Anaesthesia for bronchoscopy. A laboratory study using the Nuffield lung ventilator with the injector technique.
The control module of the Nuffield (A-P) Anaesthetic Ventilator was found to be an efficient means of automatically controlling the ventilation of the lungs through a bronchoscope during a series of laboratory experiments. The relationships between lung characteristics (compliance and airway resistance) and the driving flow rate through various injectors on the final oxygen concentrations and tidal volumes delivered were determined. A 14 gauge injector provided the largest tidal volumes with the least entrainment of air.
