How many breaths should you give after 30 compressions in CPR?

In CPR, after performing 30 chest compressions, the protocol is to give 2 rescue breaths. This guideline is based on the standard CPR technique for adults and children, which emphasizes the importance of providing adequate ventilation following compressions to help circulate oxygenated blood to the vital organs.

The reasoning behind administering 2 breaths is to ensure that sufficient air is delivered into the lungs, allowing for effective oxygen exchange. Each breath should be given over about 1 second, enough to make the chest rise visibly. This approach is designed to maximize the chances of restoring a normal heart rhythm and maintaining brain and organ function until further medical assistance can be provided.

Other options suggest varying numbers of breaths, which are not consistent with current CPR guidelines and could potentially lead to inadequate rescue efforts.
