在心肺旁路时,通常很重视有效搏动流和无效搏动流之差。必须选取适当的因子。诸如射血间期、蜂值流量等,以达到使毛细血管保持开放並避免血细胞的过度机械损伤所需要的血流波能量成分。同时还必须考虑会显著改变脉搏的动脉管道和主动脉插管的影响。我们研制了一种用于小儿体外循环的、微机控制的、气动驱动的搏动泵。为了达到血流参数的优化,必须认真考察主动脉插管所引起的能量损 In cardiopulmonary bypass, the difference between effective pulsatile flow and ineffective pulsatile flow is usually very much emphasized. You must select the appropriate factor. Such as ejection duration, bee value flow, etc., in order to achieve the blood flow wave energy components needed to keep the capillaries open and to avoid excessive mechanical damage to the blood cells. At the same time must also consider the impact of a significant change in the pulse of the arterial and aortic cannulation. We developed a computer-controlled, pneumatically driven pulsatile pump for pediatric cardiopulmonary bypass. In order to optimize the blood flow parameters, we must carefully examine the aortic cannulation caused by energy loss
