BREATHING MEASUREMENTS ON NORMAL NEWBORN INFANTS

Abstract

Plethysmograph measurements made on 74 infants, 47 sleeping, indicate that the method is practical and accurate as applied to the newborn, and also that the degree of gradual day-to-day lung expansion cannot be estimated satisfactorily if only a few measurements of this rate of breathing and minute volume are taken into consideration, since these vary widely from day to day.
