What This Guide Helps With
This guide addresses Error E2 High Pressure (Leg Sleeves or Foot Cuffs), which occurs when pressure exceeds normal limits due to restricted airflow, improper sleeve/cuff fit, or external compression. This condition can interrupt therapy and cause excessive compression on the patient.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Remove the device from active patient use if compression feels excessive or uncomfortable
- Apply an alternate DVT prophylaxis method if needed
- Ensure patient circulation is not compromised
Verify the Reported Error and Behavior
- Power on the unit and confirm Error E2 is displayed
- Observe when the error occurs (startup vs during compression cycles)
- Check if sleeves inflate excessively or therapy stops
Check Sleeve or Cuff Fit (Most Common Cause)
- Ensure sleeves/cuffs are not wrapped too tightly
- Verify correct sizing for the patient
- Reapply sleeves to allow proper spacing and circulation
Inspect Tubing for Kinks or Partial Occlusion
- Trace tubing from device to sleeves/cuffs
- Look for kinks, bends, or compression under equipment
- Straighten or reposition tubing as needed
Check for Patient or Environmental Interference
- Ensure patient is not lying on tubing
- Verify limbs are not pressed tightly against bed frame or footboard
- Confirm nothing is compressing sleeves externally
Reconnect and Restart the Device
- Power cycle or reset the device
- Reconnect tubing securely
- Restart therapy and monitor for recurrence
Swap Sleeves or Tubing (Isolation Step)
- Replace sleeves/cuffs with known-good accessories
- Swap tubing if available
- Check if error clears after replacement
If the Problem Persists
If all external causes such as sleeve fit, tubing, and environmental factors have been ruled out and the error continues, this indicates a likely internal issue.
- Remove device from service
- Label Out of Service
- Send for repair or bench evaluation
Clinical Use Tip
Never troubleshoot or continue therapy on an active patient when compression feels abnormal. Always transfer the patient to a known working SCD unit first.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Device displaying E2 High Pressure error during therapy; sleeves feel excessively tight."
Cause
What was observed during troubleshooting.
Example:
"Leg sleeve applied too tightly and tubing partially kinked, causing elevated pressure."
Resolution
What action was taken.
Example:
"Adjusted sleeve fit, corrected tubing routing, reset device, and confirmed 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 most often caused by external restrictions rather than device failure. Always verify fit, tubing, and environment before escalating. Proper troubleshooting protects both patient safety and equipment reliability.
That is successful troubleshooting.
