WebOxygen saturation greater than 95% is considered normal. Values between 90-95% represent a slightly blunted capacity to carry oxygen, and may or may not be indicative of a meaningful deviation from normal. However, oxygen saturation below 90% (hypoxemia) is considered low and usually suggests an abnormality in oxygen handling.
