iHealth Wireless Pulse Oximeter


The Wireless Pulse Oximeter is a great and reliable way to spot-check your blood oxygen saturation (SpO2) and pulse rate wherever you are.

The measurement of blood oxygen saturation (SpO2) and pulse levels is useful with chronic diseases such as asthma or COPD (Chronic Obstructive Pulmonary Disease) to quickly determine the severity of their condition.

With iHealth, you can give yourself, your family and even your doctor a more comprehensive and reliable view of your health.

Keeping track of blood oxygen saturation is also a great incentive for smokers who are trying to quit as they can see the changes in their blood oxygen saturation and thus remain motivated. As for sports, measurement of pulse and SpO2 are a great way to help users understand how their bodies react to exercise.

Very easy to use, this small and lightweight device instantly displays your measurements on the screen and on the free iHealth MyVitals application. Synchronise your results on your Apple smartphone or tablet to track the evolution of your chronic disease or simply to analyse your sports performance. The MyVitals app allows you to get an all-round picture of your health as it works with the other devices in the iHealth family such as blood pressure monitors, activity tracker and scales.

Q: How does the iHealth Wireless Pulse Oximeter work?

A: The iHealth Pulse Oximeter measures the amount of oxygen in your blood and your pulse rate.

The Oximeter works by shining two light beams into the small blood vessels or capillaries of your finger, reflecting the amount of oxygen in the blood and displaying the measurement on the oximeter’s screen.

The oxygen saturation (SPO2) is measured as a percentage of full capacity.

Q: What is the normal average pulse rate?

A: Most adults have a resting heart rate of 60-100 beats per minute (bpm). However, the fitter you are, the lower your resting heart rate is likely to be. For example, athletes may have a resting heart rate of 40-60 bpm or lower.
