On the Influence of Carbon Dioxide Inhalation upon the Intermediate Carbohydrate and Water Metabolism

Abstract

In man, inhalation of an air containing 5.3-6.8% CO₂ for 5-7 minutes is followed by increase in the blood sugar content and decrease in the lactic acid content.
Haemoglobin content is not changed or tends to be diminished, so that the blood concentration has tendency to dilution or does not undergo any appreciable modification. Serum-protein content is lessened in the majority of cases, but is sometimes augmented, its variation not running parallel to that in the haemoglobin content. Sodium chloride content in serum varies only slightly and irregularly.
Attempts are made to account for these changes in the blood being brought about through CO₂ inhalation.
