What is the recommended ratio of compressions to rescue breaths in CPR for adults?

The recommended ratio of compressions to rescue breaths in CPR for adults is 30 compressions to 2 breaths. This ratio is based on guidelines established by organizations such as the American Heart Association, and it is designed to provide effective support to someone experiencing cardiac arrest.

The rationale behind this specific ratio is to ensure that adequate blood flow is maintained through chest compressions while also providing enough oxygenation through rescue breaths. The 30:2 ratio allows for compressions to be delivered rapidly, which is essential to keep blood circulating to vital organs until emergency medical services can take over.

Additionally, this approach balances the need for ventilation with the importance of chest compressions. It emphasizes the critical nature of maintaining adequate circulation and oxygenation, particularly in a time-sensitive situation like cardiac arrest. Using this established ratio helps ensure consistency and effectiveness in CPR efforts, which can significantly increase the likelihood of survival for the victim.
