Central alveolar hypoventilation
Central alveolar hypoventilation, a disorder of impaired ventilatory response to hypercapnia and hypoxemia, may be congenital, acquired, or idiopathic. The underlying neurologic disorder involves an absent or reduced response to carbon dioxide resulting in hypercapnia and hypoxemia. Patients exhibit hypoventilation, which is generally worsened in sleep, and they may also suffer from varying degrees of dysautonomia.
