Use of high-frequency jet ventilation to prevent aspiration in a patient with an uncuffed tracheostomy tube.
We report the use of high-frequency jet ventilation (HFJV) in a patient with an uncuffed tracheostomy tube who had significant pulmonary aspiration of upper-airway secretions. Respiratory secretions decreased during HFJV, indicating that the patient was no longer aspirating. Despite a continuous flow of gas out of the patient's nose and mouth, arterial blood gases remained within acceptable limits. We conclude that HFJV can prevent aspiration and maintain adequate ventilation when used with an uncuffed tracheostomy tube.
