Sleep Apnea is a condition where the patient stops breathing during sleep and can be treated by use of a CPAP or BiPAP.  In theory, CPAP/BiPAP should take care of the situation.  But for a number of real world practical reasons often it does not and many users stop use or use infrequently increasing their risk of a fatal heart attack..

In a study by the University of Wisconsin and Boston University School of Medicine published in the American Journal of Respiratory and Critical Care Medicine Vol. 165. pp. 1217-1239, (2002) the authors concluded that even mild obstructive sleep apnea is associated with significant morbidity.  Evidence from the studies indicates that undiagnosed (untreated) obstructive sleep apnea, with or without symptoms, is independently associated with increased likelihood of hypertension, cardiovascular disease, stroke, daytime sleepiness, motor vehicle accidents, and diminished quality of life.

Yale University reported in the Science Daily in May 2007, on a study of 1,132 patients referred for sleep apnea evaluation.  The study showed that sleep apnea, if not treated, over a period of four or five years increases the risk of a heart attack or death by 30 percent. 

Researchers at the Mayo Clinic found that individuals with untreated sleep apnea have an increased risk of having a heart attack during the time they sleep (12am to 6 am).  The July 2008 issue of the Journal of the American College of Cardiology reports that most heart attacks occur between 6am and noon. The study evaluated 92 patients admitted because of a heart attack. Of those with a heart attack between 12am and 6am 91% had sleep apnea.  This important finding speaks for itself.

The author was diagnosed with sleep apnea in November 1999 and has used BiPAP continuously since.  He is a pharmacist, has a PhD in biochemistry and is an attorney practicing chemical/medical patent law.  With his medical-research-invention background he has modified use of the CPAP/BiPAP system, added features and provides many helpful hints he learned by experience over the past decade which makes daily use of CPAP much easier.
