Cardiopulmonary Exercise Testing (CPET) In Adults
Introduction[edit | edit source]
Cardiopulmonary exercise testing (CPET) is used to assess the integrative exercise responses involving the pulmonary, cardiovascular, haematopoietic, neuropsychological, and skeletal muscle systems.
It also used to evaluate.
- Exercise capacity, functional capacity and fitness
- Prognostic and Diagnostic evaluation of the patients with cardiovascular and pulmonary conditions e.g. ( Heart failure, Heart or Thoracic surgery, copd ) etc.
CPET involves the analysis of respiratory gases including.
- Respiratory oxygen uptake (Vo2),
- Carbon dioxide production (Vco2),
- Ventilatory measures during a symptom‐limited exercise test.
Technique[edit | edit source]
Cardiopulmonary exercise testing (CPET) can be assessed by Laboratory method (treadmill or bicycle ergometer)
Equipments[edit | edit source]
- Bicycle ergometer or Treadmill
- 12-ECG leads
- Non-invasive blood pressure cuffed monitoring
- A non‐re breathing valve is connected to a mouthpiece to measure VO2 and (VCO2) and also prevent mixing of inspired and expired air
- Pulse oximetry to monitor oxygen saturation levels.
Before attending the test[edit | edit source]
- Do not eat a heavy meal for 2 hours before
- Do not take alcohol for 4 hours before
- Do not take vigorous exercise for 30 minutes
- Do not wear any tight clothing that may restrict your breathing
- Do not smoke for at least 1 hour prior
