What is the correct ratio of chest compressions to breaths in CPR?

In cardiopulmonary resuscitation (CPR), the correct ratio of chest compressions to breaths for adults and children is 30 compressions for every 2 breaths. This ratio is vital for providing effective assistance during a cardiac arrest or without a pulse, as continuous chest compressions help maintain blood flow to the heart and brain. The 30:2 ratio allows for an efficient mix of compressions and ventilations, ensuring that the patient receives both circulatory support and oxygenation.

These guidelines are set by organizations like the American Heart Association and are based on research to determine the most effective approach to cardiopulmonary resuscitation. Maintaining a high quality of chest compressions while minimizing interruptions for breaths maximizes the chances of survival for the patient, making the 30:2 ratio standard protocol in CPR training.
