Pulse oximetry is one of the most widely used medical technologies worldwide, yet it performs less accurately for people with darker skin.1 This inequity requires urgent action. In a linked study, ...

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 ...

本文系统阐述了低氧血症（Hypoxemia）的评估方法（脉搏血氧饱和度SpO2和动脉血气分析PaO2）、诊断标准（PaO280 mm Hg或SpO295%）及其三大成因（低吸入氧浓度FiO2、低通气与静脉血掺杂），为兽医临床提供了一套从监测到氧疗的完整管理方案。

At 1 year after participants’ ICU stay for acute respiratory failure, mean DLCO was about 5% lower in those who had an ICU oxygenation target of 60 vs 90 mm Hg. Cognitive impairment levels among ...

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 ...

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 ...

（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 ...
