Shiley Phonate Speaking Valve enables easier vocalization for alert, awake tracheostomy patients who can breathe independently without assisted mechanical ventilation. It connects to the tracheostomy tube and directs airflow through the vocal cords to facilitate speech. Directing airflow past the oral and nasal chambers also helps decrease secretions and improves swallowing and sense of smell. Shiley Speaking Valve permits easier vocalization without finger occlusion, preventing hygiene and infection concerns.
