Abstract
A method for characterizing sleep disordered breathing may include identification of at least one of a plurality of predefined airway structural sources associated with a sleep disordered breathing event based on airflow data. In one example, an identification of at least one of a plurality of predefined airway structural sources associated with a sleep disordered breathing event is made based on data indicative of a ratio of a difference between a peak inspiratory airflow rate and a mid-inspiratory airflow rate to the peak inspiratory airflow rate captured during occurrence of the sleep disordered breathing event.
Claims15
A method for characterizing sleep disordered breathing comprising:
- gathering inspiratory airflow data with a sensor during a sleep disordered breathing event;
- and
- determining by a processor, at least one of a plurality of predefined airway structural sources associated with the sleep disordered breathing event based on data indicative of a ratio of (i) a difference between a peak inspiratory airflow rate defined by the inspiratory airflow data and a mid-inspiratory airflow rate defined by the inspiratory airflow data to (ii) the peak inspiratory airflow rate;
- and
- outputting the at least one of a plurality of predefined airway structural sources associated with the sleep disordered breathing event.
A method for characterizing sleep disordered breathing comprising:
- gathering inspiratory airflow data with a sensor during a sleep disordered breathing event;
- determining, by a processor, a selected one of a plurality of predefined airway structural sources associated with the sleep disordered breathing event based on data indicative of a rate of change of inspiratory airflow rate defined by the inspiratory airflow data;
- and
- outputting the selected one of a plurality of predefined airway structural sources associated with the sleep disordered breathing event.
A method for characterizing sleep disordered breathing comprising:
- gathering inspiratory airflow data with a sensor during a sleep disordered breathing event;
- determining, by a processor, at least one of a retropalatal airway dimension or a retrolingual airway dimension associated with the sleep disordered breathing event based on data indicative of a peak inspiratory airflow rate defined by the inspiratory airflow data;
- and
- outputting the at least one of a retropalatal airway dimension or a retrolingual airway dimension associated with the sleep disordered breathing event.
