      Abstract

      • 1.
        1. To delineate the effect of pCO2 and hydrogen ion concentration on the distribution of blood flow, the cardiac output, carotid, coronary, and renal flows have been measured in the following acid-base variations: respiratory acidosis and alkalosis, compensated (THAM) respiratory acidosis, and metabolic acidosis and alkalosis.
      • 2.
        2. Cardiac output, carotid flow, and coronary flow correlate directly with the carbon dioxide tension in the blood, irrespective of the hydrogen ion concentration.
      • 3.
        3. Renal blood flow varies inversely as the carbon dioxide tension, irrespective of the hydrogen ion concentration.
