Interesting little device. My SpO2% is 99 which is good. Pulse rate is a little on the high side but I measured it when I’d just gotten in the door from having walked about a mile.
Pulse rate is a tad high. But if I meditate on it I can bring it down below 70BPM. Interesting how that works.
And the operation of the device – it just shines a light through your finger and has a detector on the other side. That and a little bit of calculation via software derives your SpO2.
The device is really small – about the size of a hospital finger probe. And the OLED screen is gorgeous.
It’s sort of fun to be able to gauge your own body parameters.
