In adult CPR, what is the correct ratio of compressions to breaths?

The correct ratio of compressions to breaths in adult CPR is 30 compressions to 2 breaths. This ratio is part of the guidelines established by organizations like the American Heart Association, which aim to optimize the chances of survival in a cardiac arrest situation.

This compression-to-breath ratio is designed to maximize the efficiency of CPR. The emphasis on performing 30 compressions allows for a higher frequency of blood circulation due to chest compressions, which is crucial for maintaining blood flow to vital organs. The two rescue breaths that follow help provide oxygen to someone who is not breathing, supporting their oxygenation until further medical help arrives or the person resumes normal breathing.

The guidelines stipulate this particular ratio for adult victims, as it creates a balance between maintaining blood circulation and providing oxygen, thus improving the likelihood of a successful outcome in a resuscitation scenario.
