The Apple Watch has become an exceptional health tool, packing numerous features to help keep an eye on everything from your heart rate to sleep.
One of the newer health features added to recent Apple Watches is the ability to measure your Blood Oxygen level and in this guide we’ll show you how to do it.
Before we start it’s worth noting this feature is only available on the Apple Watch Series 6 and Apple Watch Series 7, so if you have an older Apple Watch or an Apple Watch SE then you’re out of luck.
What you’ll need:
An Apple Watch Series 6 or Series 7 (we used the Series 7 for this guide)

The oxygenation of your blood is vitally important because it allows your cells to create energy through respiration, with it can then power all of your essential bodily functions. The NHS advises that you should ask for medical help if your SpO2 number stays at 92% or less.
