What is the recommended compression to breath ratio in CPR?

The recommended compression to breath ratio in CPR for adults is 30:2. This means that after performing 30 chest compressions, you should give 2 rescue breaths. This ratio is emphasized in guidelines because it allows for optimal oxygenation and blood circulation while minimizing interruptions in chest compressions, which are critical for maintaining blood flow to vital organs during a cardiac arrest.

In practical terms, performing 30 compressions followed by 2 breaths helps respond effectively to the physiological needs of a person experiencing cardiac arrest. This method aims to maximize the effectiveness of CPR by ensuring a continuous flow of blood while also providing the necessary ventilation through rescue breaths.

This CPR ratio is designed for one-rescuer scenarios. In cases where there are two rescuers, a compression to breath ratio of 15:2 may be used for pediatric patients, but in adult CPR situations where a single rescuer is performing the procedure, the 30:2 ratio is standard. Understanding this ratio is fundamental in delivering effective life support and improving outcomes in emergency situations.
