Why is adequate depth during chest compressions during CPR important?

Answer 1

The aim of chest compressions is to squash the heart under the chest.

Every compression 'squashes' the heart, this causes all of the blood to be pumped out of the heart and off round the body, taking the oxygen with it (assuming you're doing the breaths as well). You then come back up, allowing the heart to refill before you compress again.

In this way you are reproducing a heartbeat for someone who doesn't have one.

Answer 2

Chest compressions are the part of CPR technique meant to pump bloor through the body even if the heart has stopped. The valves in the heart allows the heart to keep pumping when it's stopped if it's squeezed. So to squeeze the heart you push down quite firmly in the center of the chest and that's called chest compressions.

Answer 3

weather the chest goes up or not is not important the person is not breathing there for there chest wont move up as normal a helpful tip is to to the compressions to the beat of we will rock u just the part where they sing "we will we will rock you"

Answer 4

If the chest does not recoil, it will not fill with blood.

Answer 5

It is important because you want to get the heart going and blood flowing through the heart and body.
