What This Guide Helps With
This guide addresses situations where the Stryker InTouch bed triggers bed exit alarms incorrectly or fails to trigger them when a patient moves. Symptoms may include:
- Alarm sounding even when the patient is stationary
- Alarm not sounding when the patient leaves the bed
- Intermittent or inconsistent alarm behavior
- Bed exit indicator lights flashing erratically
Focus is on external and easily verifiable issues first, ensuring patient safety and proper function before assuming internal faults.
Step-by-Step Troubleshooting
Verify Bed Power
- Check that the bed is plugged in and powered on.
- Confirm the display is active and shows normal startup messages.
- Why: Low or intermittent power can cause alarm circuits to behave erratically.
Inspect Bed Exit Sensor Pads / Mats
- Ensure sensor pads are correctly positioned under the mattress and not folded or bunched.
- Confirm connectors are fully seated at the bed and pad ends.
- Look for visible damage, frayed wires, or moisture.
- Why: Misaligned or damaged pads often cause false or missing alarms.
Check Bed Rails and Safety Settings
- Ensure side rails are in the proper position per facility protocol. Some alarm logic depends on rail positions.
- Confirm bed exit alarm is enabled in the user settings menu.
- Why: Incorrect settings or rail positions can prevent the system from recognizing patient movement.
Verify Mattress and Weight Thresholds
- Confirm that the mattress in use is compatible with the bed’s bed exit sensor system.
- If possible, simulate patient weight by pressing gently on the pad to see if the alarm triggers.
- Why: The system uses pressure detection; incorrect mattress types or weight distributions can affect sensitivity.
Inspect Cables and Connectors
- Check all sensor cables for secure connections and signs of wear or damage.
- Re-seat connectors at both the bed and sensor ends.
- Why: Loose connections are a common source of intermittent alarms.
Bed Software / Settings Check
- Access the bed’s configuration menu and verify alarm delays, sensitivity, and sound settings.
- Reset to default settings if persistent false alarms occur.
- Why: Software misconfigurations can mimic hardware faults.
Observe Alarm Behavior During Simulation
- With the bed empty, gently step on or lift the pad to verify alarm triggers.
- Note any irregularities such as delayed or absent alarms.
- Why: Confirms the problem is consistent and reproducible before escalating.
If the Problem Persists
All external checks and configuration verification have been completed.
Likely internal fault in the bed exit alarm circuitry or control board.
- Remove bed from patient service.
- Label as “Out of Service.”
- Send for repair or bench evaluation by qualified biomedical personnel.
Knowing when to escalate prevents unsafe patient situations and avoids unnecessary component replacement.
Clinical Use Tip
- Never troubleshoot bed exit alarms with a patient in the bed.
- Move the patient to another safe bed before performing tests.
- Ensure alarms are fully operational before returning the bed to service.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
“Bed exit alarm triggers intermittently, sometimes without patient movement.”
Cause
What was observed during troubleshooting.
Example:
“Sensor pads improperly seated and one connector partially loose.”
Resolution
What action was taken.
Example:
“Repositioned sensor pads and re-seated all connectors. Alarm successfully tested and confirmed functional.”
Helpful Details to Include
- Pad placement and mattress type
- Bed rail positions during testing
- Alarm sensitivity and delay settings
- Connector condition and cable routing
- Test results (simulated weight or empty bed)
- Final bed status
Final Thought
Proper troubleshooting of bed exit alarms prioritizes patient safety and logical, stepwise checks. Verifying sensors, connections, and software settings before escalating preserves resources and ensures beds remain safe for patient use. Documentation of all steps is critical for maintenance tracking and quality assurance.
That is successful troubleshooting.
