摘要
Despite efforts to develop treatment technology for cardiac arrest (CA),CA incidence and mortality rates are still high.^([1,2])A recent study of CA patients in emergency departments revealed that the incidence of CA is increasing annually,and the in-hospital survival rate of CA patients is only approximately 28.7%.^([3])Echocardiography has been widely used as an important monitoring tool in critical care and helps to identify the cause of shock,monitor hemodynamics,and guide fluid therapy utilization.^([4])One study reported that approximately one-third of patients underwent formal echocardiography during hospitalization in the intensive care unit (ICU).
