Passy-Muir Valve

  • The Passy-Muir valve permits inspiration but not exhalation via the tracheostomy tube and, when the trach cuff is deflated, exhaled air is thus directed up through the glottis, permitting phonation
  • The Passy-Muir valve is usually well-tolerated and can be used in patients with neuromuscular disease

  • Requirements for Passy-Muir Valve Use:

    • Ability to Clear Secretions:
    • Adequate Gas Exchange:
    • Hemodynamic Stability:
    • Normal Mental Status:
  • Advantages of Passy-Muir Valve:

    • Aspiration During Eating is Reduced: as it restores more normal subglottic and glottic airflow during exhalation
    • Decrease in Amount of Bronchial and Pharyngeal Secretions: because air escaping through the mouth and nose contributes to their evaporation
    • Improved Cough Effectiveness: because of the restoration of glottic function
    • Reestablishment of the Ability to Smell:
  • Complications of Passy-Muir Valve:

    • Inappropriate use of excessively large trach -> impedes expiratory airflow through trachea
    • Accidental use with trach with cuff still inflated -> completely obstructs expiratory airflow
