背景：急性肺损伤（ALI）和ARDS的诊断标准是通过动脉血气分析测定Pao(2)/吸入氧分数（Fio(2)） [P/F]比值来评价低氧血症的程度。我们假设脉搏血氧饱和度(Spo(2))/Fio(2) （S/F）比值可以代替P/F比值来评估ALI的氧合标准。方法：测定相应的Spo(2)值
Background: The diagnostic criteria for acute lung injury (ALI) and ARDS utilize the Pao(2)/ fraction of inspired oxygen (Fio(2)) [P/F] ratio measured by arterial blood gas analysis to assess the degree of hypoxemia. We hypothesized that the pulse oximetric saturation (Spo(2))/Fio(2) (S/F) ratio can be substituted for the P/F ratio in assessing the oxygenation criterion of ALI.Methods: Corresponding measurements of Spo(2) (values
