Four subjects hyperventilated at three carefully controlled alveolar ventilation levels. It was found that carbon dioxide excretion and the rate of change of alveolar carbon dioxide tension were related to the alveolar ventilation. Three exponential components were recognized in the carbon dioxide excretion curves and their time constants determined. These were related to the body stores from which carbon dioxide was removed. The slope of the whole body carbon dioxide dissociation curve was found to be related to the alveolar ventilation level and ranged from 1·17–2·03 ml./mm. Hg./min,
