The Use of the Hayek Oscillator to Produce Postoperative Hyperventilation<br />
in the Neurosurgical Patient<br />
Dr. A. Bristow FFARCS<br />
Consultant Anaesthetist, St. Bartholomews Hospital, London<br />
Twelve ASA I patients undergoing elective craniotomy were given a standardised anaesthetic.<br />
Immediately after extubation at the end of the operation, the [Hayek] Oscillator was attached to the<br />
patients.<br />
There was a significant rise in PaO 2<br />
and a significant reduction in PaCO 2<br />
to the range 3.3 -4KPa. There were no signs of airway obstruction, and all<br />
patients found the Oscillator comfortable.<br />
