The total lung capacity (TLC) and its subdivisions along with the forced spirometric values (FEF25-75 and FEV1) were determined in a group of 44 healthy subjects, composed of 29 women and 15 men. The determinations were carried out in a sitting position and in supine position, breathing air. All the pulmonary volumes diminished when the subject lay down, but the functional residual capacity (FRC) was that which underwent a greater reduction. The residual volume decrease was the only one which did not reach statistically significant levels. Women always showed smaller pulmonary volumes than men. It has been demonstrated that FRC can be exactly measured by means of the closed helium technique. The regression figures of FRC in supine position were determinted for both sexes, with a r = 0,33 (p less than 0,1) in women and r = 0,95 (p less than 0.001) in men. The forced spirometric tests did not undergo any important changes although the reduction of the FEV1 was significant in both sexes. The results obtained were compared with those published by other authors.
在一组由29名女性和15名男性组成的44名健康受试者中，测定了肺总量（TLC）及其细分部分以及用力肺活量值（FEF25 - 75和FEV1）。测定在坐位和仰卧位呼吸空气时进行。当受试者躺下时，所有肺容积均减小，但功能残气量（FRC）减小幅度更大。残气量的减少是唯一未达到统计学显著水平的。女性的肺容积总是比男性小。已经证明，FRC可以通过闭合氦气技术准确测量。确定了男女仰卧位FRC的回归系数，女性r = 0.33（p < 0.1），男性r = 0.95（p < 0.001）。尽管FEV1的降低在男女中均显著，但用力肺活量测试未发生任何重要变化。将所得结果与其他作者发表的结果进行了比较。
