space contains a small amount of fluid (about 10 to 20 mL), with a low protein concentration (less than 1.5 g/dL). Pleural fluid is filtered at the parietal pleural level from systemic microvessels to the extrapleural interstitium and into the pleural space down a pressure gradient.


How much pleural fluid is abnormal?

A pleural effusion is a buildup of fluid between the layers of tissue that line the lungs and chest cavity.

What size pleural effusion should be drained?

The recommended limit is 1000-1500 mL in a single thoracentesis procedure. Preventive strategies include monitoring pleural pressure with a manometer. Larger amounts of pleural fluid can be removed if pleural pressure is monitored by pleural manometry and is maintained above -20 cm water.


Does pleural effusion mean Stage 4?

Stage IV cancer also includes people who have a fluid collection around the lung (called a malignant pleural effusion) caused by the cancer. Stage IV NSCLC cannot be cured, but treatment can reduce pain, ease breathing, and extend and improve quality of life.

What happens if you drain too much pleural fluid?

If large volumes of pleural fluid are drained too quickly, patients can rapidly deteriorate. Their blood pressure drops, and they can become increasingly breathless from the potentially life-threatening complication of re-expansion pulmonary oedema.

Can pleural effusion be benign?

Benign pleural effusions are twice as common as malignant effusions and have diverse causes and manifestations, which often makes them a diagnostic challenge. Differentiating effusions as a transudate or exudate is the first, and often helpful, step in directing investigations for diagnosis and management.
