During CPR, how many compressions are typically given before breaths?

In a standard CPR protocol, especially as outlined by organizations such as the American Heart Association, the recommended ratio of chest compressions to rescue breaths for adult patients is 30 compressions followed by 2 breaths. This approach allows for a consistent and effective rhythm during chest compressions, maximizing blood circulation and maintaining oxygenation in the patient.

Thirty compressions provide a sufficient amount of blood flow to the vital organs, particularly the brain and heart, while the subsequent breaths ensure that the patient receives the necessary oxygen. This cycle of 30 compressions followed by 2 breaths is crucial because it balances the need for mechanical circulation with the need for adequate ventilation.

Understanding this ratio is fundamental for anyone performing CPR, as it enables them to deliver effective lifesaving care in emergency situations. Other ratios, such as those mentioned in the other choices, do not align with current CPR guidelines and could lead to ineffective resuscitation efforts.
