3rd Step: Look, Listen, And Feel. (LLF)
In this step you are looking for
chest movements, listening for breaths and feeling to see if any air is
coming out of their mouth or nose. You will want to do this for about 10
seconds.
4th Step: Ventilate 
If they are not breathing, then
you must give them 2 quick breaths. Pinch the victims nose with one hand
and cover their mouth with yours and blow until you see the chest rise.
Do this twice.
