Oto et al developed a simple score for evaluating the lungs from a donor. The authors are from Alfred Hospital and Monash University in Melbourne, Australia.
Parameters:
(1) age of the donor in years
(2) pack years of smoking
(3) chest X-ray
(4) secretions
(5) ratio of PaO2 to FIO2

lung donor score =
= SUM(points for all 5 parameters)
Interpretation:
• minimum score: 0
• maximum score: 15
• The lower the score the better the lungs.
