PaO2/FiO2 的参考范围为 350 ~ 500 mmHg（年龄越大，参考值越低）。 Horovitz 等人认为 PaO2/FiO2 ≤ 300 mmHg 意味着存在显著的肺部功能障碍（诊断 I 型呼吸衰竭要求海平面大气压下 PaO2 ＜ 60 mmHg，空气 FiO2 为 21%， PaO2/FiO2 大致计算为 ＜ 300 mmHg），后续柏林定义及 ARDS ...

PaO2/FiO2（PF）比值被广泛用于评估重症患者的呼吸衰竭情况，以指导通气策略和预后判断。然而，由于该指标需要侵入性动脉 ...

本研究针对Erlebach等人发现的SpO2/FiO2(SF)与PaO2/FiO2(PF)比值在ARDS分型中存在显著不一致性问题，通过MIMIC-IV数据库对582例机械通气 ...

当我们谈及呼吸衰竭，其实更关注的是呼吸衰竭的病理生理机制以及基于此机制最终产生的结果。无论是通气功能障碍，还是换气功能障碍，都会导致氧气无法正常在体内运输，进而出现缺氧状态。通过氧输送（DO 2 ）公式【DO 2 =CaO 2 ×CO×10，CaO 2 =Hb×1.34×SaO 2 +PaO ...

A PaO2 test measures partial pressure of oxygen, or PaO2—the oxygen pressure in arterial blood. The PaO2 reflects how well oxygen is able to move from the lungs to the blood. It is often altered by ...
