A pulse oximeter and blood oxygen saturation monitor is a non-invasive device that measures the oxygen saturation level (SpO2) in your blood and your pulse rate.

Venous oxygen saturation (SvO 2) is the percentage of oxygenated hemoglobin returning to the right side of the heart. It can be measured to see if oxygen delivery meets the tissues' demands.
