Effects of Respiratory Alkalosis on Oxygen Consumption and Oxygenation

Abstract

The effect of respiratory alkalosis on oxygen consumption after passive hyperventilation was studied in eight dogs. PaCo2 decreased from 32.1 to 13.6 torr, pH increased from 7.43 to 7.72, and oxygen consumption increased from 116.5 to 147.5 ml/m2/min. Venous admixture decreased from 17.1 to 8.8 per
