Table 2 Normal cardiopulmonary exercise testing variables
VariablesNormal value
Peak oxygen content (PVo2)>84 Predicted
Ventilatory anaerobic threshold (VAT)>40 PVo2 (4080)
Maximum heart rate (HRmax)>90 Age predicted
Heart rate reserve (HRR)<15 Beats/min
Blood pressure (BP)<220/90
O2 pulse (Vo2/HR)>80
Ventilatory reserve (VR)MVVVEmax >11 litres or VEmax/MVV 100 <85
Respiratory rate (RR)<60 Breaths/min
Minute ventilation/carbon dioxide output ratio (VE/Vco2) at VAT <34
  • MVV, maximal voluntary ventilation; VE, expired ventilation.
