Are you paying attention, everyone?

Applying pressure to the chest area is a vital part of performing CPR.

It should be done 100 to 120 times per minute.

No hesitation. Push as if you were trying to break a rib.

HAH!!

I might have applied a bit too much strength.

Oh well, these things happen...

Sensei, I will do another demonstration. Please lay down on your back.
