Evidence shows that LVCC during TCPA improve hemodynamics and ROSC compared to standard CC. REBOA improves hemo-dynamics and controls hemorrhage during TCPA. Hypothesis REBOA and LVCC improve hemodynamics and ROSC in swine. TTE used to mark the AR and LV on animals n52 which were randomized to CC in one of two areas. Half the animals in each group had REBOA 30 hemorrhage and VF induced to simulate TCA. After 10 min of VF, BLS initiated for 10 mins, ACLS wblood transfusion for 10 more mins. REBOA balloon inflated at BLS min6. ROSC increased in standard CC wREBOA33 compared to standard CC wout REBOA0.0p0.04. In standard CC animals, aortic SBP, right atrial SBP and ETCO2 increased during BLS p0.005 wREBOA. ETCO2 increased during BLS in LVCC wREBOA compared to LVCC wout REBOAp0.0001. ROSC and other hemodynamics no significant difference. No difference in ROSC or hemodynamics between the LVCC and standard CC wREBOA. In our model of TCPA, ROSC and hemodynamics improved in standard CC arm. No additional benefit with REBOA in LVCC.
