High-frequency jet ventilation during bronchoscopy in a dog

A dog with severe pulmonary disease caused by Filaroides osleri (Oslerus osleri) infection was anesthetized with thiopental sodium IV for diagnostic bronchoscopy. The dog was ventilated continuously during bronchoscopy with a high-frequency jet ventilator (using a rate of 100 breaths/min, drive pressure of 20 psi, and inspiratory fraction of 0.30). High-frequency jet ventilation provided satisfactory ventilatory support during bronchoscopy despite the dog's pulmonary disease.
