Respiration at High Altitudes *
It has been clearly recognized that a low barometric pressure, when first encountered, may interfere with the normal workings of the human machine, but that later by compensatory responses the body may become adapted to the new conditions. The outstanding variable encountered in ascents to high altitudes by airplane, dirigible, free balloon, or mountaineering is the tenuousness of the atmospher...
