Energy Expended in Administering Artificial Respiration

Abstract

Five methods of artificial respiration were studied: prone-pressure (Schafer), arm-lift back-pressure (Nielsen), arm-lift chest-pressure (Silvester), hip-roll prone-pressure, hip-lift. 10 male and 10 female operators were used. "Victims" were 4 males and 4 females. Oxygen consumption was measured in a closed system. The amt. of oxygen used/min. at a rate of 12 respirations/min. was: For men, prone-pressure, 547 cc; arm-lift chest-pressure, 706 cc; arm-lift backpressure, 947 cc; hip-roll prone-pressure, 1045 cc; hip-lift, 1050 cc. For women, prone-pressure, 445 cc; arm-lift chest-pressure, 480 cc; arm-lift back-pressure, 657 cc; hip-lift, 713 cc; hip-roll prone-pressure, 746 cc.
