CPET cardiopulmonary exercise testing
Cards in this deck (6)
- 1Peak VO2Highest oxygen uptake obtained (aerobic capacity)
Peak VO2 >85% of predicted is generally facorable - 2Ventilatory Threshold (VT)Point at which anaerobic metabolism increases VO2 at ventilatory threshold typically is 40-60% of peak VO2
Highest VO2 that can be achieved without developing lactic acidosis (indication that anaerobic metabolism is predominating) - 3VE/VCO2 slopeVentilatory volume/carbon dioxide output
Reflects ventilatory efficiency
Normal 25-30
Elevated values reflects ventilatory inefficiency or ventilation-perfusion mismatch - 4O2 pulseoxygen delivered per heart beat
a surrogate for stroke volume - 5Ventilatory reserve (breathing reserve)Peak exercise ventilations (VE) divided by predicted or measured maximum voluntary ventilation (Mvv)
Normal: 15%-20%
Maybe reduced or absent in elite athletes
Reduced reserve suggests pulmonary limitation - 6Respiratory exchange Ration (RER)Peak respiratory exchange ration
(VCO2/VO2)
Normal <0.8 at rest
increase during exercise
