Approaches to determining health of a living body through analysis of the pressure of inflatable chambers of a pressure-mitigation device

A method performed by a controller that has an egress interface to which a pressure-mitigation device, on which a living body is situated, is fluidly coupled and that is responsible for controlling airflow into a chamber of the pressure-mitigation device by actuating a valve, the method comprising:

• obtaining, from a transducer that is situated in a flow channel defined between the valve and the egress interface, an electrical signal that is representative of pressure within the flow channel, and therefore is also representative of pressure of the chamber of the pressure-mitigation device;
• examining the electrical signal to identify changes that are indicative of movements of the living body;
• and
• estimating a value for a characteristic of the living body based on the movements of the living body.

A non-transitory medium with instructions stored thereon that, when executed by a processor, cause the processor to perform operations comprising:

• obtaining multiple series of values in temporal order,
• wherein each series of values is indicative of pressure of a corresponding one of multiple chambers of a pressure-mitigation device situated beneath a living body over time, and
• wherein each series of values is generated by a corresponding one of multiple transducers that are located in a controller to which the pressure-mitigation device is fluidly coupled;
• characterizing motions of the living body based on an analysis of changes in the multiple series of values;
• applying, to the motions, a computer-implemented model that is trained to detect a motion pattern that is indicative of an occurrence of a medical event;
• and
• in response to a determination that an output produced by the computer-implemented model indicates that the medical event has occurred, causing a notification to be presented to indicate that the living body is in need of care.
