These guidelines will help you understand what your result might mean: Normal: A normal ABG oxygen level for healthy lungs falls between 80 and 100 millimeters of mercury (mm Hg). A healthy oxygen saturation is typically above 90%. This is an invasive blood draw. Once fully acclimatized, your peak oxygen uptake will be the same as at sea level, but the saturation of arterial oxygen will be increased i.e. For someone who’s healthy, the normal blood oxygen saturation level will be around 95–100%.

The blood will be put in an ABG machine (blood gas analyzer) that provides your blood oxygen levels in the form of the partial pressure of oxygen (PaO2). measured. However, in COPD or other lung diseases, these ranges may not apply. Hypoxemia is a low level of oxygen in the blood that disrupts body function and harms vital tissues.

Altitude Oxygen Chart displaying the levels of o2 at high altitudes. Normal Levels. Blood oxygen level is an important medical tool used to determine how effectively you are taking oxygen into your body. This can lead to complications in body tissue and organs. Many patients with lung disease will have an oximetry reading of 90%, but that is fine. Blood oxygen levels below 90% are considered low (hypoxemia).
