Poor oxygenation can be detected by low pao2
WebA high mortality of 45.4% was found in the Sirohoya study in India. 14 Similarly, a study in the UK reported room air oxygen saturation as a significant predictor of patient outcome and mortality. 32 This is also confirmed by a Peruvian study reporting that oxygen saturation below 90% on admission was a significant predictor of in-hospital mortality in patients … WebDec 21, 2024 · 75-100 mmHg: Normal arterial oxygen pressure (PaO2) is approximately 75 to 100 millimeters of mercury (75-100 mmHg). Below 75 mmHg: When the levels drop below 75 mmHg, the condition is called hypoxemia. Below 60 mmHg: Levels below 60 mmHg are considered very low and indicate the need for supplemental oxygen.
