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
NOTE: For wounds deeper into subcutaneous tissue, muscle, or bone (stage III or stage IV pressure ulcers), see the care plan for Impaired Tissue integrity. 3. Monitor site of skin impairment at least once a day for color changes, redness, swelling, warmth, pain, or other signs of infection.
