Anaerobic skin metabolism in healthy men estimated with transcutaneous PCO2electrode

Abstract
It is shown how the anaerobic energy production of the skin may be calculated from a transcutaneous PCO2 [partial pressure of O2] curve obtained at 37.degree. C during arterial occlusion. Healthy volunteers (30) were studied 3 times. The interindividual differences in estimated ATP production were highly significant, but the intraindividual ones were not. The grand mean of the triplicate experiments of all the 30 subjects was an ATP production rate of 0.33 mmol .cntdot. l-1 .cntdot. min-1. Assuming no initial metabolic acidosis or alkalosis, the estimated mean extracellular fluid pH was 7.33 before and 7.26 after 4 min of stasis.
