A pulse oximeter measures the amount of oxygen reaching the areas of your body furthest away from your heart. Complications from COVID-19 frequently arise when your lungs can't pump enough oxygen to the rest of your body. An oximeter helps to show when your oxygen levels may be dropping.

While only a medical professional should assess your physical condition, the readings on an oximeter can be excellent data to provide your doctor or other healthcare professional to help evaluate whether you require medical attention.

How do I read a pulse oximeter?

Typical pulse oximeters monitor two things: your pulse and your SpO%. The SpO% reading is your oxygen saturation, or the amount of oxygen carried in your bloodstream.

Most oximeters should indicate your pulse with the letters BPM, or beats per minute. A typical resting heart rate for most adults is between 60 and 100 beats per minute. The oximeter should also indicate your oxygen saturation with the letters SpO%. Your specific oximeter model may vary.

Some pulse oximeter readings require a caregiver or health professional to read them rather than the patient. The numbers may appear upside-down if you're using the oximeter on yourself. It can be easy to read the numbers backwards or mix up your pulse reading with your oxygen saturation reading.

Refer to your oximeter's instruction packet for proper use and how to read your specific model. Or, refer to the FDA's guidelines on pulse oximeters, their accuracy and limitations.

What’s a normal reading on a pulse oximeter?

Values in the normal range are typically between 95% and 100%. According to the Mayo Clinic, readings below 90% are considered low. If you’re concerned about a low blood oxygen reading, seek immediate medical attention.
