What is the most immediate treatment for an open pneumothorax?

When air can enter and exit through a chest wound, the immediate goal is to seal that opening so atmospheric air can’t rush into the pleural space during inspiration. An occlusive dressing placed over the wound creates a seal (often used as a flutter-valve if one side is left with a deliberate opening), which helps prevent a dangerous buildup of pressure and the development of a tension pneumothorax. Oxygen is supportive, but it does not stop air from entering the chest. Tourniquets and hemostatic gauze address bleeding on limbs, not the chest wound, so they’re not the immediate action needed here.
