Dude

ok, so I guess the OP needs to figure out where he stands than.

it's nuerological if OA's are not the issue. Your chemoreceptors send the signal the brain... to breathe. The respiratory center responds in return by changing its firing pattern to alter breathing rhythm and volume. The brain doesn't respond for the you to breathe. The brain stem is not functioning properly... intermitted.

I would go to antihistamine now even with the bleach problem. CPAP machine can induce congestion problems. Also indoor allergies. So you over do it cleaning with bleach? You shouldn't have to wait this long for study results. Email them and demand the polysomnograph.

agreed, but I thought maybe I was missing something.

I was told vauto is better therapy...... why?

do you have a copy of your polysomnograph sleep study results? If not contact the sleep center where you had the study and request one. Then read what your pressures were and go from there. We can guide you from there. Are you on any meds that would interfere with the machine? Find out, google is your friend. I would do a set pressure rather than vauto. Sounds like you are congested and need to address that first. Can you take an antihistamine?

just thought of something... no OA's just centrals alone night before last. I noticed leaks that I never had before... cinched up my mask and it felt better where I had the settings before.

I think I know what the issue is....

I got a new machine due to whining noise and the RT at the DME told me it was probably a bad turbine and I believe it wasn't delivering the amount of air as per the flow rate shows more L/minute during the breath oscillations. I also noticed that a high trigger was a bit much and was wondering if that caused the Centrals? I lowered the IPAP 1 cmh20 and raised the trigger back to high. If the HA still show up I'll raise the IPAP where it was and leave the trigger at high but use the ramp setting to fall asleep before the normal pressures come in.

Here's last nights screenshot...

My pressures have been adjusted way back when I got the machine, but it didn't get rid of Hypopneas, a high trigger did. Good up until this point. This is the second night without Obstructives and Hypopneas with clusters of centrals. Different if the centrals were under 10 seconds.... The breathing cycle, minute ventilation, shows I stopped breathing but as you said a disturbance just before the central, I see, and the minimum of the cycle meaning? Long exhale/pause in inhale? I only see one or two that don't follow a disturbance, I remember now. Needed a refresher... THANKS !
