Re: UARS: A Critical Link to Optimizing PAP Therapy Results

Are you using your APAP in a range of pressures? If so, maybe the pressure changes are actually what are disturbing your sleep and leaving you unrested. APAPs are programmed to increase pressures on Flow Limitations and Snores. So, maybe when you enter a sleep stage and your breathing changes, the machine thinks you're needing more pressure and it bumps you out of your needed sleep stage and into lighter ones.ofarchesandants wrote:KHVN (and others) Please forgive this email if your query was answered as i'm looking at year old posts and haven't read them all yet. However what was said in Dr. Krakow''s email but not reiterated is that a primary function of bilevel in UARS is to prevent arousals caused by flow limitation. In other words the brain of someone, oh let's say like me, who does not snore and has few to no apneas and also few hypopneas, pulse oximetry that remains mostly in the high 90's but is also incredibly sleepy every day is due to a hypersensitivity of that brain to the slightest flow reduction. In other words the flow reduction is minor but the brain perceives it as a major threat, thus causing an arousal. So in that case the slightest pressure needed to prevent flow reduction would be preferable over a greater pressure that is designed merely at keeping the airway open because that greater pressure would also cause arousals. So the point here is to eliminate "AROUSALS" with the least amount of external stimuli and "NOT" to simply keep the airway open. If the airway is kept open but a high pressure is causing arousal and thus preventing adequate sleep you have not only not helped the problem but you may have made it worse.
