What This Guide Helps With
Garment not detected or therapy not starting due to connection issues, incompatible sleeves, or external pneumatic faults.
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 connect the garment. Observe for recognition or error indication.
- Expected: Unit fails to detect garment or does not initiate therapy.
- Why it matters: Confirms true detection issue vs normal startup delay.
Check Garment Connection
- Disconnect and firmly reconnect the tubing to the device port. Ensure it is fully seated.
- Expected: Secure, tight connection with no looseness.
- Why it matters: Loose or partial connections are the most common cause of non-recognition.
- If garment is recognized → stop troubleshooting.
Inspect Tubing and Connectors
- Check tubing for kinks, cracks, or damaged connectors. Inspect the port for debris or bent pins (if applicable).
- Expected: Clean, intact tubing and connectors with no obstruction.
- Why it matters: Airflow restriction or connector damage can prevent proper detection.
- If corrected and recognized → stop troubleshooting.
Confirm Correct Garment Type
- Verify the garment being used is compatible with the Hydroven Series (correct model and type).
- Expected: Approved garment type connected.
- Why it matters: Some systems will not recognize incompatible or incorrect garments.
- If incorrect garment replaced and recognized → stop troubleshooting.
Swap with a Known Good Garment
- Connect a known working garment to the unit.
- Expected: Device recognizes the known good garment.
- Why it matters: Helps determine if the issue is with the garment or the device.
- If new garment works → original garment is faulty
- If issue persists → continue troubleshooting
Inspect for Air Leaks During Startup
- Run the unit and listen for air leaks at the connection or along the tubing.
- Expected: No audible leaks.
- Why it matters: Leaks can prevent pressure sensing required for garment detection.
Perform a Power Cycle
- Turn the unit off, disconnect power if applicable, wait 30 seconds, then restart.
- Reconnect the garment and retest.
- Expected: Device resets and attempts normal detection.
- Why it matters: Clears minor control or detection faults.
- If resolved → stop troubleshooting.
If the Problem Persists
All common external causes have been ruled out. The issue is likely internal (pressure sensing, port detection, or control board fault).
Remove the device from service, label it Out of Service, and send for repair or bench evaluation.
Clinical Use Tip
Never troubleshoot garment recognition issues while connected to a patient. Always transition the patient to another device before testing.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"SCD not recognizing garment and therapy not starting."
Cause
What was observed during troubleshooting.
Example:
"Faulty garment tubing preventing proper pressure detection."
Resolution
What action was taken.
Example:
"Replaced garment with known good unit; device function restored."
Helpful Details to Include (If Known)
- Outlet tested (if applicable)
- Tubing condition verified
- Alternate garment tested
- Any alarm or indicator behavior
- Presence of air leaks
- Final device status (returned to service or sent to repair)
Final Thought
Start with simple connection and accessory checks before assuming device failure. Most garment recognition issues are external. Knowing when to escalate ensures patient safety and efficient workflow. Proper documentation supports future troubleshooting and trending.
That is successful troubleshooting.
