What is the recommended CPR compression to breath ratio for adults?

15 compressions for every 2 breaths
30 compressions for every 2 breaths
30 compressions for every 1 breath
20 compressions for every 2 breaths

The correct answer is: 30 compressions for every 2 breaths

The recommended compression to breath ratio for adults during CPR is 30 compressions for every 2 breaths. This ratio is based on guidelines provided by leading health organizations, including the American Heart Association. The primary goal of CPR is to maintain blood flow to vital organs, particularly the heart and brain, during a cardiac arrest. The 30:2 ratio is intended to optimize blood circulation through chest compressions while also providing effective ventilation. The compression rate of 30 compressions per minute is ideal as it allows for a higher number of compressions to be delivered, which is crucial for maintaining adequate blood flow. Following each set of 30 compressions, administering 2 rescue breaths ensures that the victim receives oxygen, which is essential for preserving brain function until emergency medical services arrive. This ratio has been widely adopted because it balances the need for continuous compressions— which help sustain perfusion—with the need to provide ventilation. Other ratios, such as 15:2 or 20:2, are not recommended in standard adult CPR guidelines, as they may disrupt the quality and frequency of chest compressions needed to effectively support circulation in a cardiac emergency.
