What term refers to an airtight dressing used on penetrating chest trauma?

• A. Chest Seal
• B. Circulatory System
• C. Clinch
• D. Closed Chest Injury

Answer: (A)

An airtight dressing used on penetrating chest trauma is called a chest seal. It’s applied over an open chest wound to form an airtight barrier that stops air from being drawn into the chest cavity, which can worsen a pneumothorax, while still allowing air to escape if pressure builds. In many protocols, chest seals may be vented to control air flow, but the core idea is sealing the wound to prevent air ingress. The other terms don’t describe the dressing used for this purpose—circulatory system is a body system, clinch is not a medical dressing term, and closed chest injury refers to the injury itself, not the dressing used.
