Can respiratory parameters be used for non-invasive assessment of the cardiovascular system state by analyzing cardiorespiratory synchronization?
The study demonstrates the potential of using respiratory parameters and cardiorespiratory synchronization for non-invasive assessment of the cardiovascular system state.
This paper presents a method and results of a joint study of human respiration and cardiac activity, based on the authors' long-term research. The results confirm that synchronization between the cardiac and respiratory systems occurs at high frequencies (3–5 Hz) corresponding to eddy airflow. In patients with pathology, phase trajectories reveal additional structures, indicating cardiorespiratory interaction disorders. The obtained data demonstrate the potential of using respiratory parameters for non-invasive assessment of the cardiovascular system state.
