SpO2 and PaO2 are both indicators of oxygenation, aren't they? The barrier to entry is likely lower for SpO2, isn't it?

Introduction Targeted oxygenation protocols in mechanically ventilated patients are critical in avoiding the deleterious effects ...

To evaluate partial pressure of oxygen in arterial blood/fractional percentage of inspired oxygen (PaO2 /FiO2 ) and SaO2 /FiO2 ...

Problem While SpO2 is a good approximation of SaO2 when saturation is above 90%, this is not necessarily the case at lower saturations (see for example Lebecque, 1991). It is also treated separately ...

Chronic obstructive pulmonary disease (COPD) is globally the third leading cause of death, causing 3.23 million deaths in 2019.

"The patient is lethargic, but their SpO2 is 98%, so their breathing is fine." Anyone who nods at this statement will definitely ...
