Acute hypercapnia increases the oxygen-carrying capacity of the blood in ventilated dogs

Abstract

Permissive hypercapnia due to inhaled CO2 increases oxygen-carrying capacity in dogs. The PaO2 remains at normal range even at a PiCO2 of 75 torr (10 kPa). The benefits of these effects during permissive hypercapnia, due to controlled hypoventilation, warrants investigation.
