WebJul 10, 2024 · Pulmonary gas exchange parameters obtained during CPET appear to be superior to resting pulmonary function tests for the prognostication of ILD (Keogh and Crystal, 1980; Miller et al., 1995) and PaO 2 at peak exercise is a significant predictor of survival in IPF (King et al., 2001). The transport of oxygen to body tissues depends largely on cardiac output, haemoglobin (Hb) concentration, Hb oxygen saturation, arterial vascular tone and the density of the capillary network. A basic working knowledge of exercise (patho)physiology and gas exchange is fundamental to … See more The ratio of ventilation (V) to perfusion (Q) is decisive for the quality of the gas exchange in the lungs. Pronounced ventilation/perfusion mismatch (V/Q) occurs in pulmonary disease, pulmonary vascular disorders … See more Incremental exercise should ideally last for 10 ± 2 min, or for at least 5 min in severely restricted patients. The selection of a work rate increment that is too rapid (ramp too steep) should be avoided because this is often associated with … See more CPET is typically performed using a cycle ergometer or treadmill [1, 3, 5, 11].
