Table 1.
Grading of primary graft dysfunction (PGD) after lung transplantation (LTx) according to the 2016 definition of the International Society for Heart and Lung Transplantation (ISHLT).
| Grade | Bilateral Alveolar Infiltrates on Chest X-ray | PaO2/FiO2 Ratio |
|---|---|---|
| PGD grade 0 | No | Any |
| PGD grade 1 | Yes | >300 |
| PGD grade 2 | Yes | 200–300 |
| PGD grade 3 | Yes | <200 |
PGD is graded at 4 time-points over the first 72 h after LTx, i.e., every 24 h starting at reperfusion of the second lung (T0, T24, T48 and T72) [1]. FiO2 = fraction of inspired oxygen; PaO2 = partial pressure of arterial oxygen; PGD = primary graft dysfunction.
