Apparatus for supporting and monitoring a person
View Patent ↗A person-support structure includes a control system, an input configured to communicate a first input signal to the control system, and a sensor configured to sense a physiological characteristic of a person supported on the person-support structure. The sensor communicates a second input signal corresponding to the physiological characteristic to the control system. The control system calculates a condition score as a function of the first input signal and the physiological characteristic of the person and compares the condition score to a predetermined threshold. The control system scales at least one of the physiological characteristic of the person and the predetermined threshold as a function of the first input signal.
