Sham remote ischemic preconditioning on the right arm is induced with a blood pressure cuff inflation at 20 mm Hg for 5 min and followed by a 5 min reperfusion at 0 mm Hg. The sham ischemia-reperfusion cycle is performed 3 times for a total of 30 min. This procedure is done after anesthetic induction, but before the patient is placed on cardiopulmonary bypass.

A 20 mm Hg blood pressure cuff on the right arm does not induce ischemia.

Remote ischemic preconditioning on the right arm is induced with a blood pressure cuff inflation at 200 mm Hg for 5 min and followed by a 5 min reperfusion at 0 mm Hg. The ischemia-reperfusion cycle is performed 3 times for a total of 30 min. This procedure is done after anesthetic induction, but before the patient is placed on cardiopulmonary bypass.

Cuff pressure for ischemia sham is 20 mm Hg, ischemia is 200 mm Hg and reperfusion is 0 mm Hg
