Here we can see the CPR cycle. It consists on first checking out if the pacient is conscious or not. We will check it by his/her senses and depending on how his body responds. In case the person does not breath we either should ask for help or apply the Cpr. It will consist on 30 chest compresions and 2 rescue breaths. In case of being a baby, such as the one in the video, before we will have to do 5 insuflations, covering the baby's mouth ans nose.
