Invented by a patient named David Muir, the Passy-Muir^® Tracheostomy & Ventilator Swallowing and Speaking Valve is a simple medical device used by tracheostomy and ventilator patients. When placed on the hub of the tracheostomy tube or in-line with the ventilator circuit, the Passy-Muir Valve redirects air flow through the vocal folds, mouth and nose enabling voice and improved communication. Years of evidence-based research has shown that the Passy-Muir Valve offers patients numerous clinical benefits beyond communication, including:

• Improved swallowing
• Secretion management
• Oxygenation
