MCQ IN MEDICINE

Detailed explanation-1: -An abnormal collection of air in the space between the thin layer of tissue that covers the lungs and the chest cavity. This can cause all or part of the lung to collapse. A pneumothorax may be caused by a chest injury, certain medical procedures, lung disease, or other damage to lung tissue.

Detailed explanation-2: -A pneumothorax is a collection of air outside the lung but within the pleural cavity. It occurs when air accumulates between the parietal and visceral pleura inside the chest. The air accumulation can apply pressure on the lung and make it collapse.

Detailed explanation-3: -A collapsed lung occurs when air escapes from the lung. The air then fills the space outside of the lung between the lung and chest wall. This buildup of air puts pressure on the lung, so it cannot expand as much as it normally does when you take a breath. The medical name of this condition is pneumothorax.

Detailed explanation-4: -A pneumothorax is when the lung has collapsed due to air entering the space around your lungs (known as the pleural space). Air can enter the pleural space through an opening in your chest wall or in the lung. Air in the pleural space creates an increase in pressure around the lung and causes it to collapse.
