In the past, it was believed that ultrasound assessment of the lungs was not possible due to the presence of air, which hindered the visualization of the lung tissue. However, over time, various artifacts generated by ultrasound interactions with different structures within the chest, including tissues, air, and fluid, have been studied and increasingly utilized to evaluate and comprehend pulmonary diseases. The objective of this review article is to assess the effectiveness of point-of-care ultrasound (POCUS) in patients with lung disease. POCUS has emerged as a valuable tool in managing patients with lung disease. It enables real-time visualization of lung structures, evaluation of lung pathology, and guidance for various procedures. POCUS has demonstrated promise in diagnosing and monitoring conditions like pneumonia, pleural effusion, and pneumothorax. Furthermore, it has been utilized to assist in interventions such as thoracentesis and chest tube placement, resulting in improved patient outcomes. This review article offers a comprehensive overview of the current evidence regarding the use of POCUS in patients with lung disease. It emphasizes the potential advantages of POCUS in enhancing diagnostic accuracy, facilitating timely interventions, and reducing the necessity for more invasive procedures. The findings of this review article contribute to the expanding body of literature supporting the integration of POCUS into routine clinical practice for patients with lung disease.
