Have you ever had an experience like this in the ICU or an acute care ward? When SpO2 dropped, the only thing you could think of was 'let's take a break for now.' Even when shown blood gas values, you ...

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 ...

Abstract: This paper proposes a novel mathematical model that quantitatively defines the relationships between the arterial oxygen saturation (SaO2), the arterial partial pressure of oxygen (PaO2) and ...

（长按 识别二维码 搜索更多麻醉学知识点） 氧合血红蛋白并不能直接被机体所利用，需要氧分子从血红蛋白上解离出来，才能够进入机体的组织细胞。我们在临床上也利用了血红蛋白的物理化学特性。氧离曲线从起始段到快速升支直至平台段这一过程是由血红 ...

Near-infrared spectroscopy (NIRS) measurement of regional cerebral tissue oxygen saturation (rcStO2) has become a topic of high interest in neonatology. Multiple studies have demonstrated that rcStO2 ...

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 ...
