A pulse oximeter is one of those small but powerful devices that can give you instant insight into your health — specifically, your oxygen saturation (SpO2) and heart rate (BPM). It's painless, non-invasive, and incredibly easy to use once you know the basics.
Whether you’re monitoring a chronic condition like asthma or COPD, recovering from an illness, or simply keeping tabs on your well-being, this guide will show you how to use a pulse oximeter the right way.
What is a Pulse Oximeter?
A pulse oximeter measures the percentage of oxygen in your blood (SpO2) and your pulse rate. It does this by shining red and infrared light through a thin part of your body — usually a fingertip — and analyzing how much light is absorbed by oxygenated vs deoxygenated blood.
