Cpap therapy adaptation system to mitigate pulmonary hyperinflation and method of operation thereof

A positive airway pressure therapy device, comprising:

• at least one controller;
• a plurality of sensors including at least one electrocardiogram sensor, at least one photoplethysmogram, and at least one flow sensor, the at least one flow sensor configured to determine inspiratory and expiratory flow and form corresponding inspiratory and expiratory flow information, and the at least one ECG sensor configured to sense physiological parameters of a user and form corresponding ECG sensor information;
• the at least one controller configured to:
• control a flow generator to provide therapeutic air assist to the user in accordance with an initial setting mode;
• determine a rise time of expiration based upon the expiratory flow information;
• compare the rise time of expiration to a threshold rise time of expiration value to determine whether the rise time of expiration is less than the threshold rise time of expiration value;
• determine hyperinflation is critical when the at least one controller determines that the rise time of expiration is less than the threshold rise time of expiration value;
• and
• control the flow generator to operate in accordance with a hyperinflation mode to reduce therapeutic air assist to the user when the at least one controller determines that the hyperinflation is critical.
