Hyperbaric Oxygen Therapy for Lung Transplantation

2 hours of breathing \>99% medical grade oxygen inside an air-pressurized chamber at 2 ATA once a day for 20 sessions. These sessions will be scheduled 3-5 times per week, depending on the availability of the patient and the hyperbaric medicine physician.

During standard post-transplantation bronchoscopies, participants in this study will undergo an endobronchial biopsy of the airway epithelium for each donor lung.
