Answer:
Put the person on his/her side to let out some throw up
Explanation:
It should be understood that  the meaning of CPR is cardiopulmonary resuscitation. And it is an emergency life-saving procedure that is done when someone's breathing or heartbeat has stopped.
The stoppage of the breathing may have happened after an electric shock, heart attack, or drowning.
In this case, the person can be laid on his/her side to let out some thrown up, which will through the air passage and subsequently allow breathing.
It should be noted that, only CPR has been shown to be effective.
