- the Pitt Speaking Tube
- the facilitation of speaking in the tracheostomized patient
- non-fenestrated, cuff tube for continuous mechanical ventilation and airway protection with a port to direct airflow above the cuff to the larynx.
- when airflow directed through the larynx some patient are able to vocalize
- there is a tiny separate catheter running in a channel in the wall of the tracheostomy which opens on the cephalo-dorsal aspect of the tube -> proximal to the cuff.
- external aspect of the catheter is connected to a pressurized gas source
METHOD OF INSERTION
- see insertion of a tracheostomy
- controlled airflow is delivered to above the cuff -> allow patient to vocalise
