Cardiopulmonary exercise testing (CPET) is an advanced tool used to evaluate the efficiency and interaction of the heart, lungs, and muscles during exercise. Here’s a concise summary suitable for a medical website:


CPET assesses how well the body uses oxygen and eliminates carbon dioxide, providing a comprehensive evaluation of cardiovascular and pulmonary responses to physical stress.


The test usually involves exercising on a treadmill or stationary bike while connected to equipment that monitors breathing, oxygen usage, carbon dioxide output, and heart activity.

Key Measurements:

  • Oxygen consumption (VO2 max)
  • Carbon dioxide production
  • Heart rate and rhythm
  • Breathing patterns and lung function


  • Diagnosing unexplained exercise intolerance
  • Investigating symptoms such as shortness of breath and fatigue
  • Assessing the severity and impact of cardiovascular and pulmonary conditions
  • Evaluating fitness levels for major surgery and tailor exercise and rehabilitation programs


  • Provides detailed, objective data that helps in accurate diagnosis and management
  • Helps in formulating personalized treatment and conditioning plans
  • Useful in both clinical settings and athletic performance optimization

CPET is invaluable for healthcare professionals to better understand and manage a variety of health conditions, enhancing both patient care and exercise planning.
