What does the term 'tension pneumothorax' refer to?

A partial lung collapse
A condition where air enters the pleural cavity and cannot escape
A build-up of fluid in the lungs
A heart condition leading to fluid retention

The correct answer is: A condition where air enters the pleural cavity and cannot escape

The term 'tension pneumothorax' refers to a serious condition where air enters the pleural cavity and cannot escape. This occurs when there is a breach in the chest wall or lung that allows air to enter the pleural space but prevents it from exiting, leading to an accumulation of air. As the air builds up, it creates increasing pressure within the pleural cavity, which can cause the lungs to collapse and can also compress vital structures, such as the heart and major blood vessels. This situation requires immediate medical intervention to relieve the pressure, typically through needle decompression or chest tube insertion, to restore normal function and prevent life-threatening complications. Understanding this condition is crucial for EMTs as it is a medical emergency that can rapidly deteriorate a patient's condition.
