Figure Lengend Snippet: Cardiopulmonary exercise testing (CPET) before treatment; Vertical dashed lines in panels 1–3 and 6, 8, and 9 indicate the beginning of loadless pedaling, the start of loaded exercise and of the beginning of the recovery period. Horizontal dashed lines in panels 2, 3, 5, and 6 indicate the peak predicted values. Plot 1: ventilation in liter per minute (VE, L/min) versus time (minute); Plot 2: Heart rate (HR) and O 2 pulse (Oxygen uptake [VO 2] /HR) versus time; Plot 3: VO 2 , carbon dioxide output (VCO 2 ) in L/min and work rate (watts) versus time (minute); Plot 4: VE/versus VCO 2 ; Plot 5: VCO 2 and HR as a function of VO 2 ; Plot 6: Ventilatory equivalent for O 2 (VE/VO 2 ) and CO 2 (VE/VCO 2 ) versus time; Plot 7: Tidal volume (Vt) in liter versus VE (L/min); Plot 8: Respiratory exchange ratio (RER) versus time (minute); Plot 9: End-tidal pressure for O2 (PETO2) and CO2 (PETCO 2 ) and O2 pulse saturation % (SpO 2 ) versus time.
