Embodiment Construction

[0052] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0053] According to one aspect of the present invention, a method for calculating central hemodynamic indexes is provided, comprising the following steps, such as figure 1 Shown:

[0054] 1. Use the collected brachial artery blood pressure to calibrate the collected radial artery pulse wave signal to obtain the radial artery pressure waveform;

[0055] 2. According to the pressure waveform of the radial artery, the linear regression model is used to predict the waveform shape of the central artery;

[0056] 3. According to the shape of the central artery waveform, select the transfer function between the corresponding radial artery pressure waveform and the central artery pressure waveform, and use the radial artery pulse wave signal to reconstruct the central artery pressure waveform according to the transfer function;

[0057] 4. Calculate the central hemodynamic...

Abstract

The invention provides a method and a device for calculating central blood flow dynamics indexes, a storage medium and equipment. The method for calculating the central blood flow dynamics indexes includes the steps: calibrating acquired radial artery pulse wave signals by the aid of acquired brachial artery blood pressure to obtain radial artery pressure waveforms; forecasting central artery waveforms by the aid of a linear regression model according to the radial artery pressure waveforms; selecting corresponding transfer functions from the radial artery pressure waveforms to the central artery waveforms according to the central artery waveforms, reconstituting central artery pressure waveforms by the aid of the radial artery pulse wave signals according to the transfer functions; calculating the central blood flow dynamics indexes according to the central artery pressure waveforms. According to the method, the blood flow dynamics indexes such as central artery pressure can be acquired by only extracting radial artery pulse waves, the radial artery pulse waves are stable and easily extracted, and potential safety hazards are omitted when human bodies are tested.

Description

technical field [0001] The invention relates to the technical field of biomedical engineering, in particular to a method, device, computer-readable storage medium, computer equipment and computer program product for calculating central hemodynamic indexes. Background technique [0002] Central arterial pressure refers to the blood pressure in the arteries close to the heart. The European Society of Cardiology (ESC) and European Society of Hypertension (ESH) guidelines in 2003 pointed out that there is a difference between central arterial pressure and brachial artery pressure, and brachial artery blood pressure cannot completely replace central arterial pressure. The Strong Heart study in the United States showed that central arterial pulse pressure measured by non-invasive methods can better predict cardiovascular endpoint events than brachial artery pressure. The heart, kidneys, and major vessels supplying the brain are exposed to pressure in the aorta rather than the bra...
