Method of estimating Cardiac Output and apparatus for estimating Cardiac Output

摘要

One embodiment of the present invention provides a method for estimating cardiac output which includes the steps of: calculating an input function for simulating a heartbeat of a subject from a pulse wave signal by the heartbeat of the subject detected on a body surface of the subject; calculating a transfer function for the input function by using a pulse wave as an output function; calculating a time constant of the transfer function; and calculating the cardiac output of the subject by using the time constant. Accordingly, the present invention can estimate the cardiac output with an invasive method.
