What is the compression-to-breath ratio for adults when performing CPR?

The compression-to-breath ratio for adults when performing CPR is 30 compressions to 2 breaths. This ratio is grounded in the guidelines provided by organizations such as the American Heart Association. The primary goal during adult CPR is to maintain adequate circulation and oxygenation as quickly and efficiently as possible. The 30:2 ratio allows for a higher frequency of chest compressions, which is crucial for promoting blood flow to vital organs during cardiac arrest.

The rationale behind using 30 compressions followed by 2 breaths is focused on the emphasis of compressions, as they play a critical role in maintaining circulation. Effective chest compressions can significantly improve the chances of survival during cardiac emergencies. The two rescue breaths following every 30 compressions are intended to provide oxygen to the lungs, complementing the circulatory efforts initiated by compressions.

The other proposed ratios don't align with current CPR guidelines for adults, emphasizing the importance of adhering to the established standard of 30 compressions followed by 2 breaths for effective resuscitation efforts.
