Fig 1 General correlation between the number of pulmonary veins with partial pressure of oxygen (Po2) less than 300 mm Hg in the donor and the incidence of primary graft dysfunction (PGD; p = 0.01). Only pulmonary vein gases of transplanted lungs were included in the analysis.

Fig 2 Correlation between the number of pulmonary veins with partial pressure of oxygen (Po2) less than 300 mm Hg in the donor and the incidence of primary graft dysfunction (PGD). Separate analysis of single and bilateral lung transplants. Only pulmonary vein gases of transplanted lungs were included in the analysis. (□ = single; ■ = bilateral.)

Fig 3 Scatter plot demonstrating the poor correlation between arterial partial pressure of oxygen to fraction of inspired oxygen Po2/Fio2 ratio at referral and the lowest pulmonary vein gas (PVG) Po2/Fio2 ratio in each transplanted lung.

Fig 4 Scatter plot demonstrating the correlation between the lowest pulmonary vein gas (PVG) Po2/Fio2 ratio and the Po2/Fio2 ratio in the ipsilateral pulmonary vein. Best-fit linear regression with 95% confidence interval. (y = x; Po2/Fio2 = partial pressure of oxygen to fraction of inspired oxygen.)
