Bed load cell based physiological sensing systems and methods

A system for determining a physiological signal of a person supported by a person support apparatus using signals from force transducers is described herein. Force transducers communicate with a controller to transmit signals indicative of weight acting on them. The controller determines blood volum...

More Information
Summary:A system for determining a physiological signal of a person supported by a person support apparatus using signals from force transducers is described herein. Force transducers communicate with a controller to transmit signals indicative of weight acting on them. The controller determines blood volume pulse information from the signals received from the force transducers. Heart rate and respiratory rate information is derived from the blood volume pulse information.
