The objective of this study is to evaluate the effect of hyperbaric oxygen therapy (HBOT) on
airway complications in post-lung transplant recipients with evidence of restricted levels of
blood and oxygen in the airway tissue. Study subjects with extensive airway tissue damage in
the early post-transplant period will be randomized to HBOT or usual care and followed
clinically for 12 months following randomization. The investigators hypothesize that HBOT
will decrease the number of airway complications in the treated subjects.
