If your finger pulse oximeter reading is below 90 percent, try testing again - in case there was a testing error - or consider contacting your doctor. Readings should typically fall between 95 and 100 percent, with readings at 92 percent or below potentially indicating that there isn’t enough oxygen in your blood. This type of reading is called oxygen saturation, or SpO2, and the results display as a percentage. The light shines through the tissues of your fingertip, and the sensor on the other side picks up the light that comes through.įinger pulse oximeters can then measure how much light comes through your finger to estimate how many of your red blood cells are carrying oxygen. These devices have light-emitting diodes, or LEDs, on the inside of the probe that can send small beams of light through your finger to track the amount of oxygen in your blood. Pulse oximeters are most commonly worn on your finger and are completely painless to use. So, to help make your search a little easier, we’ve compiled our top picks of the eight best finger pulse oximeters so you can start tracking your levels quickly and easily from home.
