What This Guide Helps With
Addresses missing, distorted, or absent audio prompts, focusing on speaker function, device settings, and external obstructions.
Step-by-Step Troubleshooting
Ensure Patient Safety First
Confirm the AED is not in active use. If a patient requires resuscitation, provide a backup AED. Never troubleshoot on a patient.
Check Volume Settings
Locate the AED volume control (if adjustable). Ensure it is not muted or set too low. Expected outcome: audible prompt when powered on.
Perform a Power Cycle
Turn the AED off, wait 10 seconds, then turn it back on. Observe if the audio prompt initiates. Sometimes software resets resolve minor glitches.
Inspect Speaker Area
Check for dust, debris, or obstruction over the speaker grille. Clean carefully if needed. Expected outcome: unobstructed sound output.
Verify Battery Status
Low or improperly seated batteries can reduce speaker performance. Confirm battery is recognized and fully charged. Expected outcome: normal audio prompts resume.
Check Pads and Connections
Some AEDs may suspend audio if pads are not connected properly. Ensure pads are installed and connectors fully seated. Expected outcome: device recognizes pads and enables prompts.
Test with Built-In Self-Test or Demo Mode
If available, activate the AED’s self-test or demo mode to confirm speaker function without patient involvement. Expected outcome: audio prompts audible.
If the Problem Persists
External causes have been ruled out. The speaker may be internally faulty:
- Remove the device from service.
- Label as Out of Service.
- Send for repair or bench evaluation.
Knowing when to stop protects patient safety and preserves the device.
Clinical Use Tip
Always ensure another AED is available for patient care. Do not rely on an AED with suspected audio failure during resuscitation.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"AED audio prompts not audible during device power-on."
Cause
What was observed during troubleshooting.
Example:
"Speaker malfunction or obstruction confirmed after external checks."
Resolution
What action was taken.
Example:
"Device removed from service, labeled Out of Service, sent for repair."
Helpful Details to Include (If Known)
- Battery checked and fully charged
- Volume setting verified
- Pads properly connected
- No debris in speaker grille
- Indicator lights normal
- Device removed from service
Final Thought
Patient safety requires ensuring functional AED audio prompts. Troubleshoot logically from simple external causes to escalation. Proper documentation ensures future reference and accountability.
That is successful troubleshooting.
