INTRODUCTION: Use of ultrasonography in emergency department, critical care and cardiac care units is becoming popular. Patients presenting with respiratory distress to the emergency department can be the really challenging due to the diverse underlying pathology and urgency of appropriate treatment. Emergency ultrasound has been shown to be a valuable adjunct to the standard clinical examination. Research is still limited on how to integrate EUS in the clinical setting and how it impacts diagnostic thinking. The BRIPPED is one among those algorithms used to evaluate patients with respiratory distress OBJECTIVES: To evaluate patients presenting with respiratory distress in the Emergency Department, with BRIPPED SCAN and to find out the Sensitivity, Specificity & Predictive values of BRIPPED SCAN for evaluating the causes of respiratory distress. METHODS: Prospective observational study with a sample size of 130. BRIPPED scan findings and diagnosis and final diagnosis made by treating physician were compared. Statistical analysis was done by SPSS 2018 software. Sensitivity, specificity and predictive values of BRIPPED scan were calculated. RESULTS & DISCUSSION: BRIPPED scan had sensitivity of 97.6 % and specificity of 97.8 % in detecting pulmonary edema, sensitivity of 90.3 % and specificity of 97 % in detecting pneumonia, 90.9 % sensitivity and 100 % specificity in diagnosing pneumothorax, 85 % sensitivity and 99.1% specificity in diagnosing COPD, 77.8% sensitivity and 97.5 % specificity in diagnosing ARDS, 100% sensitivity and specificity in detecting pleural effusion, pericardial effusion and pulmonary embolism. The average sensitivity of BRIPPED SCAN was 92.7 % and average specificity was 98.9 % CONCLUSION: BRIPPED scan had good accuracy in ruling in and out most of the life threatening causes of respiratory distress.
