Maintaining the precise balance of blood oxygen level is important to your health.
People with chronic health conditions many need to monitor their blood oxygen level.
An arterial blood gas (ABG) test is a blood test. It measures your blood’s oxygen level. It also can detect the level of other gases in your blood, as well as the pH (acid/base level).
However, a normal ABG oxygen level for healthy lungs falls between 80 and 100 millimeters of mercury (mm Hg).
Oxygen level in blood below normal known as hypoxemia. The lower the oxygen level, the more severe the hypoxemia can lead to complications in body tissue and organs.
Moreover, conditions that can negatively impact your blood oxygen level include COPD, acute respiratory distress syndrome, asthma, collapsed lung, anemia, congenital heart defects, heart disease, and pulmonary embolism.
