Review by David Margulies
I'm a 72-year-old physician/scientist trained in internal medicine and a retired member of the faculty of the Harvard Medical School. I began CPAP and monitored my statistics religiously, including all-night oximetry every night. With a full face mask or nasal pillow mask, my AHI was not adequately corrected. Fortunately, I found the original BLEEP device fairly quickly. In the +/-3.5 years since I began using Bleep masks, my AHI averages ~1.5. My oximetry is perfect. As a result of absolute adherence to CPAP enabled by Bleep devices, I'm in excellent health and capable of serious aerobic exercise.
