I would second PaulaO2's recommendation for a wrist unit. The finger clip units are hard to secure, and movement will lead to bad data. Another quirk of the CMS50D+ is that it will only save a single session, and its time always starts at 0:00:00.
I also second the other recommendation. You don't really want to wake up when your O2 goes low; you want to prevent the O2 from going low. You, and the people around you, /can/ adapt to the mask and hose and machine, and you will sleep much better, and feel better all day too.
WELCOME! to the forum.!
The CPAP machine and mask treats your sleep apnea, an oxemeter won't treat it.
Much success to you on your journey, hang in there for more responses to your post.
I recommend the CMS 50F, in particular the model with the Innovo silicone probe, which is MUCH more comfortable to wear during sleep than most probes. This model a significant step up from the 50D+ and is fairly easy to sync up with CPAP data.
Thanks so much for the responses I really appreciate it and I'm not just saying it this means a lot to know that people care I wish all of you the best!!!!and good fortune too!!!
Good morning! I looked for an alarming & recording oximeter for exactly the same reason - really didn't like knowing I was sleeping through dangerous oxytem levels. So, below I am giving a cut and paste now of a post I wrote to someone else on the topic of oximeters. Though am new to this whole thing, sure want to also, first, repeat the advice of those more experienced to not rely solely on the alarm as the permanent fix. That being said, here's info on the alarming monitor I use ...
I have had great experience w/CMS 50F, recording oximeter worn like a wristwatch. Have taken it to appt at doctor's offices to test against "real" oximeters and it tracks perfectly. Data displays on the watch face and it connects w/reasonable length of wire to a very lightweight sensor that clamps on a finger and stays secure. Though watch is a little cluncky in size, it is lightweight and stays put very well. Batteries are rechargeable, but it doesn't seem to need a recharge too often - takes about 5 or 6 days before the battery indicator starts showing the charge is reducing. Seems to take a few hours to charge up to a full load at that point. Manual isn't great but I could figure things out pretty quickly in spite of being a Tyrannosaurus Tech, a term we elders coined for ourselves in response to being termed "dinosaurs" by a wiseguy hipster who worked in the I.T. dept. where I worked before I retired 2012. Reportedly the device will give you its data in wonderful ways via bluetooth, but I don't understand bluetooth w/Windows 10, so I, instead, print copies of the oximetry reports the monitor software generates, and print 1 or 2 as pdfs to bring along to appointments to show typical nights to the doctor. One caution - the "watch" doesn't respond well to being accidently dropped onto hard surfaces, but worked like a champ for months before that calamity. Was impressed enough overall to buy the same model as a replacement, and expect the new one I bought to arrive today.
