Which song do we use to describe the optimal rhythm while performing CPR?

The right answer is C- Stayin' alive- Bee Gees. This song is perfect to keep the rhythm of the chest compressions while performing CPR because it is about 100 beats per minute. Obviously, we don’t want to be too slow but going too fast is also a problem because we don’t give the heart enough time to get filled with blood. The less blood we have inside the heart before we compress the chest the less blood we are going to pump out of it and consequently the less blood will reach the brain. This is why we need an optimal rhythm of 100 steady beats per minute.
