How many breaths and compressions are performed for each cycle of CPR?

In the context of CPR, the recommended ratio for adult and pediatric victims, who are not newborns, is to perform 30 compressions followed by 2 breaths. This combination is based on guidelines established by organizations such as the American Heart Association.

The rationale behind this approach is that it optimizes blood circulation during compressions while also ensuring the victim receives sufficient ventilation to increase oxygenation. The focus on 30 compressions allows for a consistent and effective rhythm to maintain blood flow to vital organs. The 2 breaths are then provided to help restore oxygen levels, crucial in a cardiac arrest situation where the heart is not pumping blood effectively.

This structured method is designed to be repeated until emergency medical services arrive or the person starts showing signs of life. Understanding this cycle is essential for effective CPR, leading to better outcomes in resuscitation efforts.
