What is the primary purpose of applying an occlusive dressing to an open chest wound?

An open chest wound can act like a valve that lets air be drawn into the pleural space with each breath, causing the lung to collapse and raising the danger of a pneumothorax. An occlusive dressing creates a seal over the wound, preventing air from entering the chest cavity. By stopping air entry, it helps keep the lung expanded and reduces the risk of a life-threatening pneumothorax. In some protocols the dressing is taped on three sides to let air escape during exhalation, but the main purpose remains blocking air from getting into the pleural space.
