Intra-individual coefficients of variation (CV) with the automatic elimination (AEA) and simultaneous visual inspection plus automatic elimination (SVI-AE) methods. Data are presented as median (interquartile range)
| BWBP parameters | Intra-individual CV of the AEA method (%) | Intra-individual CV of the SVI-AE method (%) |
|---|---|---|
| RR* | 24.9 (20.1–34.5) | 12.6 (9.7–15.2) |
| TV* | 24.7 (18.5–34.8) | 13.9 (10.8–15.4) |
| Penh* | 61.1 (43.5–89.9) | 34.7 (28.2–44.9) |

BWBP = barometric whole-body plethysmography; RR = respiratory rate; TV = tidal volume; Penh = enhanced pause, a unitless parameter ([peak expiratory flow/peak inspiratory flow] × pause)
