The Effect of High Concentrations of Carbon Dioxide on Blood Serotonin Levels in Man. Chronic Hypercapnia

摘要

Whole blood serotonin levels in young men were investigated during exposure to a 4% carbon dioxide environment (PICO2 = 29.9 mm. Hg) for a 10-day period. No significant change in serotonin levels was found in those men acting as outside controls at ambient (0.03%) carbon dioxide, but there was a 34.0% decrease (P
