My sleep doc has given me an overnight oximeter a couple times to re-gauge how my current pressure at the time is doing versus the new pressure, but I never get to see any of the readings. It would be nice to have my own that I can use frequently and play around with different pressures. I have a high quality Nonin brand pulse ox, but it’s just a standard device that isn’t designed for recording. There are some of Amazon, but they seem to have not so great reviews. So do any of you use one or have suggestions?
