During CPR, how many times should the compression and breath cycle be repeated?

The correct answer reflects the established guidelines for CPR (cardiopulmonary resuscitation) provided by organizations such as the American Heart Association. According to these guidelines, while giving CPR to an adult, the cycle for compressions and breaths typically consists of 30 compressions followed by 2 rescue breaths. This full compression and breath sequence should continue until help arrives or the individual begins to show signs of life.

Repeating this sequence approximately five times allows for an effective and sustained effort in providing assistance, ensuring that oxygen is delivered and circulation is maintained as much as possible during a critical situation. This frequency strikes a balance between delivering adequate compressions to maintain blood flow and providing breaths to oxygenate the blood.
