Jet ventilation for fiberoptic bronchoscopy under general anesthesia.
An oxygen jet method ventilating patients during laryngoscopy has been applied to fiberoptic bronchoscopy. A 3.5 mm plastic tube 24.5 cm long was inserted into the trachea through the mouth. An intermittent jet of oxygen at 3.5 atm (50 psi) was applied to this tube using a 1.5 mm ID plastic catheter to ventilate the patient. ⋯ The high PO2 levels were maintained even during suctioning. General anesthesia for fiberoptic bronchoscopy can be performed using an endotracheal tube not smaller than 8 mm internal diameter (ID). The advantages of the oxygen jet technique are that it can be used in smaller patients and that the upper airway can be examined.
