What This Guide Helps With
Troubleshoot powered positioning that fails after manual CPR release due to incomplete mechanism reset, obstruction, controls, or position-related faults.
Step-by-Step Troubleshooting
1. Ensure Patient Safety and Maintain Emergency Positioning Capability
Determine whether the bed is occupied or needed for immediate patient care.
If powered positioning cannot be restored reliably, arrange another verified bed.
Do not repeatedly activate the CPR release while a patient depends on the bed.
Perform testing with the bed unoccupied and secured.
Expected outcome: Patient care is maintained without relying on an unreliable positioning mechanism.
2. Confirm the Reported CPR and Motion Behavior
Ask whether the manual CPR release lowered the head section normally.
Determine whether powered motion stopped immediately after release or whether the problem existed previously.
Identify which powered movements remain unavailable.
Expected outcome: The relationship between CPR release and powered motion failure is established.
3. Inspect the Manual CPR Release Control
Inspect the accessible release handle and cable path for visible damage, obstruction, or abnormal positioning.
Verify that the release control has returned to its normal position.
Do not force a damaged release mechanism.
Expected outcome: The manual CPR control is visibly returned to its normal operating position.
4. Check for Mechanical Obstructions
Inspect the head section, deck linkage, mattress, and nearby accessories.
Look for trapped linens, equipment cables, or objects preventing normal deck movement.
Keep hands clear of moving components and pinch points.
Expected outcome: No external obstruction prevents the head section from moving.
5. Verify AC Power and Controls
Confirm that the bed receives power from a verified outlet.
Check whether other powered functions operate.
Inspect caregiver controls and applicable lockouts.
Determine whether the failure is limited to the head section or affects multiple movements.
Expected outcome: Power and authorized controls operate normally.
6. Verify the Release Mechanism Is Properly Reset
Using the applicable Stryker instructions, confirm that the CPR release mechanism is in its required normal operating condition.
Do not manually force the deck into position or bypass any latch or safety interlock.
If the mechanism cannot be confirmed properly reset, stop testing and escalate.
Expected outcome: The release mechanism is correctly positioned for powered operation.
7. Attempt Controlled Powered Movement
With the bed unoccupied, command the affected function through a small safe range.
Observe whether movement begins normally.
Stop immediately if the deck binds, moves unexpectedly, produces unusual noise, or fails to support itself.
Expected outcome: Powered motion resumes smoothly without abnormal behavior.
8. Perform Final CPR and Positioning Verification
If the problem has been corrected, verify powered head-section movement and stopping.
Perform the applicable manufacturer-approved CPR release and reset verification.
Confirm that the deck returns to normal powered operation after the test.
If all required checks pass, troubleshooting can stop.
Expected outcome: Manual CPR release and powered positioning both operate reliably.
If the Problem Persists
External controls, power, obstructions, and the accessible release mechanism have been checked.
Remaining causes may include CPR release linkage, actuator engagement, position feedback, drive components, or internal control circuitry.
Remove the bed from service, label it Out of Service, and arrange qualified repair or bench evaluation.
Use applicable Stryker service documentation and approved test equipment. Do not force the mechanism or attempt unauthorized internal adjustments.
Complete CPR release, reset, and powered positioning verification before return to service.
Knowing when to stop external troubleshooting is proper troubleshooting.
Clinical Use Tip
After any CPR release mechanism service, verify that powered head-section positioning has been restored before returning the bed to patient care.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Nursing reported that the Secure II head section would not raise electrically after the manual CPR release was used."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found that the accessible CPR release handle had not fully returned to its normal position."
Resolution
What action was taken.
Example:
"Returned the handle to its normal position according to the approved instructions and verified powered head movement and CPR release reset operation."
Helpful Details to Include (If Known)
- CPR release behavior
- Position of the release handle
- Affected powered functions
- AC power status
- Lockout status
- Mechanical obstructions
- Visible linkage condition
- Unusual movement or noise
- Reset verification
- Final CPR and powered motion test results
Final Thought
CPR release and powered positioning must both remain dependable. Inspect the accessible release mechanism, controls, power, and obstructions before considering internal failure. Stop when the mechanism behaves abnormally, escalate appropriately, and document the final verification.
That is successful troubleshooting.
