Abstract
Moderate elevations of pCO2 (61–75 mm Hg) did not consistently depress myocardial contractility as determined by standard ventricular function curves. With an altered preparation in which heart rate and left atrial pressure were held constant, a pCO2 of 60–75 mm Hg was accompanied by an average reduction in stroke work to 73.6% of its control value, while hypocapnia with an alveolar pCO2 of 6–13 mm Hg was unaccompanied by any consistent reduction in stroke work.
