What This Guide Helps With
Error E13 where the SCD cannot detect pressure increase, resulting in failed therapy cycles and inability to provide compression.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Remove the device from active patient use immediately if therapy is not functioning
- Apply an alternate DVT prevention method if needed
Expected: Patient continues receiving appropriate therapy
Why it matters: Loss of compression therapy increases DVT risk
Verify the Reported Error and Behavior
- Power on the unit and confirm Error E13 is displayed
- Observe when the error occurs (startup or inflation cycle)
- Check if sleeves do not inflate or inflate minimally
- Note if the unit stops therapy or alarms
Expected: Error is consistently present and reproducible
Why it matters: Confirms a true sensing failure, not intermittent use issue
Check Sleeve Connections and Tubing (Most Common External Cause)
- Ensure tubing is fully connected to the device ports
- Check for loose fittings
- Look for kinks, occlusions, or disconnections
Expected: Tubing is secure with no airflow restriction
Why it matters: Blocked or disconnected tubing prevents pressure buildup, mimicking transducer failure
Inspect Sleeves for Leaks or Damage
- Check for tears, holes, or worn areas
- Listen for air leaks during inflation attempt
- Swap with known good sleeves if available
Expected: Sleeves hold air and inflate normally
Why it matters: Air leaks prevent pressure rise, triggering E13
Verify Proper Sleeve Application and Fit
- Confirm proper sizing and secure wrap
- Ensure no excessive looseness allowing air escape
Expected: Sleeves inflate with resistance
Why it matters: Poor fit can reduce measurable pressure rise
Test Device Without Sleeves (Isolation Check)
- Disconnect sleeves and briefly run the device
- Observe if pump attempts to build pressure
- Listen for pump operation
Expected: Pump runs but cannot build pressure without load
Why it matters: Helps determine if issue is external (sleeves/tubing) vs internal sensing
Power Cycle the Device
- Turn the unit off, wait 10–15 seconds, and restart
Expected: Error clears only if transient
Why it matters: Rules out temporary startup fault
If the Problem Persists
External causes have been ruled out. The device is unable to detect pressure rise internally. This strongly indicates a failed pressure transducer or internal pneumatic issue.
- Remove device from service
- Label Out of Service
- Send to Cardinal Health or qualified repair vendor
Clinical Use Tip
Never troubleshoot an SCD while actively connected to a patient. Always verify compression therapy on a working unit before relying on it for DVT prevention.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Device displaying Error E13 Pressure Transducer Error. Sleeves not inflating during therapy."
Cause
What was observed during troubleshooting.
Example:
"Unable to detect pressure rise after verifying tubing and sleeves. Likely internal pressure sensing failure."
Resolution
What action was taken.
Example:
"Removed from service, labeled out of service, and sent to manufacturer for repair."
Helpful Details to Include (If Known)
- When error occurs (startup vs during inflation)
- Tubing condition and connection status
- Sleeves swapped with known good set
- Pump sound during operation
- Any observed air leaks
- Final device disposition
Final Thought
Error E13 represents a failure to confirm pressure generation. Always rule out simple airflow issues first, but recognize persistent errors as internal failures requiring service. Patient safety and proper escalation are critical.
That is successful troubleshooting.
