What will happen if your lung is cut off?

If a lung is cut off or severely damaged, it can lead to a life-threatening condition known as pneumothorax, where air enters the pleural space, causing the lung to collapse. This can result in difficulty breathing, reduced oxygen levels in the body, and potentially shock or respiratory failure. Immediate medical intervention is required to treat the injury, which may involve procedures to reinflate the lung or surgical repair. Without prompt treatment, the situation can be fatal.
