Less than 2 hours
B) Less than 4 hours
C) Less than 6 hours
D) Less than 8 hours
E) There is no time limit (as far as organ is
Recommended optimal acceptable ischemic time between procurement
and re-implantation of donor lung to recipient body is up to 8 hours, though institutions may accept ischemic times
of up to 12 hours. Studies have shown that the risks of primary graft dysfunction and 30 day mortality increase with more
than 8 hours of ischemia.
