  • Publication number: 20250160683
    Abstract: A patient support apparatus, such as a bed, cot, stretcher, etc., for a supporting a patient includes an exit detection system adapted to issue an alert when the patient exits from the patient support apparatus. When the exit detection system is armed, a controller onboard the patient support apparatus repetitively determines a current weight supported thereon, selects a variable threshold, compares the current weight to the variable threshold, and issues an exit alert if the current weight is less than the variable threshold. The variable threshold may be selected based on the output of a sensor, which in turn may measure a height of a litter frame of the patient support apparatus and/or the activation of an equipment log control on the patient support apparatus. The controller may be configured to determine a baseline weight reading and to select the variable threshold as a percentage of the baseline weight reading.
