Elective Use of the Ventrain for Upper Airway Obstruction during High Frequency Jet Ventilation

Abstract

Robert A Fearnley, Sheela Badiger, Richard J Oakley and Imran Ahmad

The success of high pressure source ventilation is entirely dependent upon upper airway patency to facilitate passive expiration and prevent increasing intrathoracic pressure and its associated deleterious sequelae. Distortions in airway anatomy may make passive expiration inadequate or impossible in some patients.
