Problems solved by technology

At present, the relatively accurate measurement method of cardiac output in the medical field generally uses Doppler ultrasound and other expensive and complicated equipment for measurement, or auscultates the heart sound signal by a doctor, and then calculates the cardiac output based on the heart sound signal. These methods have high requirements on medical equipment or personnel, and cannot be implemented in household

Abstract

The invention relates to a cardiac output measurement method and device, computer equipment and a storage medium. The cardiac output measurement method includes the steps that at least two sets of impedance signals of a subject are acquired, wherein each set of impedance signals includes a plurality of impedance signals of a same body segment of the subject; feature extraction is performed on eachset of impedance signals to obtain a measurement parameter and a second measurement parameter corresponding to each set of impedance signals; according to the first measurement parameter and the second measurement parameter corresponding to each set of the impedance signals, the candidate cardiac output corresponding to each set of the impedance signals is determined; and target cardiac output isdetermined based on each candidate cardiac output. The cardiac output measurement method and device, computer equipment and the storage medium can be used for measuring more accurate cardiac output.

Description

technical field [0001] The present application relates to the medical field, in particular to a method, device, computer equipment and storage medium for measuring cardiac output. Background technique [0002] Cardiac output is an important parameter to reflect the heart function of a patient. It is very important to understand the pumping function of the heart, calculate the relevant hemodynamic indicators, and guide clinical treatment, especially in the monitoring of heart function in critically ill patients and heart disease patients. the value of. At present, the relatively accurate measurement method of cardiac output in the medical field generally uses Doppler ultrasound and other expensive and complicated equipment for measurement, or auscultates the heart sound signal by a doctor, and then calculates the cardiac output based on the heart sound signal. These methods all have high requirements on medical equipment or personnel, and cannot be realized in household equi...
