Abstract
One of the problems of using anesthesia in conflict areas is the difficulty of obtaining oxygen for medical usage. One solution for this problem is to use an oxygen concentrator and an air compressor. In this report, we examined an oxygen concentrator and an air compressor which are available in Japan. Connecting them with three different anesthetic machines, we measured what concentration and flow of oxygen they could produce.
Though the oxygen concentrator itself did not produce a high flow of gas, the combined use of an air compressor and an oxygen concentrator proved to provide a gas flow rate of more than 6l•min-1, and an oxygen concentration of more than 45% with any make of anesthetic machines. The combined use of an oxygen concentrator and an air compressor with an anesthetic machine, is a practical method of administering anesthesia in conflict areas.
