CPAP Vets, Please Glance at my First Week...

[Pugsy]

That 3 AM ugly cluster is probably awake falsely reported events due to the mask discomfort. It sort of skews your nightly numbers. If you think that is the time you woke up..for sure awake or semi awake events being falsely flagged and thus overall AHI number is not reliable.

AHI can be worse when we have leaks under control because the machine can't score properly during a large leak so that means during large leak times you very well could have several apnea events and the machine simply couldn't sense them because of the large leak. So even without that ugly 3 AM cluster it is possibly that with the leaks under control to be elevated because the machine is now able to sense them and identify them.

Your machine wants to stay around 10 cm most of the night. If this continues...a little increase in that minimum should bring that AHI down a little more and probably give you a consistent low AHI.
We can't really judge overall AHI from this report because it includes that cluster which messes with the numbers.

The machine doesn't know if you are awake or not and sometimes it is fooled by your breathing pattern while awake.

OK, now that you show some higher AHI you are starting to look like me. At least we know now that we have pure Sleep Apnea and no Central Apneas Syndromes and we have no UAR syndrome (as I mentioned before that you might have), and als no insomnia (this is b/c we can continue to fall a sleep, after we wake up, within a few minutes) . Those leak spikes that you have, come when you shut the machine only after you play with the mask. I get such spikes when I sneeze into the mask after lifting it a bit. If I don't lift and sneeze then the non- re breathing valve pops up and become non functional (this valve is located in the elbow above the step down plastic pipe that you were be looking for). But I often have even much worse leaks than you show when I use my less efficient masks. I like to use three diff masks in sequence so as not to get stripes on my face. See my graph and Stat from yesterday:

Note that I have higher nocturia than you by waking up more times. The gap in the pressure graph show their numbers.
I bet that my higher Flow Limitation is also b/c of having some UAR incuded in it.



the following is my statistics:
