There are certain mechanisms in our body that we don’t really pay attention to. One such is the amount of oxygen in our blood. If we don’t have the right amount of oxygen saturation, it can be Bad News Bears. Thankfully, we don’t really have to worry about this too often, as it’s mainly mountain climbers and pilots who would have to worry about it. If you should fall into either of those categories though, you’ll be pleased to know that there are ways of tracking your blood oxygenation.

The iSpO2 will noninvasively track your levels, as well as your pulse rate and perfusion index. This will function while you’re working up a sweat, or even with low bloodflow in your hands. It latches on to your finger, and as you can imagine from the name, will only work with iDevices from the 3rd generation to the 4th. This is for a very specific purpose, and is rather costly at around $250 (likely because of the convenience of it giving you results on your smartphone). From using this with the corresponding app, you’ll get data history, and can be emailed your results. This isn’t intended for medical use, so it’s really more of a fancy toy, as there are cheaper versions out there that aren’t going to pair with your phone.
