FDA Safety Communication- ZOLL LiveVest 4000

The FDA approved a new software for the  ZOLL LifeVest 4000 for patient alerts when a “Call for service – Message Code 102” is displayed. The potential hazard of the device failing to deliver treatment to a patient if the device is not replaced soon after displaying a “Call for service – Message Code 102” was previously described in the January 17, 2018 FDA Safety Communication and an update on July 25, 2018.

On January 17, 2018, the U.S. Food and Drug Administration issued a safety communication for the ZOLL LifeVest 4000, which may fail to deliver appropriate therapy if the device shows the following error message:

“Call for service: Device has a problem that may require service. Call ZOLL for service, Message Code 102.”

Failure to contact ZOLL and immediately replace the device after Message Code 102 appears on the device screen may result in serious patient harm or death because the device may fail to deliver therapy appropriately when needed. To date, FDA is aware of one U.S. patient death due to the LifeVest’s failure to deliver treatment as expected after Message Code 102 was displayed.
