Abstract
1. A method is described for measuring tissue oxidation under reduced barometric pressure. 2. The oxygen uptake of yeast is diminished by low barometric pressures to a greater extent than by a reduction of the partial pressure of oxygen, to a corresponding degree, at atmospheric pressure. 3. This effect of low pressure is not observed with certain in vitro oxidation systems. 4. The anaerobic respiration (carbon dioxide production) of yeast is not at all affected by low pressures. 5. The inhibition of tissue oxidation caused by carbon monoxide is removed by lowering the pressure.
