Basal oxygen uptake of man at high altitude

Abstract

When man native to low altitude is exposed to altitudes in excess of 10,000 ft, is there a change in his basal oxygen uptake? This question was prompted by the unexpected observation of a 20% decrease in resting oxygen uptake of cattle and lambs at high altitude. To elucidate this problem in man, multiple determinations of basal oxygen uptake were made on six individuals, at both 5,200 and 14,150 ft. A small but significant increase in oxygen uptake was observed, probably reflecting the energy required to increase ventilation. Note: With the Technical Assistance of Estelle B. Grover and Janet K.
