Abstract
Methods and system to diagnose central sleep apnea of a patient employ a relatively short test, combining few breathing parameters. The test is short in comparison to commonly used time-consuming and complex multi-parameter sleep studies. The patient uses a positive airway pressure device, and follows breathing cues. The occurrence of a central apnea during the delivery of breathing cues may support a diagnosis of central sleep apnea.
