What are good Oxygen levels for the blood

The amount of oxygen in the blood is indicated as a percentage, also called (oxygen) saturation. Saturation indicates a value that indicates with what percentage (SpO2) the hemoglobin in the red blood cells has bound the oxygen.
For a healthy person, a saturation value of 95% or higher is considered normal. At a value of 90% or lower, there is a shortage, also called desaturation.

How to Measure oxygen in your blood

Use a Pulse Oximeter to measure your Blood Oxygen levels

A simpler way to measure the oxygen level in the blood is with the help of a blood oxygen saturation meter, also called a pulse oximeter. By placing it on the index finger, a result can be read within seconds. However, this measurement is less accurate, because measurements may deviate due to movement, cold fingers, anemia, nail polish / artificial nails, and an irregular heart rhythm.

Which arteries contain oxygenated blood?
