Abstract

The invention provides a method and device for acquiring central arterial pressure and a computer readable storage medium. The method comprises the following steps of: constructing a calculation model by adopting an artificial intelligence algorithm; obtaining the peripheral arterial pressure waveform of a to-be-tested person by adopting a non-invasive measurement method; and inputting the peripheral arterial pressure waveform of the to-be-tested person into the calculation model for calculation, and outputting the central arterial pressure waveform of the to-be-tested person. Compared with a general transfer function method, the scheme considers the difference between individuals. Non-invasive measurement of the central arterial pressure waveform is realized by the scheme. In addition, compared with a scheme for calculating the central arterial pressure through a one-dimensional arterial model, the scheme does not need to solve the one-dimensional model for many times to adjust sensitive parameters, and a large amount of time is saved.

Description

technical field [0001] The present application relates to the field of central arterial pressure, in particular, to a method, device, computer-readable storage medium and processor for acquiring central arterial pressure. Background technique [0002] In the prior art, the most widely used method for predicting central arterial pressure from peripheral arterial pressure is the general transfer function method (GTF), which is based on the statistical average of large samples to obtain a general transfer function between peripheral arterial pressure and central arterial pressure . However, since the general transfer function is based on statistical average, this method is dependent on the sample data size and sample distribution, and the general transfer function cannot effectively consider the differences between different individuals, and it is difficult to give high-precision prediction results . Contents of the invention [0003] The main purpose of this application is...
