Hemodynamic parameter detection method, terminal equipment and system

Abstract

The invention provides a hemodynamic parameter detection method, terminal equipment and a hemodynamic parameter detection system. The detection method comprises the following steps: acquiring a first pulse wave signal, and preprocessing the first pulse wave signal to obtain a second pulse wave signal; inputting the second pulse wave signal into a trained multi-scale sensing network, and extracting a first feature and a second feature from the second pulse wave signal; the first feature comprises blood pressure fluctuation information and heartbeat rhythm information, and the second feature comprises elastic fluctuation information of a blood vessel wall and pressure peak information of the blood vessel wall; based on a multi-scale sensing network, the first feature and the second feature are aggregated, a plurality of haemodynamic parameters are output, and the haemodynamic parameters are detected in real time; the hemodynamic parameters comprise systolic pressure, diastolic pressure, cardiac output and peripheral vascular resistance. By means of the hemodynamic parameter detection method, global features and local features in pulse wave signals are captured, and multi-dimensional hemodynamic parameters are detected in real time.
