What This Guide Helps With
This guide addresses the E1 System High Pressure Error, which occurs when system pressure exceeds safe operating limits. This condition interrupts compression therapy and may be caused by airflow restrictions, improper garment use, or external factors affecting pressure regulation.
Step-by-Step Troubleshooting
1. Ensure Patient Safety First
- Remove the device from active patient use if therapy is not functioning properly
- Apply an alternate DVT prevention method if needed
- Ensure the patient remains safe and supported
2. Verify the Reported Error and Behavior
- Power on the device and confirm the E1 error is displayed
- Observe when the error occurs (startup or during inflation)
- Check if compression stops immediately
- Note any alarms or indicators
3. Inspect Tubing for Kinks or Obstructions
- Check all tubing from the device to the garments
- Look for bent, pinched, or kinked sections
- Ensure tubing is not trapped under bed rails or mattress
- Straighten any restrictions
4. Check Garment Placement and Patient Interaction
- Ensure sleeves or cuffs are applied correctly and not overly tight
- Check for patient positioning issues (e.g., feet pressing against footboard)
- Reposition the patient if necessary
5. Inspect Garments for Twisting or Compression
- Check that garments are not twisted or folded
- Ensure even distribution around the limb
- Replace garments if stiff, worn, or damaged
6. Check for Blocked or Damaged Connectors
- Disconnect and reconnect tubing securely
- Inspect connectors for debris or blockage
- Try a known-good tubing set if available
7. Perform Manual Reset and Retest
- Power cycle or reset the device per manufacturer instructions
- Reconnect to a test setup and observe a full inflation cycle
- Confirm normal operation without error
If the Problem Persists
If the error continues after all external checks, external causes have been ruled out. The issue may indicate an internal pressure sensor, valve, or control failure.
- Remove the device from service
- Label as Out of Service
- Send for repair or bench evaluation
Clinical Use Tip
Never troubleshoot compression devices while connected to a patient. Always ensure alternative DVT prevention is in place before removing therapy.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Device displaying E1 System High Pressure Error; compression therapy stopped during use."
Cause
What was observed during troubleshooting.
Example:
"Kinked tubing and patient positioning caused restricted airflow and elevated system pressure."
Resolution
What action was taken.
Example:
"Straightened tubing, repositioned patient, and reset device. Verified normal operation."
Helpful Details to Include (If Known)
- Alarm behavior
- Accessories swapped
- Power behavior
- Environmental factors
- Indicator lights
- Final device status
Final Thought
High pressure errors are often caused by simple external restrictions. Always start with tubing and patient interaction before assuming device failure. Proper escalation and clear documentation ensure safe and effective resolution.
That is successful troubleshooting.
