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

The standard compression-to-ventilation ratio for CPR (Cardiopulmonary Resuscitation) in adults is 30:2. This means that for every 30 chest compressions delivered, 2 rescue breaths are administered. This ratio is crucial for ensuring both the circulation of oxygenated blood to vital organs and the delivery of oxygen to the lungs.

During CPR, effective chest compressions are the priority, as they help maintain blood flow to the heart and brain until advanced medical help arrives. The combination of compressions and ventilations is designed to balance the need for blood flow with necessary oxygenation.

The 30:2 ratio is particularly focused on adult victims; for infants and children, the ratio might differ if there are two rescuers involved, highlighting the significance of adjusting techniques based on the age and circumstances of the patient. Understanding this ratio is essential for anyone performing CPR, ensuring that the rescue efforts provide the best chance of recovery for an individual in cardiac arrest.
