1. A method for managing a turn protocol for a person,
the method comprising:
providing the turn protocol for the person supported at least temporarily by a support surface, wherein the turn protocol defines a pressurization measure representing a pressurization of a particular body region and at least one pressurization threshold value,
receiving, at a processor, sensor signals from one or more sensors,
identifying, by the processor, based on the received sensor signals, when the person is in a pressurization position corresponding with the particular body region,
monitoring the pressurization measure over time, including (a) increasing the pressurization measure as a function of a first pressurization period spent on the support surface and in the pressurization position and (b) decreasing the pressurization measure, at a first depressurization rate, as a proportional function of a first depressurization period spent on the support surface but out of the pressurization position;
comparing the monitored pressurization measure to the at least one pressurization threshold value over time;
outputting turn protocol alerts based on the comparison;
detecting, based on the received sensor signals, the person exiting the support surface and subsequently returning to the support surface, defining a second depressurization period spent off the support surface; and
decreasing the pressurization measure, at a second depressurization rate, as a proportional function of the second depressurization period spent off the support surface;
wherein the second depressurization rate is greater than the first depressurization rate.
