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

The correct ratio of compressions to breaths during CPR is 30 compressions to 2 breaths. This ratio is recommended because it optimizes the effectiveness of chest compressions, which are crucial in maintaining blood flow to vital organs during cardiac arrest. The emphasis is placed on high-quality compressions that help to circulate blood effectively, while the addition of breaths provides oxygen to the lungs.

The 30:2 ratio applies in most scenarios, such as when performing CPR on adults and children. It is designed to ensure that there are enough compressions to support circulation while still incorporating rescue breaths to address the need for oxygen. This combination enhances the chances of survival and recovery for the individual experiencing cardiac arrest.

This guideline reflects current practices supported by organizations like the American Heart Association, which advocate for standardized approaches to CPR to ensure consistency and efficiency in emergency situations. Other options presented, like the 15:2 ratio or 20:1, do not align with these established protocols, leading to inefficient rescue efforts.
