Impact of Hyperoxia During Cardiopulmonary

Impact of Hyperoxia During Cardiopulmonary Bypass in the Occurrence of Cardiovascular Complications After Cardiac Surgery

The hypothesis implies that this work is the use of hyperoxia during cardiopulmonary bypass by his heart preconditioning effect is associated with a lower incidence of cardiac arrhythmias (atrial fibrillation, tachycardia or ventricular fibrillation) and lesions of myocardial ischemia-reperfusion injury in cardiac surgery postoperative.
