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). Pulse oximeters are frequently used in hospitals and clinics but can also be used at home.

Normal Ranges

Most people have a normal resting pulse oximetry reading for oxygen saturation (SpO2) between 95% and 100%. This shows that your blood has an appropriate amount of oxygen. People at higher altitudes may have slightly lower readings.

If your oxygen saturation level drops below 95%, it may suggest a potential issue with your lung or heart function. Levels below 92% are considered low and may require medical attention. You should seek immediate medical attention for a reading of 88% o
