- Normal Ranges. Oxygen saturation level in healthy patients is considered normal between 97 percent and 99 percent. Patients who have normal hemoglobin levels can have a saturation level of 95. When the amount of oxygen in the blood is reduced, a condition known as hypoxemia results, and treatment is then required.

When the amount of oxygen in the blood is reduced, a condition known as hypoxemia results, and treatment is then required.xygen saturation refers to the level of oxygen carried by red blood cells through the arteries and delivered to internal organs. As red blood cells travel through the lungs, they are saturated with oxygen. A low saturation level could indicate a respiratory illness or other medical condition.

Hypoxemia Hypoxemia (or hypoxaemia in British English) is an abnormally low level of oxygen in the blood.[1][2] More specifically, it is oxygen deficiency in arterial blood.[3] Hypoxemia has many causes, often respiratory disorders, and can cause tissue hypoxia as the blood is not supplying enough oxygen to the body.

- Oxygen saturation is a term referring to the fraction of oxygen-saturated hemoglobin relative to total hemoglobin (unsaturated + saturated) in the blood. The human body requires and regulates a very precise and specific balance of oxygen in the blood. Normal blood oxygen levels in humans are considered 95-100 percent.n SaO 2 (arterial oxygen saturation) value below 90% causes hypoxemia (which can also be caused by anemia). Hypoxemia due to low SaO is indicated by cyanosis. Oxygen saturation can be measured in different tissues: 1  Venous oxygen saturation (SvO 2) is measured to see how much oxygen the body consumes.

Definition By Mayo Clinic Staff. Hypoxemia is a below-normal level of oxygen in your blood, specifically in the arteries. Hypoxemia is a sign of a problem related to breathing or circulation, and may result in various symptoms, such as shortness of breath. Hypoxemia is determined by measuring the oxygen level in a blood sample taken from an artery (arterial blood gas). It can also be estimated by measuring the oxygen saturation of your blood using a pulse oximeter — a small device that clips to your finger. Normal arterial oxygen is approximately 75 to 100 millimeters of mercury (mm Hg). Values under 60 mm Hg usually indicate the need for supplemental oxygen.

Medical Dictionary Hypoxemia: abnormally low levels of oxygen in the blood. Hypoxemia may be mild to severe and leads to shortness of breath. Low blood oxygen can result from a variety of conditions that affect either the ability of the heart to pump blood to the lungs to receive oxygen or the function of the lungs themselves.

My oxygen level is 91% Is that too low? Answer Wiki. Medical professionals generally consider an O2 sat of 91% too low - but keep in mind that various factors can affect oxygen saturation and a person's normal level. COPD patients frequently have O2 sats around 93-94% that we do not treat because their bodies have become accustomed to that level and raising it too much can be detrimental for them.
