When treating an open chest wound, how should the occlusive dressing be applied?

• A. Occlusive dressing taped on three sides with the gravity side left open.
• B. Occlusive dressing taped on all four sides.
• C. Taped on two sides.
• D. Not taped at all.

Answer: (A)

For an open chest wound, you want to seal the wound while still allowing air to escape so intrathoracic pressure can vent and a tension pneumothorax is avoided. Taping the dressing on three sides accomplishes this: the wound is occluded to prevent air from entering, but leaving one edge open toward the lower (gravity) side lets air escape as needed. If you tape all four sides, air can become trapped and a tension pneumothorax may develop. Taping only two sides doesn’t provide a full seal, and not tape at all leaves the wound exposed and risks contamination and air entry. So, three-sided occlusion with the vent side toward the gravity side is the correct approach.
