What This Guide Helps With
Troubleshooting a CPR release or emergency-lowering problem caused by obstruction, loading, positioning, external damage, adjustment, or mechanical failure.
Step-by-Step Troubleshooting
1. Ensure Patient Safety and Emergency Readiness
Do not test or troubleshoot the CPR release while a patient is on the bed unless it is required for an actual emergency and used by trained clinical staff.
If the function is reported unreliable, notify clinical staff and move the patient to another verified bed as soon as clinically safe. Maintain access to an alternate emergency response method.
Expected outcome: The patient is not dependent on an unverified emergency-lowering function.
2. Confirm the Exact Reported Condition
Determine whether:
The CPR handle or control will not move.
The handle moves but the head section does not lower.
The section lowers slowly, partially, or unevenly.
The function works from one side but not the other.
The section will not relatch or return to powered operation.
The issue occurred during an actual event or routine test.
Expected outcome: The failure is clearly defined before any hands-on testing.
3. Remove the Bed From Patient Use for Testing
Transfer the patient to another verified bed and remove loose equipment, tubing, and accessories that could be damaged or trapped.
Set the brakes and create adequate clearance around the head section. Keep hands, tools, and cables away from pinch points.
Expected outcome: The bed is safely prepared for controlled CPR-function testing.
4. Inspect the CPR Controls Externally
Inspect each CPR release handle or control for:
Cracks, bending, looseness, or impact damage.
Obstruction by linens, equipment, wall fixtures, or accessories.
Restricted movement caused by improper cable routing.
Labels or covers interfering with access.
Evidence of fluid, debris, or misuse.
Do not force a stuck control.
Expected outcome: CPR controls are accessible, unobstructed, and free of visible damage. A simple obstruction may be corrected and the function retested.
5. Check the Head-Section Load and Position
Remove nonessential equipment from the head section.
Confirm that the bed is not positioned against a wall, boom, shelf, or other object that prevents downward movement. Verify that attached accessories and cables have sufficient clearance.
Expected outcome: No external load or room obstruction prevents emergency lowering.
6. Perform a Controlled CPR Release Test
Follow the approved external operating procedure while supporting and observing the head section from a safe position.
Test each applicable release location separately. Do not place any part of the body beneath the moving section.
Expected outcome: The release activates smoothly and the head section lowers as intended. If it operates normally after removing an obstruction, repeat the test and inspect for damage before stopping.
7. Observe Mechanical Response
During the controlled test, note whether:
The handle travels normally.
The release feels loose, disconnected, or unusually resistant.
The head section begins moving but binds.
Movement is uneven.
A cable or linkage is visibly not following the control.
Abnormal grinding, popping, or structural movement occurs.
Stop testing immediately if uncontrolled movement, structural damage, or abnormal noise is present.
Expected outcome: The response is smooth and repeatable, or a service-level mechanical problem is identified for escalation.
8. Verify Reset and Normal Powered Operation
After the emergency-lowering test, return the head section to its normal latched or powered state according to approved procedures.
Verify that:
The section remains secure.
Powered head elevation and lowering operate normally.
No warning or abnormal movement remains.
The CPR control returns to its normal position.
Expected outcome: Both emergency lowering and normal powered operation function correctly. Troubleshooting can stop.
9. Inspect for External Damage After a Reported Emergency Event
If the CPR release was used during an actual clinical event, inspect the bed for deformation, loose accessories, trapped cables, damaged controls, or signs that the section was forced or overloaded.
Expected outcome: No secondary damage is present. Any damage requires removal from service.
10. Escalate an Unresolved CPR Failure
Remove the bed from service if the CPR release is stiff, intermittent, damaged, incomplete, uneven, or cannot be reset reliably.
Label the bed Out of Service and send it for bench evaluation. Do not return it to clinical use based solely on normal powered head movement.
Expected outcome: A bed with an unreliable emergency function is not used for patient care.
If the Problem Persists
External obstruction, loading, position, control access, and basic reset conditions have been ruled out. The remaining cause may involve the release cable, linkage, latch, damper, head-section mechanics, or related internal components.
The bed must be removed from service, labeled Out of Service, and evaluated using appropriate Stryker documentation and approved test equipment. Mechanical repair and adjustment should be performed only by qualified personnel. Both emergency lowering and normal powered head-section operation must be verified before return to service.
Knowing when to stop external troubleshooting and escalate is proper troubleshooting.
Clinical Use Tip
A bed with normal powered head motion may still be unsafe if its independent CPR release cannot be verified.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Nursing reported that the InTouch CPR release handle moved but the head section would not lower."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found an accessory cable routed tightly across the head-section movement path and restricting emergency lowering."
Resolution
What action was taken.
Example:
"Clinical Engineering rerouted and secured the cable, then verified repeated CPR lowering, reset, and normal powered head movement."
Helpful Details to Include (If Known)
- CPR control location tested.
- Whether the control moved.
- Whether the head section lowered fully and evenly.
- Bed and head-section position.
- Accessories, cables, or obstructions found.
- Abnormal resistance, sound, or structural movement.
- Ability to reset the section.
- Powered head-motion result after reset.
- Whether the issue occurred during an actual event.
- Final emergency and powered-function status.
Final Thought
Protect the patient, test emergency lowering only under controlled conditions, rule out external interference before assuming mechanical failure, and remove the bed from service whenever the CPR function is unreliable.
That is successful troubleshooting.
