What is the purpose of a chest seal when used on an open chest wound?

• A. To seal the wound to prevent air from entering the chest cavity, aiding ventilation
• B. To seal the wound to stop bleeding
• C. To seal the wound and deliver antibiotics
• D. To seal the wound to immobilize the chest wall

Answer: (B)

A chest seal over an open chest wound serves to prevent air from being drawn into the chest cavity. It acts as a one-way seal, so air can escape during exhalation but cannot be sucked in during inhalation. This helps prevent a sucking chest wound from developing into a tension pneumothorax and supports overall ventilation. It is not primarily intended to stop bleeding, deliver antibiotics, or immobilize the chest wall.
