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
Pressure sores are described in four stages: 1  Stage 1 sores are not open wounds. The skin may be painful, but it has no breaks or tears. 2  At stage 2, the skin breaks open, wears away, or forms an ulcer, which is usually tender and painful. The sore expands into deeper layers of the skin.
