During CPR, how often should compressions and breaths be given?

The recommended protocol for CPR includes performing 30 chest compressions followed by 2 rescue breaths. This specific ratio is based on guidelines established by major health organizations to maximize the chances of survival during a cardiac arrest. The compressions help to maintain blood circulation, providing essential oxygen to vital organs, while the rescue breaths deliver oxygen directly into the lungs, helping to restore normal breathing patterns.

This method is particularly effective because it balances the need for continuous circulation with the necessity of providing oxygen to the person in need. Consistently following this cycle of 30 compressions and 2 breaths ensures that both compressions and ventilation are adequately administered, which is crucial for effective resuscitation. Other options do not conform to these established guidelines or may lack the urgency and structure required during a CPR situation.
