After some trouble with the pulse oximeter machine that was dropped off at my house, the company took it back and deemed that they didn’t like the results they saw, so they asked me to do the test again, which I did. It measures your heartrate as well as the oxygen levels in your blood. I was able to get a decent amount of sleep and everything appears to have functioned well.
I’m glad to have that done and out of the way. Hopefully have the results next week at some point.
