FIELD: medicine.
SUBSTANCE: invention refers to medicine, namely to cardiosurgery, and can be used in on-pump cardiac surgeries. They are ensured by activation of ischemic preconditioning as follows. After the termination of artificial pulmonary ventilation and the beginning of parallel complete by-pass, before clipping the aorta, two cycles are performed: the 3-minute hypoxemia by supplying the mixed gas with oxygen concentration decreased to 21-22 % to an oxygenator that is followed with the 2-minute reoxygenation.
EFFECT: method allows providing adequate vital protection without injuring the atherosclerotic aorta.
