One issue with patients with chronic wounds, in many cases, is the wound itself is not chronic but a normal healing wound and is either consistently reinjured or reinfected. This is especially so with patients who are incontinent and have wounds below their waist.
A very simple method to prevent reinfection from feces or urinary incontinency is to always expose the skin/bed materials to 254 nanometer ultraviolet when changing dressing or as a routine precaution. It takes only 2 minutes or so but one wound simply wave the V-254 Wound Lamp over the patient's skin and the bed linens to kill any bacteria that was present around the wound itself. This is done after exposing the contaminated wound to the V-254 lamp for approximately 60 seconds.
The V-254 is FDA approved for pathogen irradication on intact skin. The migratory process can be stopped by killing the pathogens so there is nothing to migrate, thus no reinfection which hampers the normal healing processes.

V-254: Hot or Cold Quartz?
Neither.
This is a term used prior to the advent of superior lighting technology using fluoresecent bulbs.
Historically the state of art was to use what was referred to as a "hot/cold quartz" lamp for producing ultraviolet energy in the 254 nanometer range. The "hot" vs. "cold" discussion was about waiting for the lamp to get "hot" which meant a time period before maximum efficiency of emission of ultraviolet energy occurred. During the "cold" period it was advised to not treat the patient as not enough UV energy was coming out of the unit. When it reached it's "hot" period, generally 1 - 2 minutes after turning on, then the physical therapist( UV PT)would begin treatment of the patient's wounds.
The V-254 uses mercury vapor bulbs and there is not a "warm up period" and treatment begins as soon as the lamp is turned on.
