Over the last two decades, there has been an explosion of interest in mountain pursuits, and doctors face new challenges in dealing with the changes in human physiology and particular medical conditions that arise from exposure to altitude and cold. The three authors are experienced mountaineering physicians who have dealt with illness and accidents in high places and who are known and respected internationally for their academic research in the field. The book will be invaluable reading for any doctor accompanying an exhibition to high altitude and also of interest to physicians and physiologists studying our dependence on oxygen and the ingenious physiological adjustments that allow us to live in the cold, thin air of high mountains. Building on the success and reputation of earlier editions, and incorporating the considerable advances that have occurred since the previous edition published in 1994, the third edition will establish this text as the definitive reference on high altitude medicine and physiology.
