Hydrogen Peroxide (H 2 O 2) breaks down to H 2 O + O or water + a single highly reative oxygen molecule. Ozone =O 3 which breaksdown to O 2 + O. It is this single oxygen molecule that reacts with pathogens.
Then make a separate determination of whether it is related to a medical device. The stage of MDR pressure injuries varies. 1 In one study, 35% of MDR pressure injuries were Stage 1, 32% were Stage 2, 3% were Stage 3 or Stage 4, 24% were unstageable, and 6% were DTPI. 2
Stage II: An open wound. The pressure ulcer may look like a shallow, pinkish red bowl-like wound, or it may appear as an intact or ruptured blister. Stage III: A deep wound. The pressure ulcer has a crater-like appearance. Deep damage may expose a fat layer. The bottom of the wound may have some yellow dead tissue (called slough). Stage IV: Large scale tissue loss. The wound exposes bone, muscle or tendons. The bottom of the ulcer contains slough and/or dark, crusty dead tissue (called eschar).
