Contec CMS-50d-BT pulse Ox compatible with Oscar - Finally!!

Post by kwikwater » Fri Jul 25, 2025 6:15 pm

I've recently been diagnosed with atrial fibrillation and am quite concerned with my blood oxygen. I've had a Contec CMS50D+ pulse ox, but it had corroded batteries and is gone! I thought I found another one, on ebay, but it came as a CMS50D-BT, that Oscar can't find or read the data for. For that matter when you go to File Explorer, the data file isn't visible regardless of your settings. I finally got around that!!!

When you're looking at the pulse-ox results in SpO2 Assistant, use their File-Save As and put it where YOU know where to find it and I rename mine. I have a directory in My Documents labeled OSCAR data. **You can't copy/paste or attach it to email from SpO2 at all! There is some file managing you have to do, in SpO2 so remember where the original file is stored by Contec. For me, it's in C:Program Files (x86)/SpO2 Assistant v3 1.0.4/Data/(long file name that is the date & time)

Now when using the Oximetry Wizard in Oscar, it moves right over. You still probably need to adjust the start time to match you CPAP data and Viola - You've got your oximetry data right where you need it!

Now, I'm looking forward to a new sleep study, Aug. 7 for Bi-Pap titration and possible oxygen, but now I can keep track!!!
