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 ...

本研究通过回顾性多中心分析发现，衰弱患者急性呼吸窘迫综合征（AHRF）高发，且AHRF严重程度与衰弱程度均显著增加住院死亡率，呈现非线性关联。 尽管针对急性低氧血症性呼吸衰竭（AHRF）的重症患者的研究正在增加，但这种状况与患者虚弱状态之间的相互 ...

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 ...

In a recent study investigating the effects of prostaglandin E1 (PGE1) on reducing inspired oxygen concentration during one-lung ventilation (OLV), several key findings and outcomes were identified.

为解决评估急性呼吸窘迫综合征（ARDS）严重程度时，仅依靠 Pa O 2 /FiO 2 存在局限性的问题，研究人员开展了 ARDS 分类的相关研究。结果表明仅用 Pa O 2 /FiO 2 分类存在不足，为未来研究指明方向，有重要意义。 在医疗领域，急性呼吸窘迫综合征（ARDS）一直是重症 ...

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 following is a summary of “Prognostic value of PaO2/FiO2 ratio in predicting clinical outcomes in COVID-19 patients,” published in the June 2024 issue of Critical Care by Canto-Costal et al.

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)。

The PF ratio (PaO2/FiO2 ratio) is an essential indicator used in medicine to gauge the severity of a patient’s hypoxemic respiratory failure. This value helps healthcare professionals determine ...

Calculating the partial pressure of oxygen in arterial blood (PaO2) is an essential skill for medical professionals, especially in assessing a patient’s respiratory health. This article will provide a ...
