   What is a normal blood oxygen level?

   • Blood oxygen levels (arterial oxygen) indicate the oxygen levels present in the blood that flows through the arteries of the body. Normal arterial oxygen pressure (PaO2) measured using the arterial blood gas (ABG) test is approximately 75 to 100 millimeters of mercury. Understand levels, chart, and hypoxemia.

   • Oxygen content (O2CT). This measures the amount of oxygen in the blood.
   • Oxygen saturation (O2Sat). This measures the amount of hemoglobin in your blood. Hemoglobin is a protein in your red blood cells that carries oxygen from your lungs to the rest of your body.
   • Partial pressure of oxygen (PaO2). This measures the pressure of oxygen dissolved in the blood. It helps show how well oxygen moves from your lungs to your bloodstream.
   • Partial pressure of carbon dioxide (PaCO2). This measures the amount of carbon dioxide in the blood.
