Cardiopulmonary coupling feedback method and device

Abstract

A cardiopulmonary coupling feedback method comprises the steps that firstly, the cardiopulmonary coupling strength of an examinee is obtained by carrying out coupling analysis on cardiovascular signals and respiratory signals of the examinee; secondly, movement indicating signals are output to the examinee according to the cardiopulmonary coupling strength of the examinee so as to improve the cardiopulmonary coupling strength of the examinee. By means of a cardiopulmonary coupling feedback device and the cardiopulmonary coupling feedback method, a user can carry out specific movement under the guidance of the cardiopulmonary coupling strength to improve the cardiopulmonary coupling strength constantly. The synergic efficiency of the cardiopulmonary system is improved.

Description

technical field [0001] The present invention relates to biofeedback, and in particular to cardiopulmonary coupled feedback. Background technique [0002] Cardiopulmonary coupling refers to the internal coordination mechanism and function between the cardiovascular system and the respiratory system, also known as cardiopulmonary interaction, and its research involves a wide range of physiological, pathological and clinical application fields. There is a clear coupling relationship between the cardiovascular system and the respiratory system, such as the heart rate speeds up during inhalation and slows down during exhalation; the amplitude of the ECG signal also shows obvious amplitude modulation with the thoracic breathing movement; The amplitudes of blood pressure and pulse wave signals are also modulated by respiratory motion, exhibiting changes in amplitude with inspiratory and expiratory motion. On the one hand, the cardiopulmonary coupling phenomenon can be used to obta...

Problems solved by technology

[0004] Current biofeedback technology and devices often measure single signals, and biofeedback training is carried out only from the perspective of changes in a single physiological parameter, such as electromyography, electroencephalography, skin electricity, heart rate, blood pressure and other feedback instruments. To a certain extent, it can reflect the psychological and physiological changes of the human body, but a single-dimensional analysis often cannot reflect the internal relationship between systems

The human body is an open and complex giant system, and the correlation between systems is a direct and important information reflecting the state of the system. However, in the field of biofeedback, information on the interaction or coupling relationship between systems has not been effectively utilized.

There is another disadvantage of single physiological parameter feedback, such as heart rate feedback. Simply looking at the amplitude modulation process of heart rate and breathing cannot reflect the best training effect, because when the amplitude of heart rate and breathing oscillates to a certain extent, the relationship between heart and lung Decreased coupling and coordination, especially for some patients with cardiopulmonary diseases, such as COPD patients, asthmatics, heart failure patients, etc., not only can not achieve the purpose of regulating and treating the disease, but may induce the risk of cardiopulmonary disease attack
