Ventilatory gas analysis during cardiopulmonary exercise testing provides a practical method to simultaneously investigate cardiopulmonary and metabolic changes and identify causes of exercise intolerance.
Assessing ventilatory gas exchange during exercise is a crucial component of cardiopulmonary exercise testing (CPET). Fatigue or breathlessness during physical exertion can arise from diverse underlying conditions and may not strongly correlate with resting functional or imaging tests. Examining ventilatory gas exchange during exercise provides a chance to investigate both cardiopulmonary and metabolic changes simultaneously. CPET aids in distinguishing between a normal and abnormal exercise response, often identifying the underlying cause of exercise intolerance among various potential pathophysiological conditions. However, comprehending ventilatory gas exchange during exercise necessitates specific expertise, and there remains a substantial knowledge gap for physicians interested in thoroughly understanding the systematic analysis and interpretation. This article outlines the fundamental principles of exercise physiology and provides a practical guide to interpreting the results of ventilatory gas analysis during CPET.
Sora Baek (Fri,) conducted a review in Exercise intolerance. Cardiopulmonary exercise testing (CPET) with ventilatory gas analysis was evaluated. Ventilatory gas analysis during cardiopulmonary exercise testing provides a practical method to simultaneously investigate cardiopulmonary and metabolic changes and identify causes of exercise intolerance.
