When administering CPR, what is the correct ratio of breaths to chest compressions?

The correct ratio of breaths to chest compressions during CPR is 30 compressions for every 2 breaths. This means that after delivering 30 chest compressions to circulate blood effectively, the rescuer should provide 2 rescue breaths to help oxygenate the victim’s lungs. This method maximizes blood circulation and oxygen delivery, increasing the chances of survival in a person experiencing cardiac arrest.

The CPR guidelines emphasize this ratio because effective chest compressions are critical to maintaining blood flow to vital organs. The compression rate should ideally be at least 100 to 120 compressions per minute, and the breaths should be given after every 30 compressions to ensure that the victim receives sufficient oxygen.

In the context of the other choices, the numbers provided do not conform to the established guidelines for CPR and do not reflect an effective balance of circulation and oxygenation necessary for proper resuscitation efforts.
