NASHVILLE, Tenn. -- Racial biases persist in the use of pulse oximetry devices for patients with acute hypoxemic respiratory failure (AHRF) requiring very high levels of oxygen support, a ...

血氧饱和度（SaO2）是医学中衡量血液携带氧气能力的关键指标，指血红蛋白实际结合氧量与最大结合氧量的百分比。SaO2的 ...

Serious hidden hypoxemia — defined as an SaO2 less than 88% despite an SpO2 of 92% or greater — occurred in 0.6% of the critically ill Asian patients studied. Hypoxemia went undetected in 0.8% of ...

The EquiOx study showed that in critically ill patients, oxygen saturation assessed by pulse oximetry (SpO 2) was often lower than arterial oxygen saturation (SaO 2 ...
