  • Publication number: 20220387741
    Abstract: Automation for a system and/or method detects and/or controls treatment of inspiratory flow limitation. The system may include a flow rate sensor configured to generate a signal representing a respiratory flow rate of a patient. It may include a recording device configured to record the generated respiratory flow rate signal during a diagnosis session. It may include a computing device 7040 configured to detect a degree of inspiratory flow limitation of the patient on the recorded respiratory flow rate signal. The method may include extracting an inspiratory portion of each breath during a detection and/or monitoring session from a respiratory flow rate signal of the patient, calculating a feature vector from each inspiratory flow portion, labelling each feature vector as flow limited or not flow limited, and/or computing a metric based on the labels, the metric indicating the degree of inspiratory flow limitation of the patient during the session.
