LIFEPAK CR Plus and LIFEPAK Express defibrillators
PHYSIO-CONTROL, INC. · Model 97403
ASSY-LPCR PLUS,AUTO,ENGLISH,AHA2005
Intended use: A portable electronic device designed to automatically detect cardiac arrhythmias (ventricular fibrillation/pulseless ventricular tachycardia) in a sudden cardiac arrest (SCA) patient, after which it automatically activates defibrillation of the heart through application of electrical shocks to the chest surface. The device is placed in conspicuous public locations and is intended to be applied to the patient by a layperson. It consists of an external pulse generator (EPG) with a cardiac rhythm recognition system and a pair of skin-adhesive electrodes to monitor the rhythm and deliver the shocks; it includes internal rechargeable batteries for energy that must be charged when not in use.
Key tips
- ·Never skip the daily/shift ready-check - a defibrillator found dead during a code is a real, repeated root-cause finding.
- ·Pads and batteries have real expiration dates - check them on every PM, not just at annual service.
- ·Verify energy-delivery accuracy with a real defibrillator analyzer, not just a self-test pass.
Typical Failure Modes
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
High-voltage capacitor failure
HighSymptoms: Charge fails or sluggish, low-energy delivery.
Root cause: Capacitor aging / leakage.
Battery degradation
HighSymptoms: Short charge-hold, low-battery on readiness test.
Root cause: Aged battery pack.
Charge / discharge relay fault
HighSymptoms: Won't charge or discharges unexpectedly.
Root cause: Relay/contactor wear.
SELV / patient isolation fault
MediumSymptoms: Leakage alarm, self-test fail.
Root cause: Failed isolation components.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Daily/shift visual and self-test check (AAMI EQ56 daily-ready standard)
- ·Battery and pad expiration-date tracking
- ·Energy-delivery accuracy test against a defibrillator analyzer
- ·Paddle/cable continuity check
- ·Annual full PM
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: High-voltage capacitor failure
- Confirm the presentation - typically charge fails or sluggish, low-energy delivery - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: capacitor aging / leakage.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the rechargeable battery pack per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.

- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the hV energy storage capacitor per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
Some defibrillators serviced between July 2023 through November 2025 were serviced without objective evidence that a Performance Inspection Procedure (PIP) was conducted, and the inability to perform the device's intended use may result in potential harms such as delays or inability to provide therapy.
- RECALL
Incorrect keypad was incorrectly installed onto a defibrillator/monitor.
- RECALL
Product shipped with incorrect IFU. IFU does not include proper cleaning/disinfection instructions
- RECALL
Their is a potential for battery pins to become loose within the defibrillator resulting in power issues.
- RECALL
Packaging of infant child reduced energy electrodes was not properly sealed.
- RECALL
The infant artwork on the product instructs incorrect pad placement. Also, the artwork is missing the Type BF Patient connection and High Voltage Warning symbols.
- RECALL
LIFEPAK CR Plus Automated External Defibrillators (AED) or LIFEPAK EXPRESS AED may fail to initiate voice prompts when the ON/OFF button is pressed and the lid is opened due to an internal component (reed switch) that can intermittently become fixed in the closed position. A defibrillator in this condition will fail to deliver a shock, with the potential result that therapy is not delivered and a patient is not resuscitated.
- RECALL
LIFEPAK CR Plus or LIFEPAK Express Automated External Defibrillators (AEDs) are recalled due to the potential to experience an early internal battery depletion issue.
- RECALL
Sterilization efficacy can not be confirmed for the current methods of sterilization listed in the product labeling.
- RECALL
This recall is being conducted due to the device being configured with the incorrect software for semi-automatic instead of fully automatic use. When the device is needed for a cardiac arrest emergency, the device will require that the user press the shock button instead of automatically delivering a shock as per the normal operation of the fully automatic device. Fully automatic defibrillators h
- RECALL
The device may not power on although it indicates it is ready for use and would not be able to provide defibrillation therapy.
