Central Sleep Apnea is a form of sleep apnea syndromes. Central Sleep Apnea syndrome, or CSA, suggests a “central” failure of breathing in sleep. The brain regulates our breathing involuntarily once we fall asleep. When the brain does not signal the muscles of our chest to breath, this is referred to as central apneas.
Upper Airway Resistance syndrome, or UARS, is a milder form of Obstructive Sleep Apnea syndrome. Similar to OSA, UARS results from a less severe degree of airflow obstruction during sleep. However, the effects on sleep quality and the development of other medical problems from UARS can be just as significant.
