A casualty with a penetrating chest wound is best managed by applying a chest seal to treat which wound type?

• A. Open chest wound
• B. Closed chest wound
• C. Rib fracture
• D. Skin laceration

Answer: (C)

Chest seals are used for an open chest wound from a penetrating injury. The seal acts as an occlusive barrier to stop air from entering the pleural space during inhalation, which helps prevent a tension pneumothorax; vented designs can allow air to escape without letting air enter. So, the wound type best treated with a chest seal is an open chest wound. A rib fracture isn’t an external chest opening, a closed chest wound has no open chest defect, and a skin laceration involves only the skin.
