Final answer:
A continuous leak of air into the pleural space that builds up pressure and forces the collapsed lung against the heart and the opposite lung is known as a tension pneumothorax, a critical condition requiring immediate medical attention.
Step-by-step explanation:
The condition described in the question, where continuous air leak into the pleural space builds up pressure and forces the collapsed lung against the heart and the opposite lung, is known as a tension pneumothorax. This is a life-threatening medical condition that requires immediate attention. In a tension pneumothorax, the pleural cavity pressure can become so high that it compresses the lung, impairing respiratory function, and can also affect cardiovascular function by compressing the heart and great vessels, potentially leading to shock and rapid clinical deterioration.
This condition occurs when air escapes from the lung and enters the pleural space, creating a one-way valve effect. As the air accumulates, it puts pressure on the collapsed lung and neighboring structures.
