How should an occlusive dressing be applied for a sucking chest wound?

Explanation:
When a chest wound is open to air, air can be sucked into the chest during inspiration and may trap there, risking tension pneumothorax. The right approach uses an occlusive dressing that also acts as a flutter valve. Tape the dressing down on three sides and leave one edge loose. The three-sided seal prevents air from freely entering the wound, while the loose edge lets air escape from the chest as pressure rises, reducing the chance of a dangerous buildup. Sealing all four sides can trap air and worsen pressure, while leaving it uncovered or using a non-occlusive dressing won’t control air movement.
