What is the proper dressing technique for an open chest wound to prevent air entry?

Open chest wounds threaten air entering the pleural space with each breath. An occlusive dressing taped on three sides blocks air from getting in while still allowing it to escape, acting like a one-way valve. If you seal on all four sides, air can become trapped and a tension pneumothorax may develop. Dry gauze alone doesn’t seal, and leaving the wound exposed clearly isn’t protective. So the best approach is an occlusive dressing secured on three sides to prevent air entry while permitting ventilation.
