Objectives COVID-19 causes lung parenchymal and endothelial damage that lead to hypoxic acute respiratory failure (hARF). The influence of hARF severity on patients’ outcomes is still poorly ...

The following is a summary of “Clinical Performance of Spo 2 /Fio 2 and Pao 2 /Fio 2 Ratio in Mechanically Ventilated Acute Respiratory Distress Syndrome Patients: A Retrospective Study,” published in ...

The pulse-oximetric peripheral oxygen saturation to a fraction of inspired oxygen (SpO 2 /FiO 2) ratio has been suggested as an additional hypoxemia criterion in the new global acute respiratory ...

呼吸衰竭的主要判断指标包括血氧分压PaO2、二氧化碳分压PaCO2和氧饱和度SpO2。当PaO2低于60mmHg，PaCO2高于50mmHg，或SpO2低于90%时，可能提示呼吸衰竭。呼吸衰竭分为I型和II型，I型以低氧血症为主，II型则伴有高碳酸血症。 1、血氧分压PaO2 PaO2是血液中氧气的压力 ...

Abstract: To effectively monitor the status of critically ill patients, particularly in clinical scenarios such as the prevention of pressure injury (PI), it is crucial to accurately measure blood ...

Using a BVM (with or without O2) on an unconscious and breathing patient with stable airways, does not affect SpO2 recovery in any way. Unless I'm mistaken, supplemental O2 should definitely shorten ...

Discrepancies between pulse oximetry and arterial oxygen saturation can pose challenges in clinical assessment. Possible underlying causes include poor peripheral perfusion, skin pigmentation, motion ...

（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 ...

Abstract: Although many pulse oximeters are available in market with different blood oxygen saturation (SpO2) equations presented in the past studies, we investigate the performance of ten existing ...

血气中哪些常用测量指标代表氧和状态？ 氧合作用受损时，可能无法满足外周组织的代谢需求。有多种方法衡量氧合是否受损。 常用指标包括动脉血氧饱和度(SaO2)和外周血氧饱和度(SpO2)、PaO2、肺泡-动脉(A-a)氧梯度，以及动脉血氧分压与吸入氧分数比值(PaO2:FiO2)。
