A trapped lung, in the context of lung imaging, refers to a condition where the lung is unable to re-expand fully after pleural fluid drainage due to a visceral pleural peel or restrictive fibrous tissue. This prevents normal lung mechanics, often complicating pneumothorax or pleural effusion management. Ultrasound can visualize this non-expansile lung, aiding diagnosis.
Understanding a trapped lung is crucial for medical professionals, especially in pulmonology and critical care. Ultrasound imaging helps differentiate it from persistent effusions or other causes of lung collapse, guiding appropriate interventions like decortication. Early and accurate identification improves patient outcomes in lung health.
