Abstract: Critical care echocardiography (CCE) plays a vital role in assessing the hemodynamic status of critically ill patients, but there is still a significant deficiency in its clinical application. This study explores the application of echocardiography simulators in CCE training among internists. From May to June 2023, CCE training was conducted for 35 internists in Peking University Third Hospital, which included 1 hour of knowledge teaching and 3 hours of simulated training. The results showed that 33(94.3%) trainees were able to obtain all 5 echocardiography views; the accuracy rate in identifying low blood volume was 100.0%. A simple random sampling method was used to select 16 trainees, who performed echocardiographic on standardized patients one week after the training. The results indicated that all trainees successfully completed the acquisition of echocardiography views on the standardized patients. The training practice demonstrated that the echocardiographiy simulator achieved favorable outcomes in the training of CCE for internists. Trainees could basically master the acquisition of echocardiography views and identification of the echocardiography images within a short period.
