Times about the dramatic decrease in waiting times for patients on the lung-transplant waiting list, due in part by changes in allocation policies (from longest time on the list to a combination of medical need and ability to thrive after transplant). Technological advances have helped a lot, too, making it possible for more cadaveric lungs to be preserved for transplantation than ever before.
