A non-invasive system for determination of the main cardiorespiratory parameters of the human body.

摘要

A medical device, utilizing a non-invasive method for determining the main cardiorespiratory parameters of a patient's body, and employing a method of operation wherein two or four electrodes are applied to the patient's body in a manner enabling integral bioimpedance measurements of the total body of a patient to be effected. High stability amplitude alternating current is passed through the electrodes into the body so as to obtain an integral impedance curve of the body and derive therefrom simultaneous automatic separation of an active component. The desired cardiorespiratory parameters of the body are calculated from the active component of the integral bioimpedance, using empiric formulae applicable to integral bioimpedance measurements; the calculation being accomplished based on the average data obtained during a respiration cycle. <IMAGE>
