A: Blood oxygen level is measured using pulse oximetry, a noninvasive procedure designed to monitor the delivery of oxygen to peripheral tissue, says Johns Hopkins Medicine. Pulse oximetry uses hemoglobin coloration and blood flow pulsation to measure the blood oxygen level.
The oxygen saturation of arterial blood is normally 95-98%, whereas the saturation of venous blood is typically 60-80%. The saturation in venous blood is referred to as mixed. venous oxygen saturation (SvO. 2). It reflects the average. saturation of venous blood as it returns to the right side of. the heart from the various tissues. Generally, the tissues of a. resting individual use approximately 25% of the available.
