Anaesthetic risk associated with tracheostomy speaking valve

A recent SCIDUA case has prompted this safety alert regarding the Passy Muir Speaking Valve (PMSV) in which a patient death was directly attributable to this piece of equipment.

The PMSV is the most commonly used speaking valve for tracheostomy and ventilator-dependent patients. It can be mistaken for a filter and can connect directly to the anaesthetic circuit.

Anaesthetists commonly encounter patients with tracheostomies, and knowledge about the existence and functioning of this valve is essential.

SCIDUA has developed this Tracheostomy Alert Information Sheet with clinical recommendations.
