The PM-APF15 provides bacterial and viral filtration efficiency of >99.9%, effectively filtering out >99% of all airborne particulates.
The device may be used by non-mechanically ventilated tracheostomy pediatric and adult patients. The device should NOT be used by infants, neonates, and patients who require humidification, or patients who are on any form of mechanical ventilation. Made in the USA.
What is a Passy Muir Valve?
Invented by a patient named David Muir, the Passy Muir Valve is a simple medical device used by tracheostomy and ventilator patients. When placed on the hub of a tracheostomy tube or in-line with the ventilator circuit, the Passy Muir Valve redirects airflow 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 swallow, and secretion management.
No-Leak Design
The patented no-leak design of the Passy Muir Valve means that the Valve is always in a closed position until the patient inhales. The Valve opens easily with less than normal inspiratory pressures and closes automatically at the end of the inspiratory cycle without air leak and without patient expiratory effort.
Closed System
Unlike open position speaking valves, the bias-closed position Passy Muir Valve allows the patient to create positive airway pressure and restores the patient to a more normal closed respiratory system. The closed system also creates a protective column of air in the tracheostomy tube which resists secretions from moving up the tube and occluding the Valve. Instead, secretions may be coughed up around the tube and expectorated or suctioned from the mouth.
All Passy Muir Valves have a bias-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.

Benefits of the Passy Muir Valve
Restores Positive Airway Pressure
The bias-closed position, no-leak Passy Muir Valve design restores a more normal closed respiratory system, which allows the patient to create positive airway pressure without the need for manual occlusion of the tracheostomy tube. This promotes louder voice, improved swallow, stronger cough, and may increase oxygenation.
Superior Voice/Speech Production
Tracheostomized and ventilator-dependent patients can produce clearer voices with more normal phrasing, better vocal quality, and increased volume because all exhaled airflow is redirected up past the vocal folds.
Improves Swallow & May Reduce Aspiration
The bias-closed position, no-leak design of the Passy Muir Valve can improve the safety and efficiency of swallowing and may reduce aspiration. The bias-closed position Valve restores the patient to a more normal closed system which facilitates increased pharyngeal and laryngeal sensation and restores positive subglottic air pressure.
Restores Subglottic Pressure
Only the bias-closed position, no-leak design of the Passy Muir Valve reestablishes a closed respiratory system and restores subglottic pressure, which improves swallowing and may reduce aspiration.
In-Line Ventilator Use
Adult, pediatric, and neonatal patients on the ventilator may utilize the Passy Muir Valve during mechanical ventilation. All Passy Muir Valves are interchangeable (except the PMV 2020) and can be used both on or off acute-care and portable ventilators.
Facilitates Weaning
Passy Muir Valves are used as an augmentative tool for weaning patients from the ventilator as it reestablishes physiologic PEEP, which in turn may improve oxygenation. As the patient becomes accustomed to exhaling through the upper airway, patient confidence is improved and respiratory muscle retraining is facilitated.
Reduces Decannulation Time
Passy Muir Valves may be used as an interim step in the decannulation process by allowing the patient to begin to adjust to a more normal breathing pattern through the upper airway on exhalation. This allows the patient to gain confidence and the physician to assess for airway patency and can significantly shorten the decannulation process.
May Improve Oxygenation
The bias-closed position, no-leak design of the Passy Muir Valves restores a more normal closed respiratory system. As a result, Positive End Expiratory Pressure (PEEP) is reestablished which may facilitate improved oxygenation.
Improves Olfaction
Passy Muir Valves improve the sense of smell by re-establishing airflow through the oral and nasal cavities during exhalation. This improved sense of smell may lead to an increase in sense of taste, appetite, and caloric intake, which are all important in the recovery process.
Facilitates Secretion Management
The bias-closed position, no-leak design of the Passy Muir Valve facilitates secretion management as it re-establishes a closed system that enables the patient to produce a stronger, more effective cough and improves swallowing due to restored positive subglottic pressure. It also facilitates evaporation of secretions due to the redirection of air through the upper airway during exhalation. As a result, suctioning needs may be reduced.
Facilitates Infection Control
The Passy Muir Valve eliminates the need for finger occlusion of the tracheostomy tube, which may help prevent infection and offers protection from particulates entering the trachea. The Passy Muir Valve redirects secretions through the upper airway, allowing oral expectoration and reducing contamination of the patient’s immediate environment.
Interchangeability Between Tracheostomy and Ventilator Use
All Passy Muir Valves, except the PMV 2020, can be used both on and off the ventilator with both pediatric and adult patients. This includes patients with a tracheostomy only, patients who are weaning from the ventilator, and patients who are ventilator-dependent. The Passy Muir Valves can be placed in-line with the ventilator using disposable tubing (with PMV 007 only) or with the PMV-AD22 Flexible Silicone Adapter (with PMV 005, PMV 007, PMV 2000 and PMV 2001).
