Description of intervention(s) / exposure
Normal best standard practice with remote ischaemic post-conditioning using 3 cycles of transient leg ischaemia and reperfusion (5 min ischaemia followed by 5 min reperfusion, 3 times) using a thigh tourniquet at least 5 min prior to donor lung reperfusion. Total stimulus 30 minutes prior to reperfusion.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be approached in an outpatient setting and written informed consent will be obtained. Eligible patients undergoing lung transplantation will be randomised using a computer-generated list and sealed opaque envelopes. Surgical and nursing staff will be blinded to the treatment groups as tourniquets will be applied to all patients but not inflated in controls.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will occur using a computer-generated list and sealed opaque envelopes.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
