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 ...

监护仪上的血氧饱和度（SpO2），即脉搏血氧仪测量的外周动脉血氧饱和度，是危重病人最常用的监测指标之一，它可以反映组织氧合状态，是持续无创评估氧合状态的标准做法，常被视为「第五生命体征」。但是临床上是否经常遇到如下问题？1. 血氧 100%，但患者自觉呼吸困难，是患者紧张还是真有问题?2. 血氧 ...

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 Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output 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 ...

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 ...

Using Sparkfun MAX3010X library https://github.com/sparkfun/SparkFun_MAX3010x_Sensor_Library SpO2 is calulated from square root means of all raw data at 50Hz sampling ...

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 ...
