[Posted 10/16/2012]

AUDIENCE: Anesthesiology, Dentistry, Risk Manager

ISSUE: Accutron voluntarily recalled the product after learning through two customer complaints that the flowmeter was flowing nitrous oxide gas without any oxygen gas flow. When not mixed with oxygen, inhaling nitrous oxide can lead to temporary and permanent brain damage and death.

BACKGROUND: The Ultra PC% flowmeter is used to control the flow of gases used in nitrous oxide-oxygen sedation systems. Nitrous oxide-oxygen sedation systems are used to sedate patients during certain dental procedures. The company has reported that two complaints have been received for this flowmeter defect, however, no injuries have been reported to date.

RECOMMENDATION: Consumers with the affected flowmeters should stop using and return the flowmeters to Accutron for a free replacement. The company notified distributors and customers of this recall by mail and is arranging for return and replacement of all recalled products.
