Cardiopulmonary exercise test

Cardiopulmonary exercise test is a diagnostic method, which reflects the cardiopulmonary function index of the human body during the exercise of increasing load. Through comprehensive analysis of various parameters, we understand the interaction and storage capacity of the heart, lungs and circulatory system. Commonly used indicators: maximum oxygen uptake (maximaloxygen.uptake, VO2max), metabolic equivalent (metabolicequivalent, MET), oxygen equivalent (VE / Vo2), anaerobicthreshold (AT), exercise maximum ventilation (MVV), Cardiac output (CO), stroke volume (SV), oxygen consumption (O2 pulse), carbon dioxide output (Vco2), minutely ventilation (VE), Terminal tidal oxygen partial pressure (PETo2), terminal tidal CO2 partial pressure (PETco2), physiological dead space (Vd / Vt), dyspnea index (Dyspnea index), alveolar-arterial oxygen partial pressure difference (PA-aDO2) .
