Abstract

The invention provides a hemodynamics parameter obtaining method and device, and belongs to continuous noninvasive hemodynamics monitoring. The method comprises the steps of collecting electrocardiosignals and pulse oximeter signals of a target user; preprocessing the electrocardiosignals and the pulse oximeter signals; detecting waves Q and R of the processed electrocardiosignals, and performing feature point identification on the preprocessed pulse oximeter signals; according to the waves Q and R of the detected electrocardiosignals and feature points of the pulse oximeter signals, obtaining a plurality of hemodynamics parameters. By performing systematic and scientific logic analysis on the electrocardiosignals and pulse oximeter signals generated in daily life such as resting and moving of the target user, the multiple hemodynamics parameters are accurately obtained; compared with existing continuous noninvasive hemodynamics monitoring, the method is accurate in measurement, suitable for an operating room, intensive care, daily living, exercise, extreme exercise and other special requirements, safer, more comfortable and higher in anti-jamming capability.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and device for acquiring hemodynamic parameters. Background technique [0002] Hemodynamics is a discipline that studies blood flow and deformation of the heart and blood vessels. The existing hemodynamic monitoring methods are mainly divided into two categories: invasive monitoring and non-invasive monitoring. [0003] The existing invasive monitoring can obtain multiple hemodynamic parameters, but it is inconvenient to use, expensive, and there is a certain risk of infection, which brings pain to the subjects. In the existing non-invasive monitoring, impedance cardiography is mainly used, which requires disposable electrodes to transmit low-amplitude high-frequency current through the chest cavity. The structure of the equipment is complex, and there is a certain dose of electromagnetic radiation to the monitored person, which damages the health of the monitor...
