Abstrakt		The study tests the acute and chronic effects of electrical stimulation on transcutaneous partial oxygen tension (pO2) in volunteer patients with ischemic and pressure ulcers. No patients in the study experienced ischemia in the skin around their wounds. No significant changes in pO2 were detected in the skin surroundig the wounds when acute electrical stimulation (lasting 1 hour) was administred. Chronic electrical stimulation of ischemic ulcers treated with AC current (lasting up to 9 weeks) caused a significant increase of pO2 in that area. There were no significant changes of pO2 in patients without critical ischemia or in the control group during the study. It is supposed that the increase of pO2 during electrical stimulation in patients with ischemic ulcers was caused by changes in the microcirculation. Electrical stimulation may have beneficial effects on the microcirculation, which is most affected during ischemia. It could be assumed that hypoxia of the release of metabolites during electrical stimulation due to insufficient blood flow and lack oxygen represent a stimuli for capillary growth.
