Performing CPR does two very important things. First, compressions move oxygen-rich blood to the brain, helping keep it alive. Second, they send blood and oxygen to the heart muscle, giving the heart the best chance to return to a normal rhythm after an AED shock. When you begin compressions, you create an artificial pump and manually do the heart's job. Every effective compression builds pressure, pushing blood through the heart and toward the brain. Because this pressure takes time to build, you need to push hard and fast. Place your hands in the center of the chest and push down at least two inches and give 100 to 120 compressions per minute. If you stop compressions, blood flow to the brain also stops, so keep interruptions as short as possible when giving breaths or switching roles. This is what happens if you do not push deeply or quickly enough. Enough blood may not reach the brain. On the other hand, pushing too fast does not give the hard enough time to refill. Remember, push hard, push fast, and allow the chest to fully recoil.
