RE: AHI 21 CLEAR AIRWAY 17
Do your other threads go into the nature of your centrals? What is causing your centrals?What other settings have you tried and what were your results? : Without knowing the answers I'd only be gue#ing. I do know what I'd be asking you to do if this is your initial post.
I'm going looking for your other posts and I'm likely to suggest merging your threads.
RE: AHI 21 CLEAR AIRWAY 17
I'm back from reading your other threads.
The UA events were apparently CA events being masked by your large leaks.
Please post a 20 minute view of your central events. I'm expecting to see a waxing waning with CA events at the Nadir/ low points. This pattern shows minimal to no breathing at/near the nadir then successively larger breaths then successively smaller breaths in a cyclical pattern. If I'm right this CO2 driven pattern. What is happening, simple explanation, is your APAP is flushing CO2 out of your system, so much so that your CO2 levels are dropping below your apneic threshold and a central apnea occurs. FYI it is the need to remove CO2 from our system that pro ides our drive to breathe, not the need for oxygen.
Get and post a full copy of your sleep study, charts and tables in addition to the narrative. This will show what centrals you have without CPAP.
Your flow limits are high in every chart you have posted. Flow limits represent resistance in your breathing, think of them as mini hypopneas but untimed. This is significant because I'm going to propose a change that will likely decrease your central apneas by decreasing this flushing of CO2, but it will also cause an increase on your flow limits and other events such as hypopneas and RERAS.
Please set your EPR=0 or off
Don't forget to post a full copy of your sleep study.
Just that for now. Post your results and how you feel and do expect more changes. If this doesn't work you may, only may need an ASV machine which is specifically designed to treat central and complex apnea.
RE: qt9998 Therapy Thread
With predominately central apnea in your therapy results on CPAP it appears you will need to have further evaluation to possibly qualify for ASV. You should request a clinical sleep study to identify the type and severity of apnea. If central apnea is predominate, you will need to complete an additional sleep study for titration to test efficacy of bilevel, moving to ASV if central apnea persists.
You can try turning off EPR to see if this reduces your central apnea index. This is not a substitute for further study, but will show if the bilevel pressure of EPR is causing hypocapnea which increases the CAI in most individuals.
RE: qt9998 Therapy Thread
Had reverse shoulder replacement surgery yesterday but still managed to do my CPAP last night
and again got over 4 hours before waking up.
Attached are the results. Believe it or not my AHI is 0.70 and CA is 0.00. And I forgot to change
the EPR to 0 or anything else before the session. Since I live in California (CA) I guess a CA angel decided to help me out.
Or maybe my old shoulder was in the way. Just joking.
I'm attaching the results.
I'm also attaching my old initial home test results. That's all the doc sent me.

I wish I knew more about the scientific background of sleep apnea so I could respond to you adequately
but what do you think now?
RE: qt9998 Therapy Thread
Following up on my response a few minutes ago, my taking a pain reliever which is an opioid
after surgery may have something to do with the great results. I will be going off of it tomorrow.
RE: qt9998 Therapy Thread
like you said, the opiod probably did calm your response. hope you get a few nights like that.

RE: qt9998 Therapy Thread
Last nite's results even better (see below) but I'm just taking Tylenol today so we'll see
what the results are tonight.
RE: qt9998 Therapy Thread
Results look great. AHI and CA under 2. Now need to keep mask on all night.
That's the hard part as I keep waking up after 3-4 hours.
