Central Sleep Apnea (CSA) occurs when the brain fails to send the appropriate signals to the muscles of breathing during sleep. One of the common forms of central apnea is known as Cheyne-Stokes respiration. The Cheyne-Stokes respiration is a pattern of breathing characterized by deep inspiratory cycle interchanged with complete cessation of breathing. This form of central sleep apnea commonly occurs in people with congestive heart failure. Central sleep apnea is less common than Obstructive Sleep Apnea (OSA).
