Overall microcirculation function evaluation of lung tissue and visual presentation method

Abstract

The invention provides an overall microcirculation function evaluation of lung tissue and visual presentation method, which comprises the following steps: capturing lung tissue microcirculation oxygen parameters and microcirculation hemodynamic parameters, cleaning lung tissue microcirculation function data, and finally, carrying out general microcirculation framework and wavelet analysis method to visually present the overall microcirculation function of the lung tissue. Compared with the prior art, the whole microcirculation function of the lung tissue is evaluated more comprehensively and completely from the two aspects of lung tissue microcirculation hemodynamics and microcirculation oxygen; meanwhile, null value data and abnormal data from instrument firmware and optical components are eliminated through a microcirculation function data cleaning module; finally, the lung tissue microcirculation function data is visually presented, the lung tissue microcirculation function state can be deeply analyzed and excavated, and the scientificity of lung tissue microcirculation function characteristic display is improved.

Description

technical field [0001] The invention belongs to the technical field of data analysis, and in particular relates to a method for evaluating and visualizing the overall microcirculation function of lung tissue. Background technique [0002] The microcirculation of biological tissue is mainly responsible for the transport and exchange of oxygen and nutrients through microvascular blood perfusion, and plays a key role in maintaining the normal physiological function of biological tissue and the stability of the internal environment. [0003] Pulmonary microcirculation is a term of respiratory disease published in 2018 (the first edition of "Terms of Respiratory Disease"). Pulmonary microcirculation refers to blood circulation between pulmonary arterioles and pulmonary venules. Including pulmonary arterioles, pulmonary capillaries and pulmonary venules, etc., because the total cross-section of pulmonary microvessels is significantly enlarged, the blood flow velocity is obviously...

AI Technical Summary

Problems solved by technology

Invasive exposure of lung tissue severely affects the accuracy of pulmonary microcirculation function measurements

[0008] Indicators are single and incomplete

Existing technology can only measure a single microcirculation function index, and cannot fully focus on the microhemodynamics of the lung tissue microcirculation and the oxygen index of the lung tissue microcirculation

[0009] There are outliers and noise interference

Affected by the respiratory properties of lung tissue and the complexity of biological tissue microcirculation function data, most of the lung tissue micro-blood perfusion and blood flow velocity measured by existing technologies have abnormal values

The existing technology does not have a microcirculation function data cleaning process including outlier processing and boundary value adjustment. The above-mentioned objective shortcomings further affect the scientificity and accuracy of the overall microcirculation function evaluation and visualization of lung tissue.
