Oxygen saturation (medicine) Oxygen saturation is the fraction of oxygen -saturated haemoglobin relative to total haemoglobin (unsaturated + saturated) in the blood. The human body requires and regulates a very precise and specific balance of oxygen in the blood. Normal arterial blood oxygen saturation levels in humans are 96–100 percent. [1]
The arteriovenous oxygen difference, or a-vO2 diff, is the difference in the oxygen content of the blood between the arterial blood and the venous blood. It is an indication of how much oxygen is removed from the blood in capillaries as the blood circulates in the body. The a-vO 2 diff and cardiac output are the main factors that allow ...
In its simplest form, the oxyhemoglobin dissociation curve describes the relation between the partial pressure of oxygen (x axis) and the oxygen saturation (y axis). Hemoglobin's affinity for oxygen increases as successive molecules of oxygen bind. More molecules bind as the oxygen partial pressure increases until the maximum amount that can be ...
Normal Ranges. Most people have a normal resting pulse oximetry reading for oxygen saturation (SpO2) between 95% and 100%. This shows that your blood has an appropriate amount of oxygen. People at ...
24336-0. An arterial blood gas (ABG) test, or arterial blood gas analysis (ABGA) measures the amounts of arterial gases, such as oxygen and carbon dioxide. An ABG test requires that a small volume of blood be drawn from the radial artery with a syringe and a thin needle, [1] but sometimes the femoral artery in the groin or another site is used.
What is a good oxygen level? “Normal people who have working lungs, and all those steps are going well, their blood oxygen level will usually be 96-100 percent,” adds Dr. Uppal. A few notches ...
A pulse oximeter probe applied to a person's finger. A pulse oximeter is a medical device that indirectly monitors the oxygen saturation of a patient's blood (as opposed to measuring oxygen saturation directly through a blood sample) and changes in blood volume in the skin, producing a photoplethysmogram that may be further processed into other measurements.

In medicine, oxygen saturation refers to oxygenation, or when oxygen molecules (O. 2) enter the tissues of the body. In this case blood is oxygenated in the lungs, where oxygen molecules travel from the air into the blood. Oxygen saturation ( (O. 2) sats) measures the percentage of hemoglobin binding sites in the bloodstream occupied by oxygen.
