Final answer:

The correct CPR compression-to-ventilation ratio for an adult is 30:2, with 30 chest compressions followed by 2 rescue breaths, and chest compressions should be at least 5 cm deep at a rate of 100 per minute.

Step-by-step explanation:

The correct compression-to-ventilation ratio for adult CPR according to current standards is 30:2. This means that you should give 30 chest compressions followed by 2 rescue breaths. When performing CPR, compress the chest at least 5 cm deep and at a rate of 100 compressions per minute. The beat of "Staying Alive" by the Bee Gees is used to help remember this rate. It's essential to continue CPR until trained healthcare professionals take over or until the patient regains spontaneous contraction. These high-quality chest compressions are more important than providing artificial respiration, as they help to maintain blood flow especially to the brain, preventing irreversible damage.
