This phenomenon has been observed for years, but this study is the first attempt to categorize these people." The study involved a retrospective review of 223 patients consecutively referred to the Mayo Clinic Sleep Disorders Center over one month, plus 20 consecutive patients diagnosed with central sleep apnea.
The investigators found that complex sleep apnea comprised 15 percent of all sleep apnea patients, while 84 percent had obstructive sleep apnea and 0.4 percent had central sleep apnea.
Lichuan Ye, associate professor in the Bouvé College of Health Sciences, thinks about sleep for much longer than that each day. Inflammation is traditionally thought of as a symptom of sleep apnea, but it might actually precede the disorder, potentially opening the door for new ways to treat and predict sleep apnea, according to researchers.
Sleep apnea, left untreated for even a few days, can increase blood sugar and fat levels, stress hormones and blood pressure, according to a new study of sleeping subjects.
But unlike typical obstructive sleep apnea patients, their breathing problem is not completely alleviated by a CPAP (continuous airway pressure) machine, which functions like a pneumatic splint to open a patient's airway.
