In applying the negative pressure system, why are holes cut in the drape over the wound?

• A. To expose the wound bed and secure the sponge
• B. To vent air to the atmosphere
• C. To facilitate antibiotic application
• D. To reduce suction

Answer: (A)

Negative pressure wound therapy relies on a sealed dressing that transmits suction evenly to the wound bed through a foam or gauze layer. Cutting holes in the drape over the wound creates openings that allow the sponge to be positioned directly on the wound surface and secured in place. This fenestration ensures the wound bed is in direct contact with the suctioned dressing, prevents air gaps that would diminish suction, and helps the dressing stay in place as it conforms to the wound. Venting to the atmosphere or applying antibiotics isn’t the purpose of these openings, and reducing suction would defeat the therapy.
