The pulmonary responses of 88 pregnant women were compared to those of 39 nonpregnant control subjects during different exercise intensities. At rest the pregnant women had higher tidal volumes, oxygen consumption, carbon dioxide production, and respiratory exchange ratio. With increased work loads the pregnant volunteers have consistently lagged behind the nonpregnant control subjects for every parameter, which indicates a decrease in pulmonary reserve and inability to exercise anaerobically.
在不同运动强度下，对88名孕妇和39名非孕对照受试者的肺部反应进行了比较。休息时，孕妇的潮气量、耗氧量、二氧化碳产生量和呼吸交换率较高。随着工作量的增加，在每个参数上，怀孕志愿者始终落后于非孕对照受试者，这表明肺部储备能力下降，无法进行无氧运动。
