Abstract
A patient support apparatus includes a controller operable to determine the true patient weight by detecting the net weight change of the patient supported on the patient support apparatus. The controller is configured to automatically detect and distinguish the addition or removal of non-patient loads from patient-related loads by determining the rate of weight change of each weight event signals. The controller is further configured to determine the net weight change of the patient by automatically updating a net weight of the non-patient loads on the patient support apparatus.
