The right heart perfusion is essential for the normal functioning of the pulmonary circulation. Assessing right heart perfusion provides critical insights into the health status of the pulmonary circulation. Pulmonary blood flow regulation refers to the adjustment of blood supply by the pulmonary artery during changes in right ventricular perfusion to maintain proper right ventricular-pulmonary artery coupling. This study aims to investigate cardiovascular blood flow regulation during right ventricular perfusion using bioimpedance technology and to assess changes in arterial elasticity and flow resistance parameters in the pulmonary circulation. Regional blood flow is assessed using bioimpedance technology, characterizing arterial elasticity and flow resistance parameters through the ratio of diastolic wave amplitude to the depth of the rebound wave and the rate of change of the maximum systolic wave. The discussion focuses on changes in pulmonary blood flow impedance parameters under acute exercise conditions, comparing them with changes in pulmonary blood flow impedance parameters at rest. Compared with the resting state, the changes in arterial elasticity and flow resistance under acute exercise conditions were 77. 78% and 11. 46% , respectively. Statistical analysis revealed significant differences in both parameters before and after exercise (P < 0. 001). Bioimpedance technology effectively detects changes in pulmonary arterial blood flow regulation during pulmonary circulation. By analyzing the pulmonary blood flow impedance waveform to quantify arterial vascular elasticity and flow resistance, facilitating the assessment of right ventricular-pulmonary artery coupling and flow regulation. Bioimpedance technology effectively detects changes in right ventricular flow regulation during pulmonary circulation. By analyzing the pulmonary blood flow impedance graph to quantify the indices of elasticity and resistance, the function of blood flow regulation can be assessed. This method establishes a foundation for non-invasive bioimpedance assessment of pulmonary circulation dynamics.
