[Regulation of respiration during sleep in congenital central sleep apnea].
We report on 2 children aged 13 and 14 months with congenital central alveolar sleep apnea which showed depression of respiratory drive during sleep resulting from dysfunction of central chemoreceptors. Hypoventilation was found to be more severe during NREM sleep (minimum of alveolar ventilation in stages 3/4) than during REM sleep. During NREM sleep arousal responses to hypoxia proved to be an important factor in influencing the level of alveolar ventilation and in preventing fatal asphyxia.
