A, The PICO NPWT pump is lightweight (80 g) and measures 64 mm × 68 mm × 21 mm. It delivers −80 mm Hg and lasts for 7 days. There is no exudate canister and it is battery-powered. Exudate evaporates from the upper surface of the multilayer NPWT dressing, which transmits negative pressure across the surface of the wound. B, A patient from the trial randomized to receive PICO to the right breast following the reduction procedure. The dressing covers the entire lower incision, the T-junction, and much of the vertical incision except the nipple.
