👉 Caught fluid, also known as pleural effusion, is an accumulation of excess fluid in the space between the lungs and the chest wall, known as the pleural cavity. This fluid can result from various underlying conditions such as heart failure, lung infections, or cancers, and it may appear clear, yellow, or bloody. The fluid buildup can interfere with normal lung function, making breathing more difficult and potentially leading to respiratory complications. It is typically diagnosed through imaging tests like chest X-rays or ultrasounds and may require further investigation to determine its exact cause and appropriate treatment.
