Figure 5: Stabilization Perfusion Ischemia Reperfusion Administration of 200 μg of omeprazole antegrade. Algorithm of different groups studied IControl; II- Ischemia; III- Ischemia + 200 μg of omeprazole; IV- Preconditioning; V- Preconditioning + 200 μg of omeprazole. t0=First collect the corresponding hemodynamic variables after the stabilization period. The times t15’t30’ and represent the collection times of the variables of each group.
