1. A patient support apparatus comprisinga frame,a surface supported on the frame, the surface including a base and a first sensor,a graphical user interface coupled to the frame, andcontrol circuitry coupled to the first sensor and to the graphical user interface, the control circuitry configured to receive outputs from the first sensor indicative of relative humidity in the support surface, the control circuitry being configured to establish a first moisture level and a second moisture level at a subsequent time from the first moisture level detected based at least in part on the outputs from the first sensor, to accumulate the amount of time spent at the first moisture level and second moisture level detected, to determine if the time spent at the first moisture level exceeds a corresponding first threshold time and to determine if the time spent at the second moisture level exceeds a corresponding second threshold time, the first and second threshold times being greater than zero, and if the time at the first moisture level exceeds the corresponding first threshold time, to display a moisture alert on the graphical user interface in response to the determination that the corresponding first threshold time at the first moisture level has been exceeded, and if the time at the second moisture level exceeds the corresponding second threshold time, to display a moisture alert on the graphical user interface in response to the determination that the corresponding second threshold time at the second moisture level has been exceeded.
