Passy Muir believe that communication is the essence of the human spirit; it is essential to individual rights and dignity. They are committed in their efforts to offer tracheostomized and ventilator-dependent patients a step towards independence and dignity through speech.


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:
  • Voice/Speech Production
  • Improved swallowing
  • Secretion management
  • Oxygenation
  • Restores positive airway pressure
  • In-line Ventilator Use & Interchangeability
  • Weaning
  • Decannulation
  • Olfaction
  • Infection Control
  • Pediatric Speech/Language Development
  • Quality of Life 

All Passy Muir® Valves have the patented closed position “no leak” design, are designed to easily attach to the universal 15mm hub of tracheostomy tubes including neonatal and pediatric tubes, and can be used interchangeably by tracheostomized and ventilator dependent patients with the exception of the PMV® 2020. All Passy Muir products are latex free and made in the USA.
