Cаleb recоvers well enоugh tо be dischаrged from the hospitаl. He also begins to undergo additional testing for lung transplantation eligibility. After assessment by the lung transplant team, he is placed on the transplant waiting list with a lung allocation scale of 68. He is unable to continue participating in PR due to his deteriorating condition and begins using supplemental oxygen at home. He also moves into an apartment with his mother, which is closer to the lung transplant center. After 5 months on the wait list, Caleb receives a double lung transplant from an adult male cadaver donor. Following a 14-hour surgery, he is transferred to ICU, place on mechanical ventilation. On day 2 post-op he is weaned from mechanical ventilation and displays no complications or signs of acute organ rejection. On day 4 he is transferred from ICU to a hospital ward. On day 15 he is discharged to his local apartment. Immediately following the procedure, he is placed on immunosuppressant regime including prednisone, tacrolimus, and mycophenolate mofetil. For the first 3 months post-transplant he is followed by the transplant team for weekly medical checkups and attends a pulmonary rehab program 2-3x a week.
