the ventilatory equivalent for carbon dioxide (Ve/Vco2);(2) the point at which a systematic rise in end-tidal oxygen pressure (PETO2) occurs without a decrease in the end-tidal carbon dioxide pressure (PETCO2); and (3) the departure of Vco2 from a line of identity drawn through a plot of Vco2 versus Vo2, often called the V-slope method. 8 In a study by Shimizu et al, 9 the VTs calculated by these 3 methods were 68%, 61%, and 65% of VO2max, respectively. The confidence in determining the VT may be increased by having 2 or 3 experienced observers independently calculate this point. When 3 observers used the ventilatory equivalent method, 2 chose the same minute of exercise for VT in 100% of tests, and all 3 agreed in 71%. 10
