Accutron's Ultra PC% cabinet mount flowmeters may leak nitrous oxide when the oxygen flow is switched off, possibly leading to brain damage in patients.

Accutron recalled 206 units of its Ultra PC% cabinet mount flowmeters after receiving 2 reports that the devices leaked nitrous oxide after the oxygen flow was switched off.

When not accompanied by oxygen, the stream of nitrous oxide gas could cause brain damage in patients, the company noted.

The recall includes 8 product models and customers can return these flowmeters for free replacement, according to an FDA notice.
