With a through wound into the chest cavity, a person may die from suffocation, even if the lungs are not severely damaged. Why is this happening?

When the chest and pleura are damaged, the pressure in the pleural cavity becomes equal to atmospheric pressure, and the suction force of the chest disappears, that is, the lungs cannot normally ventilate during inhalation, and the lack of oxygen causes disruption of the respiratory center.
