Finger Tip Pulse Oximeter

What is Pulse Oximetry?

For people with COPD, asthma, Congestive Heart Failure (CHF) and other conditions, pulse oximetry is a technology used to measure the oxygen level in your blood and your heart rate. A finger pulse oximeter is equipped with technology to rapidly detect changes in your blood oxygen level. It can help give you the knowledge you need to take control of your condition. A finger pulse oximeter is easy to use – just clip it on your fingertip to get a blood oxygen reading.

How Does a Pulse Oximeter Work?

A finger pulse oximeter functions by shining light through your finger. The sensors detect how much oxygen is in your blood based on the way the light passes through your finger. Pulse oximetry is the technology calculating the results to display a number on the oximeter’s screen that tells you the percent of oxygen in your blood. A finger pulse oximeter also measures your pulse rate.
