- The document discusses principles for managing multi-organ donors to optimize organ preservation for transplantation. It emphasizes cardiovascular and pulmonary management to minimize donor organ injury. - The SALT protocol increased lung donors and transplants by improving donor lung recruitment and classification. It showed donor lungs previously deemed "poor" could be used if given recruitment maneuvers. - New approaches like ex vivo lung perfusion now allow for evaluating and potentially repairing marginal donor lungs before transplantation instead of immediate decline. This may help increase the utilization and outcomes of donor lungs.
