Anaesthesia 1984;39:938-9. Modern anaesthesia machines. Modern anesthesia delivery systems incorporate the following functional components: gas mixing device, breathing circuit, ventilator, waste gas scavenger system, and patient and system monitors. For removable vaporizers, a slide lever makes a shaft engage a hole on the dial of the unused vaporizer and immobilises it. Loss of anesthetic gases due to defective safety equipment. Anesthesiology 1984;60:342-6. 5 th ed. Anesthesia Machine — Safety Features See online here There have been remarkable improvements in the drugs, techniques and anesthesia machines being used.

Inadvertent administration of 100% oxygen during anaesthesia. Ritchie PA, Cheshire MA, Pearce NH. Disconnect central gas supply hose for O 2. Contin Educ Anaesth Crit Care Pain 2006;6:75-8. As a result, anesthesia is a safer procedure today. Dudley M, Walsh E. Oxygen loss from rotameter. Very few models of vaporizers have a safety mechanism whereby they work properly despite reversal of gas flow through them. Incorporation of safety features in anaesthesia machines and ensuring that a proper check of the machine is done before use on a patient ensures patient safety. 7. The new safety features allow the dilution of oxygen in the breathing mixture, following a lack in the low-pressure system. The establishment of the Anesthesia Patient Safety Foundation (APSF) in the USA was a notable milestone in this journey. [Last accessed on 2013 Sep 3]. In: The Anesthesia Machine.

Incorporation of safety features in anesthesia machines and ensuring that a proper check of the machine is performed before use on a patient ensures patient safety. Tubes are made leak-proof with neoprene washers (O-rings) at both ends of the flow meter assembly. Olympio MA. The safety features were gradually incorporated into the anesthesia machine over the years following problems and mishaps. This review will trace all the present safety features in the machine and their evolution. 11.
