What This Guide Helps With
Evaluating post-use damage, contamination, or fluid exposure and determining whether cleaning, functional verification, or service removal is appropriate.
Step-by-Step Troubleshooting
1. Remove the Device From Clinical Availability
Do not immediately return an AutoPulse to service after significant impact, contamination, or suspected fluid intrusion.
Provide another verified AutoPulse or alternate CPR device for readiness.
Expected outcome: The suspect platform is isolated while emergency coverage remains available.
2. Identify the Exposure or Damage
Determine what occurred:
- Device dropped or struck
- Blood or body-fluid contamination
- Cleaning solution exposure
- Fluid spilled onto or into the platform
- Housing crack
- Damaged control panel
- Damaged LifeBand
- Battery contamination
Document the affected area and approximate circumstances.
Expected outcome: The event is characterized well enough to decide whether external cleaning and testing are appropriate.
3. Inspect Before Applying Power
If fluid intrusion is suspected, do not power the platform on simply to see whether it still works.
Inspect for:
- Wetness
- Residue
- Fluid around seams
- Moisture around the battery interface
- Corrosion
- Burn odor
- Housing separation
- Cracks
Expected outcome: No evidence of internal fluid intrusion or unsafe physical damage is present. If intrusion is suspected, remove the device from service and stop troubleshooting.
4. Remove and Inspect the Battery
Remove the battery and inspect both the battery and accessible platform interface.
Do not reuse a battery that is wet, damaged, swollen, cracked, or otherwise questionable.
Expected outcome: The battery and interface are dry, intact, and free of unsafe contamination.
5. Inspect the LifeBand
Check the LifeBand for:
- Blood or fluid contamination
- Tears
- Fraying
- Deformation
- Damage to attachment areas
- Material that cannot be adequately cleaned
Expected outcome: The LifeBand is serviceable or is removed from use and replaced if damaged or unsuitable for continued use.
6. Clean and Disinfect Accessible Surfaces
Perform cleaning and disinfection using approved products and methods appropriate for the device.
Avoid excessive liquid application around seams, openings, controls, contacts, or battery interfaces.
Expected outcome: External contamination is removed without introducing additional moisture or damage.
7. Reinspect After Cleaning
Once fully dry, inspect again for:
- Cracks revealed after cleaning
- Clouding or chemical damage
- Sticking controls
- Loose housing
- Damaged labels or interfaces
- Residual contamination
Expected outcome: The device is externally clean and structurally intact. Any unresolved damage requires removal from service.
8. Perform Controlled Power-On Testing
Only if no fluid intrusion or unsafe damage is suspected, install a known-good charged battery and perform a normal non-patient startup check.
Observe the display, controls, LifeBand movement, and unusual sound or odor.
Expected outcome: The AutoPulse powers on normally and shows no abnormal behavior.
9. Complete Functional Verification
Perform the applicable approved functional and return-to-service testing following the exposure event.
A visual inspection alone is not sufficient after significant impact or contamination.
Expected outcome: The platform passes required operational checks without abnormal noise, control problems, LifeBand issues, or intermittent failure. If so, troubleshooting can stop.
10. Escalate Damage or Suspected Fluid Intrusion
Remove the AutoPulse from service if there is:
- Suspected internal fluid entry
- Cracked or separated housing
- Corrosion
- Persistent contamination
- Abnormal operation after cleaning
- Unusual odor or heat
- Damaged controls
- Failed functional testing
Expected outcome: The platform is routed for qualified evaluation instead of being returned to emergency use.
If the Problem Persists
External cleaning, visual inspection, battery evaluation, accessory inspection, and safe functional testing have been completed where appropriate.
Remaining concerns may involve internal contamination, hidden mechanical damage, electrical damage, compromised controls, or other service-level conditions. The device should be:
- Removed from service
- Labeled Out of Service
- Sent for repair or bench evaluation
- Evaluated using appropriate ZOLL documentation and approved test equipment
- Repaired only by qualified personnel
Do not open the platform simply to investigate suspected fluid entry unless authorized service procedures specifically require it.
After repair or significant exposure evaluation, complete all required return-to-service testing before clinical deployment.
Knowing when to stop external troubleshooting is proper troubleshooting.
Clinical Use Tip
After a resuscitation, inspect the AutoPulse before restocking it so contamination or impact damage is not discovered during the next emergency.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Staff reported that the AutoPulse was heavily contaminated with body fluid after use and required evaluation before being returned to service."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found external contamination on the platform and LifeBand but no visible evidence of fluid intrusion or structural damage."
Resolution
What action was taken.
Example:
"Cleaned and disinfected the device using approved procedures, replaced the contaminated LifeBand, completed functional testing, and verified normal operation."
Helpful Details to Include (If Known)
- Type and location of contamination
- Whether fluid intrusion was suspected
- Drop or impact history
- Housing condition
- Battery condition
- LifeBand condition
- Cleaning performed
- Signs of heat, odor, corrosion, or moisture
- Functional test results
- Final return-to-service or removal status
Final Thought
Post-use contamination or damage requires deliberate inspection before power-up or restocking. Protect emergency readiness, verify external condition and function, and escalate suspected internal fluid or structural damage instead of taking unnecessary risks.
That is successful troubleshooting.
