Claim One:
1. An apparatus for detection of asynchrony between a synchronized respiratory treatment and a respiratory cycle, the apparatus comprising: a memory containing data representing a feature set of detection values derived from signals of at least one sensor coupled with a respiratory treatment apparatus, in which the feature set of detection values includes a plurality of features as respective individual parameter detection variables derived from a pattern of flow indicated by the signals; and a controller of the respiratory treatment apparatus, wherein the controller is configured to access the data, and to control: a comparison of the individual parameter detection variables respectively of the plurality of features of the data of the feature set of detection values respectively with a set of associated thresholds for the individual parameter detection variables of the memory, the set of associated thresholds for the individual parameter detection variables being from other than the signals; a determination of an occurrence and type of an asynchrony event between the respiratory treatment apparatus and a patient respiratory cycle based on the comparison, wherein the determination of the occurrence and type of the asynchrony event identifies time of occurrence of a distinct asynchrony event of a plurality of distinct asynchrony events comprising at least two distinct events of (a) a post-triggering effort event, (b) a double triggering event, (c) a late triggering event, (d) an auto triggering event, (e) an early cycling event, and (f) a late cycling event; and a generation of an output representing the occurrence of the asynchrony event, in which the controller is configured to control the respiratory treatment apparatus based on the determination of the occurrence and type of the asynchrony event.
