A wide range of baroreflex stimulation does not alter forearm blood flow. Academic Article uri icon


  • The contribution to the regulation of forearm blood flow (FBF) by different baroreceptor populations has previously only been studied over a limited range of stimuli. Therefore, FBF and R-R interval were recorded during neck suctions and neck pressures ranging from -60 to +40 mmHg. The change in R-R interval (DeltaR-R) during neck suction was significantly increased at each stage when compared to the control ( P<0.05). DeltaR-R did not show any significant change during any of the neck pressure stages ( P>0.05). Suction or pressure applied to the neck did not elicit any significant changes in FBF when compared to the control ( P>0.05). These data show that widening the range of applied stimuli to carotid sinus baroreceptors does not induce a change in FBF. However, the small transient changes reported previously cannot be discounted.
