 The biggest difference is that it's better because it replenishes the oxygen deprivation that the organs incur during the dying process. And what's the advantage of that? Well, if we recover the organ and put it on ice in an oxygen-deprived state, it's not as healthy when it gets into the recipient. And this way, it's actually recovered in a healthier state, so that when it does get to the recipient, it's more likely to work.
