Peak Rates of Oxygen Flow from Oxygen Supply Systems.
Abstract
Maximum rates of flow of oxygen required by a group of 10 men supplied from a single system were determined for conditions of rest and moderate exercise. Under the conditions indicated, maximum rates of flow were as follows: (1) rest, random group breathing, 141 liters per minute. (2) rest, rhythmic group breathing, 220 liters per minute. (3) exercise, random group breathing, 415 liters per minute. (4) exercise, rhythmic group breathing, 445 liters per minute. Respiratory minute volumes during exercise were determined on individual subjects receiving oxygen from systems capable of maximum rates of flow of 52 and 75 liters per minute respectively. With a mean minute volume of 19.2 liters per minute, the ratio, maximum rate of flow divided by minute volume (M.F./M.V.) was found to be 2.8 when determined on 19 subjects. With a mean minute volume of 29.6 liters per minute, M.F./M.V. was found to be 2.6 when determined on 11 subjects. (Author)
