Pulse oximeters are devices used to monitor someone’s oxygen levels. By clipping it onto your finger, you can get results in just a few seconds. The device will display your oxygen levels (SpO2), as well as your heart rate (HR).
The pulse oximeter only gives an approximate measure, so you should track your results overtime for a better understanding of your condition. Knowing how to use it correctly can also lead to more accurate results.
