Abstract
Measurements were made of the arterial-alveolar carbon dioxide gradient in anesthetized dogs at body temperatures ranging from normal down to 16°C. Pulmonary diffusing capacity was determined by a steady-state carbon monoxide method in anesthetized dogs at normal body temperatures and at 25°C. From the results it is concluded that although diffusing capacity is reduced at low body temperatures, it is still adequate for transfer of both CO2 and O2 because the metabolic requirements for gas exchange are also reduced.Keywords
