Which statement describes a sucking chest wound?

• A. Hole is about size of a nickel
• B. Wound is on the left chest
• C. Chest wall defect must be 2/3 diameter of trachea
• D. Air prefers to go into the chest instead of the trachea

Answer: (B)

A sucking chest wound happens when there is a hole in the chest wall that allows air to be drawn into the chest cavity during inspiration, creating an open pneumothorax. The defining idea is that air moves into the pleural space through the chest wall defect rather than through the airway. In other words, the wound acts as a conduit for atmospheric air to enter the chest as you breathe in, which can cause lung collapse on the affected side if not managed. The side of the wound doesn’t matter, and there isn’t a fixed size requirement for the hole. There’s no rule about a specific diameter relative to the trachea. So the statement that best describes a sucking chest wound is that air is drawn into the chest through the chest wall defect rather than through the trachea.
