One hundred and fifty patients were ventilated artificially during bronchoscopy using a Bird Mark 2 ventilator with either oxygen or a nitrous oxide in oxygen mixture as the driving gas. Satisfactory conditions for the examination were achieved. There was no significant deterioration in PaO2 or PaCO2.
Theoretical considerations of closed circuit anaesthesia using oxygen and halothane are examined. Clinical experience has confirmed the value of the Narcotest as a reliable in-line monitor of inspired halothane concentration, while the use of an oxygen analyser is a desirable adjunct. The advantages of economy and elimination of theatre pollution are discussed.
