Detecting, identifying and alleviating causes for pressure burden using positive airway pressure devices

A computer implemented method of controlling a positive airway pressure device for providing ventilation support therapy, wherein the positive airway pressure device is configured to deliver pressurized air to a subject, during subject inspiration and expiration, according to a therapeutic pressure protocol, the method comprising:

• receiving physiological data from a physiological sensor arrangement, wherein the physiological data comprises chest movement data and abdominal movement data;
• running a detection algorithm configured to:
• determine an expiration pressure burden based on the chest movement data and the abdominal movement data,
• perform a comparison of the chest movement data and the abdominal movement data to at least one threshold,
• determine whether the expiration pressure burden is indicative of hyperinflation based on the comparison;
• running a pressure adjustment algorithm, in response to determining the expiration pressure burden is indicative of hyperinflation, wherein the pressure adjustment algorithm is configured to generate a pressure adjustment instruction for adjusting the therapeutic pressure protocol based on the determined expiration pressure burden;
• and
• outputting the pressure adjustment instruction to adjust the therapeutic pressure protocol based on the determined expiration pressure burden.
