Pulmonary haemodynamic responses observed in brain dead and control animals during induction of BD and over 24 h. a Mean pulmonary arterial pressure peaked early after induction of brain death, increasing over the duration of the study. b Percent variance from baseline of mean pulmonary artery pressure demonstrates that this deviated to a greater degree over time than control animals. c Pulmonary vascular resistance index also demonstrated an early peak and had returned to levels consistent with controls by 24 h. Brain death was induced immediately after the baseline value at time 0
