Abstract: A system and method of identifying a patient interface device change in a pressure support system having a controller based on a mask and a headgear worn by a user. A set of force sensors and strap distance sensors are associated with the mask and the headgear such that a controller is able to assess current operational parameters of the mask and headgear. The controller further determines if there is a difference in the current operational parameters when compared to prestored operational parameters. The controller then assesses whether or not the determined change in the operational parameters indicates that the mask worn by the user has been changed.

Abstract: The invention provides 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 comprises receiving physiological data from a physiological sensor arrangement; running a detection algorithm to determine an expiration pressure burden based on physiological data; running a pressure adjustment algorithm, 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. In another aspect, the invention provides a ventilation support system.

Abstract: A system and method for generating a non-linear model of the airway of a sleeping subject is provided. The system comprises an interface adapted to obtain an airway model configured to represent respiratory airflow in the airway of the subject; a movement sensor arrangement configured to detect movement of the chest or abdomen of a subject; an airflow sensor arrangement configured to detect an airflow in the airway of the subject; and a processor arrangement. The processor arrangement is configured to determine a movement pattern from detected movement of the chest or abdomen of the subject; determine an airflow pattern from detected airflow in the airway of the subject and modify the airway model based on the movement pattern and the airflow pattern so as to generate a subject-specific piecewise linearized non-linear airway model for the subject representing respiratory airflow in the airway of the subject in a sleep state. The system may be used for patient stratification and sleep apnea therapy selection, wherein sleep apnea therapy selection covers the primary selection of a single or combination therapy, as well as the dynamic adaption of the selected therapies during sleep.

Abstract: In an embodiment, a control system is described. The control system controls a respiratory support system for supplying therapy gas to a subject. The control system comprises processing circuitry communicatively coupled to an interface for receiving an indication of a combination of the subject's head orientation and torso orientation. The indication is based on orientation data provided by a sensing system configured to detect the subject's head orientation and torso orientation. The control system further comprises a machine-readable medium storing instructions. When executed by the processing circuitry, the instructions cause the processing circuitry to identify, from parameter information associated with each of a set of different combinations of head orientation and torso orientation, a parameter value of the therapy gas for the respiratory support system to use in supplying the therapy gas to the subject for the indicated combination of the subject's head orientation and torso orientation. The respiratory support system is caused to supply the therapy gas with the identified parameter value.

Abstract: A sleep therapy system comprises a sensor arrangement for detecting physiological parameters of a subject, a detection system for detecting a sleeping position of the subject and an alert system for instructing a change in sleep position of the subject. From the monitored physiological parameters, fluid accumulation is identified in a region of the body of the subject. The alert system is controlled to instruct a change in sleep position thereby to reverse the fluid accumulation.

Abstract: A system and method for generating a predictive indicator representing a difference between a PAP titration sleep session and at least one conventional sleep session. Data relating to the subject's sleep and to sleep influencing factors is obtained for both the PAP titration sleep session and the conventional sleep session, and is processed to identify any differences between the PAP titration sleep session and the conventional sleep session. A predictive indicator indicative of whether the identified difference(s), if present, satisfy a first predetermined condition is generated.

Abstract: A system and method for controlling a sleep disordered breathing (SDB) therapy device. Signals responsive to a subject's breathing and baroreceptor-initiated changes in sympathetic activity of the subject, while the subject is undergoing therapy using the SDB therapy device, are obtained and processed to detect a change in sympathetic activity. For changes in sympathetic activity exceeding a predetermined threshold, a determination as to whether the change is chemoreceptor-initiated or baroreceptor-initiated. A control signal for controlling the SDB therapy device is generated according to whether the change is chemoreceptor-initiated or baroreceptor-initiated.
