Cardiopulmonary Exercise Testing (CPET) is the most comprehensive examination for assessing exercise endurance and cardiorespiratory function in children during physical activity.
What is CPET:
It is a test performed on a treadmill or cycle ergometer, with simultaneous recording of:
- oxygen consumption (VO₂)
- CO₂ production
- heart rate
- respiratory function.
When is it needed:
- exercise-related dyspnea
- reduced endurance
- asthma or chronic lung disease
- differential diagnosis of cardiac vs. respiratory causes.
Why is it important:
It helps accurately identify the cause of exercise intolerance and design an individualized exercise plan.
