Fig 1 Schematic overview of the experimental groups starting at death of the animals. (E = evaluation; h = hours; HBD = heart-beating donor; min = minutes; NHBD-TC3 = nonheart-beating donor plus 3 hours topical cooling; NHBD-TC6 = nonheart-beating donor plus 6 hours topical cooling.)

Fig 2 (A) Technique of topical cooling. One inflow drain and one outflow drain was inserted in each pleural cavity. (B) The two outflow drains were connected to a 5 cm H2O overflow system. The Annals of Thoracic Surgery 2004 77, 438-444DOI: (10.1016/S0003-4975(03)01343-2)
Fig 3 Endobronchial temperature decline after death in the two study groups: nonheart-beating donor plus 3 hours topical cooling (NHBD-TC3, dotted line) and nonheart-beating donor plus 6 hours topical cooling (NHBD-TC6, solid gray line).

(HBD = heart-beating donor; Min-Max = minimum-maximum; NHBD-TC3 = nonheart-beating donor plus 3 hours topical cooling; NHBD-TC6 = nonheart-beating donor plus 6 hours topical cooling.)
