Central sleep apnea
Central sleep apnea is caused by a brief failure of the normal ventilatory rhythm. The International Classification of Sleep Disorders (ICSD-3rd edition) identifies 8 forms of central sleep apnea syndrome. Central sleep apnea may present with insomnia, daytime drowsiness, and fatigue. Some patients complain of nocturnal dyspnea, orthopnea, choking or gasping spells, restless sleep, nonrestorative sleep, and inability to sleep supine.
