%X In order to estimate the open-loop gain (G) of arterial baroreceptor reflex in normal human, three models of arterial blood pressure regulation system with different features were developed, from which the equations for calculating G and the relationship between G and hemodynamic variables were derived. In terms of the equations derived, the open-loop gain of the carotid sinus and aortic baroreceptor reflexes can be estimated, respectively, through properly designed tests. The examples of G calculation were given. In addition, the relative contributions of heart rate and peripheral resistance change to G and the effect of input pressure level on G were also analysed.
