What is the proper compression to ventilation ratio for CPR on any individual?

The proper compression to ventilation ratio for CPR on an individual is 30:2. This means that for every 30 chest compressions given, there should be 2 rescue breaths administered. This ratio is recommended for adults and children, ensuring that sufficient blood circulation is maintained through compressions while also providing necessary oxygenation through ventilation.

The 30:2 ratio is particularly important because it signifies the most effective balance between the two lifesaving techniques—compressions and ventilations—during a cardiac arrest situation. Chest compressions are crucial because they help circulate blood to vital organs, while rescue breaths provide oxygen to the lungs. The emphasis on 30 compressions followed by 2 breaths optimizes the chances of survival by effectively maintaining both blood flow and oxygen supply.

In contrast, other ratios presented, such as 15:2, 20:2, and 10:1, do not align with the current guidelines established by organizations such as the American Heart Association, which recommends 30:2 to maximize the effectiveness of CPR in emergencies.
