I was eleminating flex to see if it would lower my hypopneas. And because it felt like i was increasing pressure without touching the setting and not getting grounded by the DME threatening to tell the doctor.
It think it lowered my hypopneas that nigth. I may fiddle with it a bit when i can stabelize my sleep position.
But by the standards i totally comply. I sleep with the machine everyday from 7 to 8 hours and my ahi is lower than 5. 1.0 AHI.
Also hey , i am Canadian.
whats the difference between Cpap and asv?
I'm sorry Ghandi. I read the first few posts and thought that you were being treated for the obstructive (with BiPAP) but not central apnea (with a servo machine). (That's my story -I'm extra sensitive to that issue!)
I'm so happy that your condition is under control! I love reading about successful treatment!
The respiratory therapist told me that she had lots of patients with central apnea on regular BiPAP. My new sleep doctor said that if central are caused by the therapy (as opposed to 100% plain central sleep apnea) BiPAP will only make it worse. I thought that the respiratory therapist was a little bit wrong, but I don't know the stories of her patients.
CPAP basically has the one pressure which is constant (my ResMed S9 has the EPR setting which can lower the expiratory pressure by 3). BiPAP allows for a large variation between inspiratory and expiratory pressure. BiPAP with ASV (auto servo ventilation) measures your respiration and changes the pressure according to the pattern of how you should be breathing. It follows your normal breathing such that if on the third breath you only inhale 1/4 of normal, it will deliver the other 3/4. So, it is much more than just the two different ppressures of regular BiPAP.
So you have a bipap and it's causing you central apnea episodes?
When i asked for bipap the DME told me they did't used it for sleep apnea. They reacted so strongly, like i was out of my mind to even mention the word bipap. So i backed off.
BiPAP with ASV (auto servo ventilation) seems to be marvellous. I'm just a little more irritated that it wasnt suggested to me at all.
I'm complaning but the cpap changed my life. I'm a new man
