thought that it was already well established that CPAP improves quality of life even in mild sleep apnea cases, but i guess not since they're making a big announcement just now: http://www.medpagetoday.com/MeetingCoverage/ATS/14326
Actually they were going to make the announcement earlier but since the INTERNET is getting full they had to wait for a few other ground breaking announcements to fall off the edge before there was space.;)
