摘要：
Apparatuses and methods for detecting sleep apnea and classifying the events as obstructive sleep apnea (OSA) and/or central sleep apnea (CSA) are disclosed herein. The apparatuses can include respiratory treatment devices that have an auto adjusting algorithm that is able to classify a sleep apnea as CSA or OSA so that an appropriate pressure can be applied to the patient depending on the type of sleep apnea detected. The apparatus comprises a control system configured to: analyse one or more apnea features to make a determination whether a detected apnea event is obstructive sleep apnea or central sleep apnea, wherein the one or more apnea features is derived from the sensed breath by calculating one or more statistical metrics of one or more breath features within one or more predefined breath-windows, each comprising a number of breaths preceding the detected apnea event.
