pleural space

Definition

Noun:
- The small potential space between the parietal and visceral layers of the pleura: The pleural space is a thin, fluid-filled cavity that separates the two membranes (pleurae) lining the lungs and the chest wall. It is not an actual open space but a potential one, containing a small amount of lubricating fluid to allow the lungs to expand and contract smoothly during breathing.

Usage Examples

Noun:
- A pneumothorax occurs when air enters the pleural space, causing the lung to collapse.
- Doctors drained the excess fluid from the pleural space to relieve the patient's breathing difficulty.
- The pleural space normally contains only a few milliliters of serous fluid.

Advanced Usage

"To enter the pleural space": Refers to air, fluid, or other substances abnormally collecting in this cavity.
- In some injuries, blood can enter the pleural space, creating a hemothorax.
"Pleural space involvement": Used in medical contexts to indicate that a disease process, such as infection or cancer, has spread to or affected this area.
- The scan showed pleural space involvement, indicating the infection had spread.
