The cardiovascular effects of carbon dioxide in man awake and during diethyl ether anesthesia

Abstract:

The cardiovascular responses of human volunteers to several inspired concentrations of carbon dioxide during anesthesia with 3 and 4.5% ether are described. At 3% ether, the slopes for CO2 vs. heart rate and cardiac output were decreased from slopes for awake values. At 4.5% ether, the slopes for CO2 vs. central venous pressure and total peripheral resistance were increased and that for heart rate decreased from slopes for awake values. At 4.5% ether the slopes for CO2 vs. cardiac output, stroke volume, and total peripheral resistance were significantly elevated over those at 3% ether. All other values at both 3 and 4.5% ether were unchanged from awake values.
