Automatic external defibrillator (AED) LIFEPAK CR Plus and LIFEPAK EXPRESS – risk of failure to deliver a shock.

Manufactured by Physio-Control – risk of delay to defibrillation due to an intermittent component failure. Specific serial numbers are affected

Device details

The AED can be found in hospitals and in public places (eg railway stations, village halls and supermarkets).

Problem / background

LIFEPAK CR Plus AEDs or LIFEPAK EXPRESS AEDs may fail to initiate voice prompts when the ON/OFF button is pressed and the lid is opened. The problem is 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.


  • Ensure that all those responsible for the AED follow the instructions in the manufacturer’s Field Safety Notice FSN
  • To check if your AED is affected call Physio-Control customer support or visit their website and go to ‘Search Affected Devices’ and enter the serial numbers.
  • If the AED is faulty, remove the unit from service and contact Physio-Control to arrange for it to be corrected.
  • If you have already acted on this FSN, no further action is required.
