What is the recommended compression-to-breath ratio for adults when administering CPR?

The recommended compression-to-breath ratio for adults when administering CPR is 30:2. This means that for every 30 chest compressions administered, the rescuer should provide 2 rescue breaths. This ratio has been established based on studies that evaluate the effectiveness of CPR in increasing survival rates in cardiac arrest situations.

The emphasis on a higher number of compressions (30) in relation to breaths (2) aims to maximize blood flow to vital organs and ensure that oxygen continues to circulate throughout the body during a critical situation. Chest compressions are incredibly important because they maintain oxygen delivery to the heart and brain, which are vital for survival. The 30:2 ratio allows for a more continuous and effective administration of compressions, which is crucial in improving outcomes during resuscitation attempts.

In contrast, other ratios like 15:2, 30:5, or 1:1 do not align with current guidelines, as they either reduce the number of compressions or create an imbalance that may hinder effective blood circulation during CPR. This is why the 30:2 ratio is the standard recommendation for adult CPR.
