Research Notes on Oxygen Saturation Test


An oxygen saturation test is a medical test that measures the amount of oxygen being carried by red blood cells. One method uses a device that shines light through a finger.

Fast Facts:

  • Some patients say blood drawn from an artery hurts a little more than when drawn from a vein.1
  • The results of a blood draw are available in about 15 minutes at most laboratories.2
  • Measuring with the fingerclip gives the oxygen level and the pulse rate immediately.2
