Passy Muir speaking valve
Passy Muir speaking valve is a common type of one-way speaking valve, allowing patients to speak post-tracheostomy placement. They are used in both adults and children . With the valve in situ, the patient is able to inhale air normally into the lungs but on exhalation the valve closes and air can flow over the vocal folds permitting speech to occur.
Additional benefits of valve placement
Research shows that speaking valves provide much improved quality of life post-tracheostomy:
- reduced risk of aspiration and chest infections
- greater protection of the upper airway
- improved deglutition
- better sense of taste and smell
