thanks for helping Still adjusting
this is the best apnea in the world
1-ahi 5 or less means no significant air leaks yes no
2- read where if your mouth opens with air gushing out (have chin strap)
the pressure is still too high
3-read where sleeping on your side keeps ahi lower then on your back
1. The AHI is based on recorded events. A leak can interfere with an event being sensed. An AHI of less than 5 is just a gauge point set by someone to help quantify severity of apnea. How a person feels is a better determination. I've had nights were my AHI was extremely low because I never entered a deep sleep and I felt it the next day. I've then had nights were my AHI is above the normal and felt great the next day because I really was getting a good deep restful sleep. A problem I've see with the AHI number is it doesn't fully take into account the length(severity) of an event. My CA's usually last about 10 to 11 seconds, which is no big deal. If I had the same number of events but they lasted 30 or longer seconds each, the AHI would be the same number but I would diffidently have a problem. I was guilty of being a number chaser in the beginning until I realized that the AHI value alone was just one attribute to aid in gauging my treatment.
2. An open mouth can show up at higher pressure but can also be caused from a stuffy nose. Usually a pressure induced mouth opening will subside in time as your body becomes acclimated to the pressure. My personal experience is that nasal pillows will better overcome a stuffy nose as opposed a FFM or nasal mask but a FFM addresses my pressure induced openings better. Again, that's just my experience. (Note: Please complete your profile so we may see the equipment that you're using.)
3. Side sleeping does lower AHI. (Please note: I'm really simplifying this)When you sleep your body relaxes. The soft palate area that collapses to cause apnea(OA's and Hyp's) is located in the front of the throat. Sleeping on your back causes gravity to allow this area to drop to the back of your throat, closing off or restricting your airway. While side sleeping, the same thing happens but because the soft palate is trying to fall to the side and not directly to the back, it lessens the airway occlusion, thus reducing related OA's and Hyp's.
I hope this has properly addressed your 3 questions.
