Web26 May 2024 · Oxygen levels are measured according to the percentage of oxygen saturated in your blood. This is called your SpO2 level. Normal Blood Oxygen Levels For medical purposes, a normal blood oxygen saturation rate is often considered between 95% and 100%. However, you may not experience any symptoms if your percentage is lower. Web22 Sep 2024 · The Oxygen-Hemoglobin Dissociation Curve shows the percent of oxygen binding to Hgb per mmHg. An O2 sat of 90% corresponds to a PaO2 of 60 mmHg. Note how quickly Hgb loses oxygen below 90% saturation. As the partial pressure of oxygen rises, there are more and more oxygen molecules available to bind with Hgb. life and death in one word
