Central Sleep Apnea (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Central sleep apnea (CSA) or central sleep apnea syndrome (CSAS) is a sleep-related disorder in which the effort to breathe is diminished or absent, typically for 10 to 30 seconds, either intermittently or in cycles and is usually associated with a reduction in blood oxygen saturation. It is a collective term referring to two breathing disorders: Cheyne-Stokes respiration and periodic breathing. CSA is usually due to an instability in the body's feedback mechanisms that control respiration. Adults suffering from congestive heart failure are at risk for a form of central sleep apnea called Cheyne-Stokes respiration. This is periodic breathing with recurrent episodes of apnea alternating with episodes of rapid breathing.
