Abstract : Measurements of peak rates of flow during random breathing were made on groups of one, two, five and 10 subjects, at rest and during mild exercise. The results were as follows: (A) At rest: one subject 30 liters per minute: two subjects, 58 liters per minute: five subjects, 100 liters per minute; ten subjects, 260 liters, per minute. (B) During mild exercise: one subject, 58 liters per minute; two subjects, 130 liters per minute; five subjects, 270 liters per minute; ten subjects, 490 liters per minute. Maximum peak rates attained during intentional simultaneous inspirations by all members of the groups were as follows: (A) At rest: five subjects, 158 liters per minute; ten subjects, 480 liters per minute. (B) During mild exercise: two subjects, 167 liters per minute; five subjects, 335 liters per minute; ten subjects 675 liters per minute. Peak rates during random breathing by groups of subjects were lower by significant amounts than the theoretical maximum rates required during intentional simultaneous inspirations. (Author)
