根据胸腔和腹部对潮气量的不同贡献，应用呼吸感应体积计对20名健康儿童进行了评价。该方法的准确性是通过在站立、坐着、仰卧、左侧卧位和俯卧姿势下用气体测速仪同时测量潮气量来确定的。这两种技术的比较显示，在所研究的所有体位中，平均相关系数大于0.96，平均斜率在0.98至1.11之间，平均SEE小于8%。通过连接到气体测定仪的口罩呼吸，呼吸模式发生了实质性的变化，潮气量平均增加了32%(P<；0.05)。在站姿和坐姿中，胸腔对潮气量的贡献占主导地位(65%)，而在卧位中腹部贡献占主导地位(>；61%)。结论：RIP是一种准确测量儿童呼吸机通气量的方法，避免了使用常规呼吸测量仪所带来的伪影。
A new technique to measure ventilation, based on the separate contributions of rib cage and abdomento tidal volume, the respiratory inductive plethysmograph was evaluated in 20 healthy children. The accuracy of the method was determined by simultaneously measuring tidal volume with a pneumotachograph in the standing, sitting, supine, left lateral decubitus, and prone postures. Comparison of these two techniques showed mean correlation coefficients greater than 0.96, mean slopes between 0.98 and 1.11, and mean SEE of less than 8% in all postures studied. Breathing through a mouthpiece connected to a pneumotachograph resulted in a substantial change in the pattern of breathing and a mean increase in tidal volume of 32% (P<0.05). In the standing and sitting postures, rib cage contribution to tidal volume was predominant (>65%) whereas in the recumbent postures abdominal contribution was predominant (>61%). We conclude that the RIP is an accurate means of measuring ventilation in children and that it avoids the artifacts caused by using a conventional respiratory measuring apparatus.
