Pleural Space

The potential space between the lungs and the chest wall that normally contains a minimal amount of lubricating fluid.

Key Facts

It is separated into left and right compartments by the mediastinum.
Under normal conditions, it holds less than a teaspoon of fluid.
Accumulation of air, blood, lymph, or pus in this space compromises respiratory function.
It surrounds the lungs but does not directly attach them to the chest wall.

Pyothorax is defined by the pathological filling of this space with pus.

Pathological fluid accumulation in this space directly causes breathing difficulties.
