A plenum space is a part of a building that can facilitate air circulation for heating and air conditioning systems, by providing pathways for either heated/conditioned or return airflows, usually at greater than atmospheric pressure.
Pneumothorax is defined as a collection of air that is located within the thoracic cage between the visceral and parietal pleura (image 1). Air can enter the pleural space through a leak in either pleural surface. It may flow freely within the chest or be loculated by fibrous bands or other tissues.
