When performing cpr on an unresponsive choking victim, what should you do?

When performing Cardiopulmonary resuscitation is an emergency procedure which combines chest compression often with artificial ventilation.

This is required in the condition where there is a requirement of artificial breathing because the victim is not able to breathe naturally on its own.

In case the person is choking, compression must be carried out for 30 minutes continuously and then CPR should be given until medical help arrives.
