PaO2 需要有创动脉穿刺操作才能获取，而脉搏血氧饱和度 (pulse oxygen saturation, SpO2) 是一种无创测量法。 其原理是测定毛细血管床氧合血红蛋白百分比，SpO2 并不测量被其他分子饱和的血红蛋白，如碳氧血红蛋白或高铁血红蛋白。

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 ...

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 ...

氧和人的生命息息相关。人体内储存的氧极少，正常健康成人氧储备约为1500毫升。在静息状态下，人体每分钟氧耗量约为250毫升，缺氧5分钟即可对大脑造成不可逆性损伤。因此，及时准确地判断人体是否缺氧是十分必要和紧要的。 通常我们可以通过观察指甲甲 ...

When a patient is receiving supplemental oxygen during surgery, there’s a risk that they’ll develop hyperoxia, where their arterial blood becomes oxygenated above normal levels, potentially leading to ...
