What This Guide Helps With
Helps troubleshoot failed shock delivery related to charging, electrodes, connections, battery, or operational conditions.
Step-by-Step Troubleshooting
1. Confirm Patient Safety and Equipment Availability
If the device is needed during an emergency, immediately use another verified defibrillator. Do not delay patient care troubleshooting the affected unit. Expected outcome: Emergency response capability is maintained.
2. Confirm the Reported Shock Delivery Failure
Verify whether the device advised a shock but did not deliver when the shock control was activated. Document the observed behavior. Expected outcome: The reported failure is confirmed.
3. Verify Battery Condition
Check battery status and ensure adequate power is available. Replace with a verified compatible battery if needed. Expected outcome: Device has sufficient power for operation.
4. Inspect Electrode Connection
Verify electrode pads and connector are properly installed and connected. Expected outcome: Shock delivery path is confirmed externally.
5. Inspect Controls and Physical Condition
Check for visible damage, contamination, or damaged controls that could affect operation. Expected outcome: External mechanical causes are ruled out.
6. Perform Approved Functional Verification
Using appropriate test equipment, verify normal device operation according to approved procedures. Expected outcome: Shock delivery function is verified or failure is confirmed for escalation.
7. Escalate Unresolved Shock Delivery Failure
Remove the device from service if shock delivery cannot be verified. Expected outcome: Unsafe equipment is prevented from returning to emergency use.
If the Problem Persists
Common external causes including battery condition, electrode connections, and physical controls have been ruled out. The device should be:
- Removed from service
- Labeled Out of Service
- Sent for repair or bench evaluation
- Evaluated using appropriate manufacturer documentation and approved test equipment
- Repaired or configured only by qualified personnel
Defibrillator performance verification must be completed before return to service.
Clinical Use Tip
A defibrillator that cannot reliably deliver therapy must be replaced immediately with a verified operational unit.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Clinical staff reported that the LIFEPAK 1000 advised a shock but would not deliver therapy."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found the electrode connection was not fully seated."
Resolution
What action was taken.
Example:
"Clinical Engineering corrected the connection, verified shock delivery operation using approved test equipment, and returned the device to service."
Helpful Details to Include (If Known)
- Battery condition
- Shock attempt behavior
- Electrode condition
- Control response
- Functional test results
- Final service status
Final Thought
Defibrillator therapy failures require immediate safety decisions and disciplined troubleshooting. Verify external causes first, stop when service limits are reached, and document all corrective actions. That is successful troubleshooting.
