摘要: The critical issue in considering the diagnosis and management of CSA is to determine physiologic process underlying disorder. includes a pathophysiologically clinically heterogeneous group disorders that can be divided into two main groups on basis awake PaCO2: hypercapnic group, whom disorder related central alveolar hypoventilation or neuromuscular disease, nonhypercapnic there no identifiable common feature these recurrent episodes apnea during sleep withdrawal wakefulness drive breathing. In clinical history dominated by respiratory failure its complications, with disturbance being secondary feature. patients simply an exaggeration, sleep, their Treatment most cases involves mechanical assisted ventilation which very effective reversing failure. contrast, idiopathic characterized tendency hyperventilation. This reinforced arousals, tend propagate CSA. Unlike CSA, relatively benign condition cardiorespiratory not this problematic, but use nocturnal nasal CPAP appears quite effective.
