   Jan 13, 2023 · Pulse oximeters are most accurate when blood oxygen saturation is between 90% and 100%. Accuracy decreases when blood oxygen saturation is between 80% and 90%, and the devices are least accurate when saturation is below 80%. Keep in mind that readings may be off by a few percentage points.

   What if a pulse oximeter reads 90%?

   • Keep in mind that readings may be off by a few percentage points. For example, if an FDA-cleared pulse oximeter reads 90%, then the actual oxygen saturation in the blood is generally between 86% and 94%. Most healthy people have blood oxygen levels between 95% and 100%, but this can be lower for people with lung problems.

   What is a pulse oximeter?

   • Pulse oximetry is a quick and noninvasive test that measures the oxygen saturation level in your blood using a device called a pulse oximeter. It helps monitor how well oxygen is being delivered in the body. Low oxygen levels can occur due to health conditions such as asthma, pneumonia, or chronic obstructive pulmonary disease (COPD).
