WebThe values of VO 2 peak and percentage of the predicted value found in the present study are consistent with reported data, such as those presented in the study by Barron et al, 19 in which COPD patients underwent CPET on a cycle ergometer and presented a mean VO 2 peak of 16.7 mL⋅kg −1 ⋅min −1, representing 69.9% of the predicted value. WebThe American Thoracic Society/European Respiratory Society statement on PFT interpretation advocates the use of a Dlco percent predicted of 80% as the normal cutoff. It also indicates that 79% to 60% of predicted is a mild reduction, 59% to 40% is a moderate reduction, and that Dlco values less than 40% of predicted are severely reduced. 1
