The Good Samaritan

Any persons who assist those who are injured, ill or in peril are protected by the Good Samaritan Law. As long as they’re acting voluntary, without expectation of reimbursement or compensation while performing such aid, on site—they’ll have legal protection.

It's important to note: that the AHA guidelines recommends in-confident performers of CPR should, at least, perform chest compressions upon the patient, since studies show chest compressions can be as effective as the combination of CPR.
