'''Oxygen saturation''' describes how much of the hemoglobin – the oxygen-transport protein in red blood cells (erythrocytes) – is currently saturated with oxygen. It is typically given as a percentage relative to the total hemoglobin. Expected ''normal'' blood oxygen saturation values are between 95% - 100 % and values <90% are considered to be hypoxemia <ref>https://en.wikipedia.org/wiki/Oxygen_saturation_(medicine)</ref>. | '''Oxygen saturation''' describes how much of the hemoglobin – the oxygen-transport protein in red blood cells (erythrocytes) – is currently saturated with oxygen.
