Abstract
Six conscious dogs were exposed for 30 min to 6% carbon dioxide (PCO2 45 mm Hg) at ambient atmospheric pressure and oxygen tension in an environmental chamber. Mean cardiac output fell from a control of 194 to 170 ml/min per kg during the first 3 min of exposure. Heart rate also fell but stroke volume was unaltered. Right atrial pressure, left atrial pressure, and pulmonary artery pressure rose; systemic arterial pressure, pulmonary vascular resistance, and systemic vascular resistance did not change. The bradycardia persisted but all pressures and cardiac output were not significantly differrent from the control by the end of the experimental period.
