Vocalisation via a cuffed tracheostomy tube.

Preliminary report of laryngeal phonation during mechanical ventilation via a new cuffed tracheostomy tube.

OBJECTIVE To study the safety, efficacy, patient tolerance, and patient satisfaction of the Blom Tracheostomy Tube and Speech Cannula (Pulmodyne, Indianapolis, Indiana), a new device that allows the patient to speak while the tracheostomy tube cuff is fully inflated. METHODS With 10 tracheostomized mechanically ventilated patients we recorded ventilator settings and physiologic variables at b...

A Broken Metallic Tracheostomy Tube

Albuterol delivery via tracheostomy tube.

HYPOTHESIS Albuterol delivery through a tracheostomy tube is affected by device (nebulizer vs metered-dose inhaler), interface (mask vs T-piece), bias flow, and humidification. METHODS A lift bar was placed between the chambers of a dual-chambered lung model such that a ventilator triggered simulated spontaneous breathing at a rate of 20 breaths/min, tidal volume of 0.4 L, and inspiratory-exp...

Pathogenesis of tracheal stenosis following tracheostomy with a cuffed tube. An experimental study in dogs.

A manometric study of the upper oesophagus in the dog following cuffed-tube tracheostomy.

Intraluminal oesophageal pressures were measured in dogs after tracheostomy and intubation with either uncuffed or cuffed tracheostomy tubes. Possible explanations for disordered swallowing following tracheostomy were found in those animals intubated with cuffed tracheostomy tubes: (a) Increased intraluminal pressures were measured in the oesophagus at the level of the cuffs. (b) Significantly ...
