Whatever device you use, it's a really good idea to get an oxymeter
to be able to measure your blood oxygen. I picked one up on eBay
for about $35 (new).

I second the motion. Amazon also has them, starting at $23. Or get one
with alarms ($70 or so), or alarms and logging ($130), for very
reasonable prices.

Has anyone tried the alarm and logging units?
