What is the proper procedure when administering CPR?

The proper procedure for administering CPR involves performing 30 chest compressions followed by 2 rescue breaths for adults and children. This approach is established in CPR guidelines to ensure that an adequate flow of blood is maintained to the heart and brain during a cardiac emergency. The 30:2 ratio is effective as it allows for a significant number of compressions to keep blood circulating, while the rescue breaths provide oxygen to the lungs, important for sustaining life until advanced medical help arrives.

The emphasis on performing 30 compressions before providing breaths ensures that the heart is being mechanically assisted in its function to pump blood, crucial during cardiac arrest situations. This method balances the need for effective circulation with the critical need for oxygenation. By adhering to this ratio, CPR is performed in a manner that aligns with current best practices for emergency response, maximizing the chances of survival.
