Project Description


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.



All Passy-Muir Valves have a closed position “No Leak” design that restores a closed respiratory system.






“No Leak” design maintains a column of air in the tracheostomy tube and redirects airflow and secretions up the trachea.





All other speaking valves have an open position design that causes air leakage during exhalation.




Years of evidence-based research has shown that the Passy-Muir Valve offers patients numerous clinical benefits beyond communication:

  • Restores positive airway pressure: The patented “No Leak” design of the Passy-Muir Valve and a closed system creates a more normal closed respiratory system, restoring positive airway pressure. This in turn promotes louder voice, improved swallow, stronger cough, and increased oxygenation.
  • Superior voice/speech production: Patients can produce clearer voice with more normal phrasing, better vocal quality and increased volume because all exhaled airflow is redirected up past the vocal cords.
  • Improves swallow, may reduce aspiration: The closed position “No Leak” design of the Passy-Muir Valve restores the patient to more normal physiology. This design facilitates increased pharyngeal/ laryngeal sensation and restores subglottic air pressure, which improves swallow and may reduce aspiration.
