non-compatible mattresses can interfere with pressure sensing and cause false alarms.
Inspect for Bedding Interference
- Check for excess linens, pads, or items tucked under the mattress.
- These can shift weight distribution and trigger the alarm unexpectedly.
Verify Patient Positioning
- Ensure the patient is positioned correctly within the detection zone.
- Patients near the edge or frequently repositioning can cause repeated alerts.
Check Bed Exit Sensitivity Settings
- Adjust sensitivity to an appropriate level for the patient condition.
- High sensitivity may cause nuisance alarms with minimal movement.
Inspect Sensor and Deck Area
- Look for visible damage, debris, or obstruction under the mattress or on the deck surface.
- Anything affecting pressure distribution can lead to false triggering.
Cycle Bed Power
- Unplug the bed, wait 30 seconds, and restore power.
- This resets system logic and may clear sensor calibration issues.
Check for Recent Mattress or Accessory Changes
- Confirm whether a different mattress, overlay, or accessory was recently installed.
- Non-OEM or incompatible accessories are a common cause of alarm issues.
Test Alarm Functionality
- With the bed empty, activate the alarm and simulate patient movement.
- Alarm should trigger only when appropriate thresholds are met.
- If functioning normally after adjustments, return bed to service.
If the Problem Persists
If all external causes have been ruled out, the issue is likely related to internal sensors, wiring, or control electronics. Remove the bed from service, label it Out of Service, and send for repair or further bench evaluation. Knowing when to stop prevents unnecessary risk and ensures proper resolution.
Clinical Use Tip
Never rely on a bed exit alarm that is producing false alarms. Move the patient to a properly functioning bed before troubleshooting to maintain fall safety.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Bed exit alarm alarming repeatedly without patient attempting to exit bed."
Cause
What was observed during troubleshooting.
Example:
"Mattress misalignment and high sensitivity setting causing improper pressure detection."
Resolution
What action was taken.
Example:
"Repositioned mattress, adjusted sensitivity, and verified proper alarm function."
Helpful Details to Include (If Known)
- Alarm mode and sensitivity level checked
- Mattress type and positioning verified
- Bedding interference assessed
- Alarm tested with and without patient
- Power cycle performed
- Any recent accessory changes noted
- Final device status (returned to service or removed)
Final Thought
Bed exit alarms are highly dependent on proper setup and patient-specific adjustments. Always rule out environmental and configuration factors before assuming failure. Safe escalation and clear documentation are essential to protecting patients and maintaining trust in alarm systems.
That is successful troubleshooting.
