Abstract:
Idiopathic central sleep apnea during rapid eye movement (REM) sleep is an extremely rare condition and only two cases have been reported so far. We present the case of a male patient who presented with chronic insomnia. Blood gas analysis during wakefulness suggested the presence of hypocapnia. Polysomnographic examination revealed central sleep apnea occurring predominantly during REM sleep. The patient responded well to continuous positive airway pressure (CPAP) at a pressure of 6 cmH2O as well as to acetazolamide therapy.
