Abstract:
The cardiopulmonary exercise test (CPX) is an essential examination for detecting pathophysiological derangement and determining treatment policy because it clarifies not only the changes of hemodynamics but also abnormality in the whole body during exercise where heart disease patients often feel symptoms.To utilize CPX effectively, we must understand each parameter, such as peak oxygen uptake (peak VO2), peak VO2/HR, and VE/VCO2. In addition, comparison of each parameter, for example, peak VO2 and VE/VCO2, and peak VO2 and peak VO2/HR, is useful to detect the pathophysiological abnormalities.In this article, I will describe how CPX should be used in clinical settings.

Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
Purposes
Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
