Bedside techniques to quantify dynamic pulmonary hyperinflation compared with the gold standard (Veireference). Fairly good correlations were found between Veireference and Veimaneuver (A) and between Veireference and Veiformula (B). Bland–Altman analysis showed low bias and wide limits of agreement between Veireference and Veimaneuver (C) and between Veireference and Veiformula (D). Furthermore, there is a relationship in the bias between Veireference and Veiformula (solid line with dashed 95% CI lines)
