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

In adult CPR, the appropriate compression to ventilation ratio is 30:2. This means that for every 30 chest compressions given, 2 rescue breaths should be administered. This ratio is widely recommended by organizations like the American Heart Association because it optimizes the chances of survival and successful resuscitation.

The emphasis on delivering 30 compressions before giving 2 breaths helps maintain adequate blood circulation to vital organs while ensuring that oxygen is delivered to the lungs. The ratio effectively strikes a balance between maintaining blood flow and providing oxygenation, which is critical in an emergency scenario where the patient is in cardiac arrest.

In contrast, other ratios, like 15:2, were applicable in some previous guidelines but have been adjusted in recent protocols to improve outcomes. The 20:1 and 5:1 ratios are not recognized as standard practices and could result in inadequate oxygen delivery or ineffective circulation if used during adult CPR. This systematic approach is essential for anyone performing CPR, whether trained or bystander responders, as it is vital to follow the prescribed protocols to enhance the chances of survival in cardiac emergencies.
