The Authors have being studying the monitorage of the phases of skin expansion using non-invasive methods for oxymetry and fluxymetry. For the oxymetry they used a Radiometer TCM 222 and for the fluxymetry a TSI/BPM 403 soft laser helium-neon. The results of both, after the injection of a saline volume that is the 10-20% of the expander's capacity, evidence, during the first two minutes, a diminution to the value of 0 of the oxygen and capillary flow and, during the following 30 minutes, a return to 90% of the basal values.
