A method and system for analyzing the correlation between left and right lung respiratory impedance

Abstract

The invention relates to the field of medical treatment monitoring, in particular to a method and a system for analyzing correlation between respiration impedance of the left lung and the right lung. The method includes: collecting electrical impedance signals of the left chest part and the right chest part of a testee; subjecting the collected electrical impedance signals to analog-digital conversion to obtain digital signals of electrical impedance of the left chest part and the right chest part; extracting referential characteristic values from the signals of the electrical impedance of the left chest part and the right chest part; analyzing the correlation between the respiration impedance of the left lung and the right lung of the testee. The method and the system have the advantages that the referential characteristic values are extracted according to the signals of the electrical impedance of the left chest part and the right chest part, the correlation between the respiration impedance of the left lung and the right lung of the testee is analyzed according to the referential characteristic values, operation is simple, measured data can be accurately collected quantitatively, good anti-interference effect of the collected signals is achieved, the correlation of the electrical impedance of the left lung and the right lung can be quickly and accurately analyzed, and respiration synchrony of the left lung and the right lung of the testee can be quickly and accurately evaluated.

Description

technical field [0001] The present invention relates to the field of medical monitoring, in particular to a method and system for analyzing the correlation between left and right lung respiratory impedance. Background technique [0002] Assessing the coordination of the left and right lungs can realize the monitoring of breathing during assisted surgery and postoperative rehabilitation. At present, spirometers, ventilators and pneumotachometers are commonly used in clinical practice to directly measure respiration, but these measurement methods often require the cooperation of patients and the operation of professionals, and the respiratory coordination of the left and right lungs cannot be known. Arterial blood gas analysis, recording of airway pressure-volume curves for lung mechanics, and pulmonary plethysmography are all used to track ventilation distribution and guide adjustment of ventilator parameters. However, these techniques only reflect the overall lung function,...
