Abstract : Rates of pulmonary ventilation, relative durations of inspiration and expiration, and peak inspiratory rates were measured in a number of individuals at rest and during mild exercise. In a group of ten subjects having an average weight of 147.4 pounds the average minute volume was 8.16 liters. In another group of ten subjects having an average weight of 158 pounds the following averages for the group were obtained: at rest; minute volume 9.45 liters; peak inspiratory rate 34 liters per minute; inspiration 34.9% of total cycle; and a ratio between peak inspiratory rate and minute volume of 3.6. During mild exercise the averages for the same group were: minute volume 15.7 liters; peak inspiratory rate 58.4 liters per minute; inspiration 40.07% of total cycle; and a ratio between peak inspiratory rate and minute volume of 3.7. Rate of flow records obtained while a group of ten subjects received oxygen from a multiple place manifold were analyzed to ascertain frequencies of occurrence of various multiples of the average peak inspiratory rate.
