What This Guide Helps With

Pump runs with little/no pressure or no inflation despite proper setup, suggesting possible internal compressor failure after external causes are ruled out.

Step-by-Step Troubleshooting

Ensure Patient Safety First

• Remove the device from active patient use before troubleshooting.
• Expected: Patient placed on alternate DVT prophylaxis.

Verify the Reported Issue

• Power on the unit and observe operation during a full cycle. Listen for compressor activity and check for sleeve inflation.
• Expected: Compressor runs but no pressure builds, or compressor is silent with no inflation.
• Why it matters: Confirms true performance issue vs setup or accessory problem.

Check Power and Unit Status

• Ensure the unit powers on fully with normal indicators (lights/display).
• Expected: Unit powers on consistently with no power interruptions.
• Why it matters: Low or unstable power can mimic compressor failure.

Inspect Tubing Connections

• Disconnect and reconnect tubing at the pump and garment ports. Ensure secure fit.
• Expected: Tight, fully seated connections.
• Why it matters: Loose or partially connected tubing prevents pressure buildup.
• If corrected and inflation returns → stop troubleshooting.

Inspect Sleeve (Garment) and Tubing for Leaks

• Check for holes, tears, or disconnections. Listen for escaping air during operation.
• Expected: No visible damage or audible leaks.
• Why it matters: External leaks are the most common cause of no pressure.
• If leak found and corrected → stop troubleshooting.

Swap with Known-Good Sleeve and Tubing

• Replace the sleeve and tubing with a verified working set.
• Expected: Normal inflation with known-good accessories.
• Why it matters: Confirms whether the issue is accessory-related or internal to the pump.
• If issue resolves → original accessories are defective.

Check for Kinks or Obstructions in Tubing

• Ensure tubing is not kinked, pinched, or compressed along its length.
• Expected: Free, unobstructed airflow path.
• Why it matters: Restricted airflow can prevent pressure from reaching the sleeve.
• If corrected and function returns → stop troubleshooting.

Listen for Compressor Operation

• With tubing connected, listen for compressor motor sound during inflation phase.
• Expected: Audible compressor cycling during operation.
• No sound → possible compressor or motor failure
• Sound present but no pressure → possible internal leak or compressor inefficiency
• Why it matters: Helps differentiate electrical vs pneumatic internal failure.

If the Problem Persists

If all external causes (power, tubing, sleeve, connections) have been ruled out and the unit still fails to generate pressure, the issue is likely internal (compressor, valves, or pneumatic system).

The device should be:

• Removed from service
• Labeled Out of Service
• Sent for repair or bench evaluation

Knowing when to stop is proper troubleshooting and prevents unnecessary risk.

Clinical Use Tip

Never troubleshoot an SCD while connected to a patient. Always transfer the patient to a functioning device before evaluating compression issues.

Work Order Documentation (CCR Method)

CCR = Complaint, Cause, Resolution

Complaint

What was reported by the clinical staff.

Example:
"SCD sleeves not inflating; no compression therapy observed during use."

Cause

What was observed during troubleshooting.

Example:
"Internal compressor failure suspected after confirming power, tubing, and sleeves were functional with known-good components."

Resolution

What action was taken.

Example:
"Removed unit from service, labeled out of service, and sent to Biomed shop/vendor for compressor repair evaluation."

Helpful Details to Include (If Known)

• Unit powers on normally
• No pressure felt at tubing output
• Compressor silent or running without output
• Known-good sleeve/tubing tested
• No visible leaks or kinks
• No unusual smell or overheating
• Final device status

Final Thought

Effective troubleshooting means ruling out all external causes before concluding internal failure. This protects patients, reduces unnecessary repairs, and ensures accurate documentation. Recognizing compressor failure early prevents delays in therapy and supports proper equipment management.

That is successful troubleshooting.
