newly oxygenated red blood cells carry oxygen to your body a pulse oximeter uses light to measure the oxygen saturation level the percentage of hemoglobin in your red blood cells carrying oxygen normal oxygen saturation levels fall between 95 and 99 percentrterial blood oxygen while a pulse oximeter is the most common device used to determine your blood oxygen level it is sometimes necessary to analyze blood taken directly from an artery to assess your oxygen level this measurement is called an arterial blood oxygen
