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 相关指南也都采用这一界值来进行相关诊断 ...

Partial pressure of oxygen (PaO2) test
A PaO2 test measures oxygen pressure in arterial blood to help guide treatment for respiratory issues. This test is part of an arterial blood gas (ABG) test, which also measures other components like ...
