The Application of Point-of-Care Ultrasonography (POCUS) in the Management of Acute Respiratory Distress Syndrome (ARDS) in the Intensive Care Unit

Acute respiratory distress syndrome (ARDS) is a life-threatening condition that necessitates dynamic, non-invasive monitoring for optimal management. Traditional imaging modalities, such as computed tomography (CT), are often limited by radiation exposure and patient instability, particularly in critically ill populations. Point-of-care ultrasonography (POCUS) has emerged as a transformative tool, enabling real-time, multi-system evaluation at the bedside. This protocol highlights five key applications of POCUS in ARDS management: (1) Lung ultrasound (LUS) for assessing pulmonary aeration, edema, and pleural effusion status; (2) Echocardiography to evaluate right ventricular dysfunction and fluid responsiveness; (3) Diaphragm ultrasound to quantify diaphragmatic dysfunction and predict weaning outcomes; (4) Lower extremity venous duplex for early detection of deep vein thrombosis (DVT); and (5) Gastric ultrasonography to optimize enteral nutrition and reduce aspiration risk. By integrating these POCUS modalities, clinicians can tailor personalized ventilation strategies, prevent complications, and ultimately improve patient outcomes. The use of POCUS not only enhances diagnostic accuracy but also supports timely clinical decision-making, making it an indispensable tool in the management of ARDS.
