  • Method and an Apparatus for Determining Hemodynamic Status
    Publication number: 20220273181
    Abstract: A device and a method thereof for determining a hemodynamic state of an individual from a magnitude of a perfusion signal or a signal which is a measure of a volume of blood in the thoracic cavity of the individual, wherein the control device is configured to receive a first signal and a heart rate signal, divide the first signal into frames, wherein a frame length is determined from an oscillation period of the heart rate signal, and determine a magnitude of the first signal from at least two frames, so as to obtain a more reliable magnitude of the first signal.
    Type: Application
    Filed: May 20, 2022
    Publication date: September 1, 2022
    Inventors: Darrel Francis, Matthew Shun-Shin, Daniel Keene, Zachary Whinnett
