What is the compression ratio for adult CPR?

The correct compression ratio for adult CPR is 30 compressions to 2 breaths. This ratio is a part of the latest guidelines provided by the American Heart Association (AHA) for performing high-quality cardiopulmonary resuscitation (CPR).

The ratio of 30:2 is recommended for both lay rescuers and healthcare providers during adult resuscitation efforts. This means that after performing 30 chest compressions at a rate of 100 to 120 compressions per minute, the rescuer should provide 2 effective rescue breaths. This approach is designed to maximize blood flow to the heart and brain while ensuring adequate oxygenation, which is critical in improving the chances of a successful resuscitation.

Using this specific compression-to-breath ratio helps maintain a rhythmic and efficient cycle of compressions and ventilations, ensuring the victim receives the necessary lifesaving interventions during cardiac arrest.
