One addition to why I mentioned issues with sleep studies and almost all lack of CO2 monitoring.

You had a test. The doctor was there. He did NOT check you into the hospital. Please think about that. You are probably OK. If you are having trouble breathing, go to the ER. Otherwise, relax. I had a test two years ago. I've been using CPAP since then. I am attempting to do more than google by ask...

Hi, I don't have any of the common causes of Hypercapnia. My reason for asking this forum was due to a past daytime exertion test which was initially abnormal as well as symptoms and things this causes that might fit me.

In all cases for the first 5 min or so, my "respiratory quotient" was sky high. Doct...

I'm 37, never smoked, and have no diagnosis of COPD, etc. I use the SleepyHead app to read my data card as I like to try and understand my daytime fatigue...

Hi, Is there any way to differentiate low blood oxygen from high blood CO2 based on symptoms or any "at home" measurement devices? Using CPAP now at low setting for mixed sleep apnea. I also use a finger pulse oximeter that records on occasion at night. Noticed I've been fighting machine more and wh...

Hello, I was recently diagnosed with Obstructive Sleep Apnea via a split night sleep study, and have been using a CPAP device with memory card logging for about three weeks. Curious to know how my nightly sleep was going, I downloaded a software application to view my results on a weekly basis vice ...
