What Is a Pulse Oximeter and How Does It Work?

If you're looking for the best pulse oximeter, you’re not alone. With more people monitoring their health at home, pulse oximeters have become a go-to tool. But what exactly is a pulse oximeter, and how does it work?

Understanding Pulse Oximeters

A pulse oximeter is a small, lightweight device that clips onto your fingertip to measure blood oxygen saturation (SpO2) and pulse rate.

These two indicators help assess how well oxygen is circulating in your body. The Best Pulse Oximeter for Fingertip Accuracy gives accurate readings in under 10 seconds and is easy enough for anyone over 12 years old to use.

How Does a Pulse Oximeter Work?

It works using light sensors that shine through your skin. One sensor emits red light, and another emits infrared light.

The amount of light absorbed by your blood changes depending on your oxygen levels. The oximeter calculates this and displays the percentage of oxygen in your blood—typically between 95% and 100% for healthy individuals.
