Contec SpO2 meter went crazy

How do I keep this from happening? I suppose it's due to bad connection to my finger?
The alarm never went off.

Same thing happened last night, when I needed it. I woke up out of a dream or something, felt like I had low SpO2. Checked my Oximeter but it is just like the chart above, so i cant use it. My ResMed didn't report any CA or OA during this period. 

I'm not sure what other spo2 probes I could get that wouldn't have this issue and be compatible with Oscar.

What model CMS-50 do you have?

What model CMS-50 do you have?

CMS-50F.  The blue color model. This is the second one I purchased. First one the band broke on it, and finger sensor started giving issues too. Do you know if the Bluetooth black color model, (Plus) is better? It supposedly has a different finger tip reader?


My main concern is I have occasional mornings where I feel oxygen deprived and left side of my chest has unusual tiredness. I'm having an Echo Stress Cardiogram on Thursday. 

But previous Echo I had never found anything. I'm thinking it could be residual blood clots going thru my heart or some type of occassional heart block or bad circulation at night. I'm on Xarelto for blood clots, due to past DVT/PE and Bystolic beta blocker.

There's always the somewhat more expensive option of buying the oximeter kit that connects directly to the xPAP machine. The easily found online price is ~$950 but there was a thread on here saying it's much less if you call supplier # 19, see http://www.apneaboard.com/forums/Thread-...-10-SERIES

If you do that it just imports into OSCAR along with your regular data, no extra oximetry import.

(note I'm referring to the ResMed one. I know there's one for DreamStation but haven't looked into that at all)

That isn't right and may be faulty. The sensor will false read when bumped etc. Sit quietly recording while awake for an hour and see if it is the same. I have a cms50f and I don't see the large line drop more than a few time a night on oscar and is filtered in the CMS software. The unit would be under warranty if faulty.

It still does it. The last unit I bought in June 2018, so it's just over a year old and no longer in warranty. And they say the probes have only 6month warranty. So I'm out of luck. I have not even used it very much. I don't use it every night. This morning I woke up not feeling well, and wanted to check my O2, and the graph was totally messed up again. I have been video recorded myself at night, and don't move my hand, so this isn't caused by movement. I had the alarm set to 90%, and it never went off, so I'm pretty sure those readings are totally false. There is no way my oxygen drops to 60% sharply like that multiple times in a row. That is totally incorrect.
