Ultrasound has become an integral part for assessment of critically ill patients. It has helped in diagnosing and treating critically ill patients. The added advantage of ultrasonography is that it is a fantastic diagnostic tool that is easily available at the bedside, repeatable, more objective, and has a steep learning curve. It has become fifth vital assessment along with inspection, palpation, percussion, and auscultation. In the current scenario of COVID-19 pandemic, the disease caused by virus ranges from mild influenza-like illness to severe acute respiratory illness (SARI). Among the patients developing SARI, few require hospitalization and might need intensive care management. As a critical care specialist, we need to keep our antenna up to look for other causes for SARI due to non-COVID etiology as well. This article describes algorithmic approach and vital role of ultrasonography while managing patients with respiratory distress.
