Abstract:
1. A method for reducing the amount of data required to analyze a hemodynamic signal, comprising using a microprocessor to: (a) in response to detecting a specific event associated with a cyclical body function, continuously sample the hemodynamic signal during a window following the detecting of the specific event, to thereby produce a plurality of samples, wherein the window is shorter than a cycle associated with the cyclical body function and wherein the window includes a minimum and a maximum of the hemodynamic signal produced within the cycle associated with the cyclic body function; (b) repeat step (a) a plurality of times such that a plurality of samples is produced for each of a plurality of said windows; and (c) analyze the hemodynamic signal based on the plurality of samples, wherein said analyzing step comprises averaging the plurality of samples produced for each of the plurality of said windows to thereby produce an average value for each of said windows.
