用参数SV/P_p探讨了家兔颈动脉窦压力感受反射时动脉顺应性的变化。加压反射时,SV/P_p减小(P<0.05),提示动脉顺应性减小;减压反射时,SV/P_p稍增大(P>0.05),顺应性变化无意义。文中根据反射时MBP、TPR、CO、SV、HR及P_P等参数的变化,分析了动脉顺应性变化的可能机制。
The parameter SV / P_p was used to investigate the change of arterial compliance in carotid sinus baroreflex. SV / P_p decreased (P <0.05), suggesting that the arterial compliance decreased when decompression reflex, SV / P_p slightly increased (P> 0.05), compliance changes meaningless. According to the changes of MBP, TPR, CO, SV, HR and P_P, the possible mechanism of arterial compliance was analyzed.
