Functional data during successful EVLP are presented, comparing data over time (one-way anova; P < 0.05). Average data measured during the Reperfusion phase were significantly different from data measured during Reconditioning and Evaluation (see Supporting Information). Data are presented as mean ± standard deviation. In the upper part of the table, set parameters are presented, whereas derived parameters are presented in the lower part of the table. LA Temp, left atrium temperature (°C); Vt, tidal volume (ml/kg donor ideal weight); PAPm, mean pulmonary arterial pressure (mmHg); PVR, pulmonary vascular resistance (dyne*s/cm5); Pawm, mean airways pressure (cmH2O); Pawpeak, peak airways pressure (cmH2O); Cpldyn, dynamic lung compliance (ml/cmH2O). PO2 IN, partial pressure of oxygen from a sample of perfusate taken from the pulmonary artery cannula (mmHg); PO2 OUT, partial oxygen pressure from a sample taken from the left atrium (mmHg).
