摘　　要：动脉负荷(arterial load,AL)代表了所有影响心室射血的心外因素,它不仅包含了动脉系统的机械特性,如血管顺应性、外周动脉阻力、主动脉阻抗,还包含了心血管系统的动态特性,如动脉反搏波。动脉负荷诠释了脓毒性休克复苏过程中心输出量(CO)和血压之间的相互变化。深刻理解动脉负荷可以帮助我们更好地理解心血管系统在循环复苏中的表现。本综述将全面分析动脉负荷的生理意义、目前使用的临床指标,以及动脉负荷在脓毒性休克循环复苏中的实际临床价值。Arterial load represents all extracardiac factors that modulate ventricular ejection. It compromises mechanical properties of the arterial system,such as compliance,arterial resistance,characteristic impedance,and also the dynamic characteristics of the cardiovascular system,such as the effects of arterial wave reflections. Arterial load describes the alternation of cardiac output( CO) and arterial blood pressure during septic shock resuscitation. Understanding the arterial load profoundly helps the physician to understand the performance of cardiovascular system in circulatory resuscitation. This review is to integrate the knowledge of the arterial load and to enhanced the understanding of arterial load,which is aimed to detect the underlying processes involved in cardiovascular diseases.
