Circulatory Effects on Breath: Left Ventricle Function Affects on Damping of Breathing Control Signal

Abstract

PURPOSE: Based upon the our brand new theory of “A Dynamic Model Integrates Multi-systems for Breathing Control”, lung breath generated signals of O2, CO2 and [H+] oscillations to trigger the next breath via fast sensors (carotid and aorta) and the slow central medullary censor control the “gain” of breath with longer time delay in collaboration with an integrative respiratory center. We hypotheses that left heart function effecting on the breath via the damping breathing control signals (magnitudes of arterial O2 and CO2 oscillation from alveoli) is one mechanism of heart/lung interconnection.
