Correlated Variability in the Breathing Pattern and End-Expiratory Lung Volumes in Conscious Humans
Fig 5
a) Bland-Altman analysis for the repeatability of the chest wall end-expiratory (EEVcw, upper panel) and tidal (VT,cw, lower panel) volumes long term correlations.
Each data point represent the value of α measured in the same subject during two different experimental session with from 3 to 9 month time interval between the measurements. b) α values as a function of the number of breaths considered for the analysis for total and compartmental end-expiratory chest wall volumes.
