Dynamic changes in select cardiopulmonary metrics during cardiopulmonary exercise testing (CPET) with BVF and without (true value) a BVF. (a) specialist BVF; (b) provides the correction required when conducting CPET with a BVF. Modified Bland‐Altman plots display the mean difference between BVF and true values for: (c) Pulmonary ventilation (V˙E), +10.2 l.min‐1 (p < 0.001) and (d) Oxygen uptake (V˙O2), +5.6 ml.min‐1.kg‐1 (p < 0.001). Data points represent the middle five of seven breaths subsequently averaged for each 10 W increment of power output. Reference ranges are from patients (n = 3168) who underwent CPET before major surgery; mean (SD) V˙E 49.8 (17.9) l.min‐1 and V˙O2peak 16.1 (5.0) mlO2.min‐1.kg‐1.
