False Positive on CA while Awake
#11
RE: False Positive on CA while Awake
Gideon,  

Thank you for the analysis.  If I understand flow limit correctly, it measures once ability to breath & people with asthma, COPD, allergy, stuffy nose, deviated septum all may suffer from this.  

I have a terrible time sleeping with nasal pillow if my nose is even partially stuff on even one nostril. 
My daily practice:
1. Wash my face, eyes, (nostril with saline nose spray) every time I come back home, to minimize exposure to pollens & dust.
2. Use corticoid steroid (Flonase, Nasalide) before going to bed (as needed, to avoid overuse)
3. Do not eat after early dinner. Go to bed with full stomach is bad for breathing.  
4. Eat high fiber,  low fat diet;
5. regular exercise 
6. Suffer from dry mouth, dry eyes from CPAP...drink water, use eyedrops, wash nostril with saline spray every time I wake up to go to bathroom. Often time, wake up with loud ring in eyes (24 hr tinnitus) due to cpap high pressure maybe...not much you can do.

My APAP setting currently is EPR 3;  7.8 min  11.0 max  Humidity 2   85F  (go to Hum 3 in winter)  change to single pillow (I am back sleeper)     Can't think of anything else to tweak....schedule to see new pulmonary doctor 7/13.

Welcome any suggestions!

I wouldn't worry about CA but about (presumably) heavy, non detected flow limitations from 22:30 to 23:50 and 3:40 to 5:00. They are falsely counted as respiration and reported as insanely high respiration rate.

Multicast,

about (presumably) heavy, non detected flow limitations from 22:30 to 23:50 and 3:40 to 5:00. They are falsely counted as respiration and reported as insanely high respiration rate

What do you mean by "non-detected flow limitations and falsely counted as respiration and reported as insanely high respiration rate?"

Does Resp.Rate and minute Vent. help to support what you are saying? I added Resp.rate and Minute Vent. to the attached. What is significance of these data?

RE: False Positive on CA while Awake
It's possible that the Resp Rate calculation is based on zero crossings rather that the number of peaks or valleys per minute. The only way to tell for sure is to zoom further in, from 3:41:20 to 3:42:20, and also set the Y-axis to +/- 50, and finally turn on the zero red line. These can be set by menu(left) clicking beside the left edge of the graph.

With that amount of zoom we can easily tell if you are do fast shallow breathing or simply bouncing around the zero line during your exhale phase.

As for the significance, your Minute Vent - the total volume in and out - stayed pretty much the same, so your oxygen levels probably did not change much. Slower deep breaths are more relaxing, however.

Pholynyk,    I think I did what you suggested. See attached. Your analysis?

RE: False Positive on CA while Awake
That's waht I had in mind.

In the first 8 or 10 breaths after the CA, you can see how the exhale kind of trails off and bumps over and under the zero line before you start to inhale. That's the kind of thing that confuses a zero-crossing counter. It doesn't seem to be happening here, though.

After that we get to the curious part. I judge it to be shallow rapid panting, and I have no idea why it started or how any machine settings could reduce it. Normal breathing is deeper and slower, so it may be due to excitement or anxiety. I have no idea.

And now to bed.
