The interpretation of Cardiopulmonary Exercise Testing (CPET) involves analysing various physiological parameters to assess a patient’s exercise capacity and identify factors that may be limiting it. Key parameters include  five primary measurements—oxygen uptake, heart rate, ventilation, carbon dioxide output, and peripheral oxygen saturation (SpO2);  three derived indices—oxygen (O2) pulse, the respiratory exchange ratio, and ventilatory equivalents; as well as  the anaerobic threshold (AT)
