Single-Lung Transplant Results in Position Dependent Changes in Regional Ventilation: An Observational Case Series Using Electrical Impedance Tomography

Table 4

Results for tidal variation (%) by position. Negative results mean a greater reading in the transplanted lung. Tidal variation of impedance measures only a cross section of the chest wall and correlates well with tidal volume.

Position	Mean difference (diseased versus transplanted lung) [in AU]	95% confidence interval	value
Lying on back	−29	−74, 17	0.32
Lying on left side	−21	−66, 24	0.45
Lying on right side	−29	−74, 16	0.30
Sitting up in bed	−26	−71, 19	0.37
Standing	−30	−75, 16	0.30
