Vyaire Medical has provided on update on a “field correction” for its bellavista ventilators, urging customers to disable a specific data communication setting because it puts the ventilators at risk of shutting down and generating a technical failure alarm.

The problem affects bellavista 1000 and 1000e ventilators that have software version 6.0.1600.0 or higher installed. The affected ventilators were distributed to medical facilities in numerous U.S. states from March 21, 2019, to Dec. 23, 2021.

Vyaire Medical said it has received complaints of the failure happening, requiring the ventilators to be rebooted. The company said there were no reports of patients being harmed.
