目的 Qt和PaO2/FiO2,对结果进行回归分析.结果 ①Qsp/Qt和PaO2/FiO2两者之间存在线性相关,但决定系数r2只有0.432,相关性偏小；②Qsp/Qt(％)的多元回归方程:y=56.542-3.371x1-0.056x2+0.594x3+2.84x4,x1为PaO2/FiO2,x2为Hgb,x,为PAWP,x4为CI,校正r2 =0.538,(P＜0.01).结论用PaO2/FiO2测算ARDS的Qsp/Qt精确度下降,决定系数r2只有0.432,Qsp/Qt除外PaO2/FiO2还受Hgb、肺动脉楔压(plumonary artery wedge pressure,PAWP)及心脏指数(cardiac index,CI)等影响.
