Reason for Updates to Use Instructions

ZOLL Medical Corporation is updating use instructions for 731 ventilators due to Magnetic Resonance Imaging (MRI) safety information in the labeling, that may lead to misuse and ventilator failure. The Operator’s Guide and Quick Reference Guide (QRG) include information on how far the ventilator should be placed from the MRI machine based on the magnetic field strength. However, a review found that some important details were accidentally left out of these guides. This missing information might lead users to place the ventilator too close to the MRI machine, which could cause the ventilator to trigger alarms, device malfunction or unexpectedly shut down.

The use of affected product may cause serious adverse health consequences, including lack of oxygen, difficulty breathing, organ damage, and death.

There have been no reported injuries. There have been no reports of death.
