Fingertip Pulse Oximeter (most likely Banggood or AliExpress)

Here’s something you might find useful if you are interested in your pulse and blood oxygen levels (and don’t have a suitably equipped smart bracelet). For under £12 sterling, this handy device (Gearbest link removed as they are now defunct – Sept 2021) might just do the trick.

Fingertip Pulse Oximeter

Fingertip Pulse/OximeterSimply pop in a finger and press the button. The gadget works in all 4 orientations and gives clear, bright readings, uses 2 AAA batteries and claims 2-3% accuracy, more I think than some smart bracelets.

How about continuous reading and a handy bar graph in the middle.

The unit works over a wider range of temperature than I do. And no, it doesn’t poke any holes in you. I had no idea my blood oxygen levels varied so much. I just happened to pop into the house do demo to my wife and as it happened a nurse friend of ours was over and explained the effect that deep breathing has on this. Now I can actually take live measurements it is a lot less abstract than before today.  Good gadget.

  1. I bought one of these a while back. It works as expected except that it drains the batteries even if it isn’t in use. I’d put new batteries in it and put it in the desk drawer, come back a month or so later and the batteries were dead.

    1. Well, days later I’m having no battery problems. Of course I only use l alkalines (or rechargeables as appropriate)
