✦ Synopsis

The momtormg and control of anaesthetlc gases durmg a surgical procedure IS of crlttcal Importance to patlent welfare Tins work describes the mltlal mvestlgatlon of coatmg and cahbratlon of coated quartz plezoelectnc crystals for N,O, halothane and enflurane Once the crystals and coatmgs were charactensed, they were Incorporated mto a prototype feed-back controller which allowed the reqmred gas concentration to be preset Fluctuations outslde preset alarm thresholds were mdlcated by means of an alarm and corrected automatically Keywords Plezoelectrlc sensors, AnaesthetIc gas momtonng, Crystals (plezoelectrrc)
