Masimo – MightySat Pulse Oximeter

Product Test With Coach Jools


Masimo – MightySat Pulse Oximeter

Masimo sent us over their MightySat Pulse Oximeter to test so we gave it to ‘Coach Jools Allen’ to check out and integrate into a number of his XLR8 training sessions with his athletes.

See how he got on…..


Just picture the scene, you’re signing riders in for a session at 8:50am on a Saturday morning and you say to a few of them at random “just slip this on your finger I want to check your oxygen levels.” Creates a bit of a buzz amongst the group I can tell ya.


So what is a Masimo MightySat Pulse Oximeter, and why on earth might you need one?

Well, in short it’s a cool little device that takes your pulse, measures the oxygen saturation of your blood and allows you to keep track of your readings through the free app. It’s super easy to use, with no set up, just open the jaws and clip it on your finger and it does the rest for you. It uses the leading hospital-grade technology (Masimo SET) for accurately measuring oxygen saturation (SpO2) and pulse rate (PR) even during movement or low blood flow and Perfusion Index (PI) on an easy to read display. You can also connect it via Bluetooth to your Android or Iphone and get the display on the screen in the Masimo Personal Health app. The app is great to track, trend and share your data.

The why you might need one bit is a little more complex to explain but in short it provides breakthrough measurements that are not available on other health or wellness devices to help you assess changes in breathing rate, breathing effort, hydration, or other factors. For “athletes” this data can help in training to track the state of your body before, during and after exercise and ensure you are getting the right amount of recovery or fluid to perform at your best.


As I said in the intro, I used it during a few coaching sessions on a variety of riders just to see what the numbers were and to see if we could find any trends. The youngest guinea pig had the highest SpO2 reading with a full 100% saturation at the start of the session where the eldest had the lowest reading at 96%. On a little more investigation the elder rider was also an ex-smoker which can cause lower readings. The Pulse rate was the most useful figure I found. Being able to track pulse rates allowed me to work with riders who were at their optimum recovery state to put in a maximum effort be it a sprint effort or gate or whatever.

Should you buy one? Well, that all depends on your interest in all of the above and how deep you want to delve into your body’s performance. The device itself is super durable (trust me, I dropped it on the start hill, seeing it bounce all the way down to the bottom without a mark on it), is lightweight design and made from high quality materials which are backed by a two-year limited warranty. The only snag I can see with it is the £279RRP price tag, but it is very nearly Christmas and this could make your trainer geek buddies really happy as a stocking filler.
