The patient reached a maximal work rate of 40 Watts with a peak oxygen consumption (VʹO2) of 12.2 mL·min−1·kg−1. Peak ventilator responses showed a minute ventilation (VʹE) of 119% of her predicted maximum (normal value <80%) with no breathing reserve left. Maximum VʹE also exceeded the maximum voluntary ventilation (MVV). Pred: predicted; AT: anaerobic threshold; VʹCO2: carbon dioxide production; VʹO2/HR: oxygen consumed per heartbeat; PETCO2: end-tidal partial pressure of carbon dioxide; PETO2: end-tidal partial pressure of oxygen; RER: respiratory exchange ratio; VʹE/VʹO2: ventilator equivalents for carbon for oxygen.
