Popis:	The monitoring and control of anaesthetic gases during a surgical procedure is of critical importance to patient welfare. This work describes the initial investigation of coatings and calibration of coated quartz piezoelectric crystals for N 2 O, halothane and enflurane. Once the crystals and coatings were characterised, they were incorporated into a prototype feed-back controller which allowed the required gas concentration to be present. Fluctuations outside preset alarm thresholds were indicated by means of an alarm and corrected automatically.
