Measurements of Volatile Gases
When using potent inhalation anaesthetics such as halothane, enflurane or isoflurane, it is important to have a precise control of the exact anaesthetic concentration inhaled by the patient. The first imperative is, of course, to use a modern and carefully calibrated vaporizer. The Cyprane vaporizers and the Dräger vaporizers are the most frequently used in Western Europe. However, after a certain time deviations and even major deviations from the dial setting are possible and regular maintenance and calibration are mandatory.
