What This Guide Helps With

Troubleshoot air surface inflation failures, pressure loss, or unstable support zones caused by power, hoses, connections, positioning, or surface damage.

Step-by-Step Troubleshooting

1. Protect the Patient From Loss of Support

An air surface that does not maintain pressure may compromise pressure redistribution and patient positioning.

Expected outcome: The patient receives reliable support while the affected surface is removed from clinical use for troubleshooting.

2. Confirm the Inflation Problem

Determine whether the entire surface or an individual zone is affected.

Expected outcome: The affected zone and failure pattern are identified.

3. Verify Electrical Power

Inspect the bed and applicable surface-control power connections.

Expected outcome: The surface system receives stable power and responds to authorized controls.

4. Inspect Surface Hoses and Connections

Examine accessible pneumatic connections.

Expected outcome: Air connections are secure and unobstructed.

If reconnecting an approved hose restores inflation, continue with pressure-retention verification.

5. Inspect Mattress Positioning and External Damage

Examine the surface without opening internal components.

Expected outcome: The surface is correctly positioned and has no obvious external damage or restriction.

6. Verify Surface Controls and Therapy Selection

Check the intended operating configuration.

Expected outcome: The surface is configured for the intended support function.

7. Observe Inflation and Pressure Retention

With the bed unoccupied, follow the approved functional test procedure.

Expected outcome: The surface inflates correctly and maintains its intended pressure or support state.

8. Verify Surface Performance

After correcting an external issue:

Expected outcome: The surface provides stable support and passes all applicable functional checks.

Troubleshooting can stop when inflation, pressure retention, and alarm functions are verified.

If the Problem Persists

If power, hoses, connections, positioning, surface condition, and controls have been checked, common external causes have been ruled out.

Possible service-level causes include pneumatic leakage, air delivery, pressure sensing, valve control, or surface electronics.

The affected bed or surface should be:

Do not return a surface that cannot reliably maintain patient support.

Clinical Use Tip

A partially inflated bariatric surface may appear usable while providing inadequate pressure redistribution. Verify all required zones before patient placement.

Work Order Documentation (CCR Method)

CCR = Complaint, Cause, Resolution

Complaint

What was reported by the clinical staff.

Example:
"Nursing reported that the Compella air surface repeatedly lost inflation in one support zone."

Cause

What was observed during troubleshooting.

Example:
"Clinical Engineering found a partially disconnected external air hose at the surface connection."

Resolution

What action was taken.

Example:
"Secured the hose and verified normal zone inflation, pressure retention, and surface alarm operation."

Helpful Details to Include (If Known)

Final Thought

Patient support must remain the priority when evaluating air surface failures. Check power, connections, hoses, positioning, and controls before assuming an internal pneumatic fault. Verify pressure retention, escalate unresolved problems, and document the corrective action.

That is successful troubleshooting.
