Question

When performing CPR, why is the exact depth and speed of your chest pushes so important for getting oxygen to the brain?

Accepted Answer

When someone&#x27;s heart stops, it can no longer pump blood to the brain. Your chest pushes act as a manual pump to take over this job. If you push too shallow, you won&#x27;t squeeze the heart hard enough to move the blood out. Think of it like trying to get water out of a half-full sponge; if you don&#x27;t squeeze it all the way down, the water stays inside. If you push too deep, you might hurt the chest, but if you don&#x27;t push deep enough, the blood just stays still. The speed of your pushes matters just as much. You need to push at least 100 times every minute to keep a steady flow going. If you go too slow, the blood doesn&#x27;t move fast enough to reach the brain. If you go too fast, the heart doesn&#x27;t have enough time to refill with blood between pushes. It is like a pump that needs to fully fill up with water before it can push that water through a hose. By getting the depth and speed just right, you keep fresh, oxygen-rich blood traveling to the brain so it can stay alive until professional help arrives.
