Objective The purpose of this study is to evaluate the role of point-of-care ultrasound (POCUS) in assessment of patients with dyspnea in Rapid Response Team (RRT) consultation.53 patients were included and their pre-POCUS, post-POCUS and final diagnoses were documented. Compared with pre-POCUS diagnoses, the accuracy of post-POCUS diagnoses increased significantly from 37.7% up to 79.2%, P＜0.01( final diagnoses as golden standard). When stratified by etiology, we can see that POCUS improved the diagnostic sensitivity and specificity in most of the diseases. But still there were 11 patients in whom POCUS fail to diagnose. And in those POCUS-fail group the mortality seemed higher than in POCUS achieved group.In conclusion POCUS is a convenient and useful diagnostic tool which can improve the diagnostic accuracy of patients with sudden onset of dyspnea in RRT consultation.
