Fig. 2From: Quantification and physiological significance of the rightward shift of the V-slope during incremental cardiopulmonary exercise testingCoordinate conversion. The second objective method of estimating the representative RtShift. The conventional VO2 versus VCO2 relation is converted to the VO2 versus RtShift relation. The best-fit quadratic equation is obtained and the tangential line to its highest point is drawn. The vertical y value is the representative RtShiftBack to article page
