During ambulation, which feature may allow speech for a patient with a tracheostomy?

• A. Passy-Muir valve
• B. Nasal cannula
• C. Chest tube
• D. Wound VAC

Answer: (A)

A device that acts as a one-way valve on the tracheostomy tube enables speech by redirecting exhaled air up through the vocal cords. This is the Passy-Muir valve. It remains closed during exhalation so air doesn’t escape through the tracheostomy; instead, it is forced to travel upward through the larynx, mouth, and nose, producing voice. On inhalation, the valve opens to allow air into the lungs through the tracheostomy tube. This setup makes speaking possible even with a tracheostomy, which is especially helpful during activities like ambulation where communication is important. The other options don’t provide this function: a nasal cannula delivers oxygen but doesn’t enable phonation; a chest tube drains the pleural space; a wound VAC is used for wound management.
