Home PulseOx Recommendation

I'd like to monitor my oxygen saturation each night. Can anyone recommend a product they've purchased and are happy with?

If you go to amazon and search for a pulse oxymeter, you will see most are Chinese made and fall into a couple distinct categories. You can get them that fit to your finger and measure real time pulse and SPO2 level. This won't help you much since you want something for when asleep. There are those that fit onto your finger and have a cord going to a device that records. This will work but you will need to make sure the device doesn't become unplugged if you move your arms. The last type is the type that looks like a wrist watch. This is the recording part. There is a rubber monitor that fits on your finger and a short cord attaches to the wrist watch recording part via USB. You set it to record and it has plenty of power to record over night and then dump the results via the same USB cord to a computer where you have downloaded the manufacturer's software. You will then be able to play back the pulse and SPO2 info in various graphic display modes but can easily see O2 drops and highs and averages, etc.

This is the one I use or looks just like it. It seems accurate. The software instructions were written by a non-English speaker and are not real clear but you can figure things out: https://www.amazon.com/Wrist-worn-Pulse-Oximeter-Software-Download/dp/B00LN4LCMC/ref=sr_1_2_a_it?ie=UTF8&qid=1498045896&sr=8-2&keywords=recording+pulse+oximeter
