Fiberoptic bronchoscopy with general anesthesia using a transvector for ventilation

A transvector, a highly efficient flow amplifier, until present in use only in industry, has been adapted to the ventilation of patients during fiberoptic bronchoscopy under intravenous general anesthesia. The transvector is connected directly to an endotracheal or tracheostomy tube and provides an open unobstructed passage of the instrument into the patient's airways. The method combines safety with ease of instrumentation and uniformly satisfactory ventilation has been obtained in 25 patients.
