Incredibly rare to get decent lungs and incredibly intensive on the body (and wallet) and the outcomes are often awful and amount to a disturbingly draw-out death. Many live, but the lifestyle isn’t worth really it. These people live for maybe 10-15 more years if they don’t die in the ICU in the first few months (or before they get a transplant).
Or die from infection soon after because their immune system is suppressed. They also tend to have insane anxiety and PTSD from the entire process. It’s basically a meme in the medical community about how awful transplant patients are to take care of because they’re essentially inconsolable about nearly everything due to the absurd amount of mental/physiological anguish they experience after months in the ICU.
