Prediction of FRC using a respiratory P-V curve (2 1 syringe method) has been tested in eight patients with normal lungs and in 12 ARDS patients. FRC was measured using nitrogen dilution technique with a closed circuit. Correlation between measured and predicted FRC was excellent, especially when the expiratory limb of the P-V curve was used (r = 0.92, in patients with pulmonary edema, and r = 0,97 when patients were evaluated after a few weeks). PEEP induced increase in FRC was larger between 10 and 20 cmH2O than between 0 and 10 cmH2O. As expected, Qs/Qt decrease was correlated with the FRC augmentation.
使用呼吸压力-容积曲线（2毫升注射器法）预测功能残气量（FRC），已在8名肺功能正常的患者和12名急性呼吸窘迫综合征（ARDS）患者中进行了测试。FRC采用氮稀释技术通过闭路系统进行测量。实测FRC与预测FRC之间的相关性极佳，尤其是使用压力-容积曲线的呼气支时（肺水肿患者中r = 0.92，数周后评估患者时r = 0.97）。呼气末正压（PEEP）在10至20厘米水柱之间引起的FRC增加大于在0至10厘米水柱之间。正如预期的那样，分流率（Qs/Qt）的降低与FRC的增加相关。
