It's the most important part of CPR- this action ensures that you pump blood to the brain and heart. Chest recoil allows blood to flow into the heart and is necessary for chest compression to create blood flow. Any break in pumping means you are not getting blood to your body. Excessive ventilation during is likely to increase intrathoracic pressure, decrease venous return to the heart, and diminish CO.
