Please choose the correct solution to the question: What is the current standard way for a bystander to provide CPR?

Solution1: Earlier methods included alternating chest compressions and mouth to mouth breathing for an unconscious victim, where where the person had stopped breathing. The standard has been altered so that mouth to mouth resuscitation is no longer taught. Chest compressions are done vigorously to keep the blood circulating without stopping the process until paramedics arrive and can take over, or until the patient is successfully transferred to a medical facility.

Solution2: Earlier methods included alternating chest compressions and mouth to mouth breathing for the unconscious victim. Today the procedure has been simplified where vigorous breathing is continued until the paramedics arrive or until the patient has been successfully transferred to a medical facility and others can take over.
