Title: Oxygen administration in diving accidents.
Author: Komesaroff, D
Abstract: Oxygen administration in diving accidents has been well documented.1 However the importance of duration of oxygen supply, humidification and temperature of inspired oxygen and pain relief has often been overlooked. Basal (resting) physiological oxygen requirements of an adult are approximately 250 ml/min (3 ml/kg). Activity, body temperature and the presence of pain increase this. 2 l/min is about the maximum possible oxygen utilization (measured in athletes following a 100 m sprint). In demand valve resuscitators, high flow rates of oxygen are used to flush the exhaled carbon dioxide to the atmosphere. This has several disadvantages. Approximately 10 l/min of oxygen are required. The inhaled oxygen is dry and cold. Sterilization of equipment after use is inconvenient or impossible. In closed circuit resuscitation systems less oxygen is used as expired carbon dioxide is removed by an absorbent, for example soda lime or baralyme.
