What is the correct compression to ventilation ratio for adult CPR?

The correct compression to ventilation ratio for adult CPR is 30 compressions to 2 ventilations. This approach is recommended by organizations such as the American Heart Association and is based on extensive research into the most effective methods for maintaining blood flow and providing oxygen to a patient in cardiac arrest.

During CPR, the primary goal is to ensure consistent and effective chest compressions that maintain blood circulation to vital organs. The 30:2 ratio is designed to maximize the number of compressions while still allowing for the administration of rescue breaths. This balance is crucial because high-quality compressions are essential for preserving brain function and increasing the chances of survival. The ratio emphasizes the importance of rapid compressions with periodic ventilations to restore oxygen levels in the body.

Higher compression rates without sufficient ventilations could jeopardize the effectiveness of rescue efforts, which is why this specific ratio is the standard for adult patients. Understanding this ratio is fundamental for anyone performing CPR, as it directly impacts outcomes for individuals experiencing cardiac arrest.
