What is the proper formula for compressions to breaths when performing CPR?

The proper formula for compressions to breaths when performing CPR is 30:2. This means that for every 30 chest compressions delivered, 2 rescue breaths should follow. This ratio is recommended for adult victims of cardiac arrest to ensure effective circulation and oxygenation. The 30:2 ratio allows for a quick and efficient cycle of compressions, which helps maintain blood flow to vital organs until professional help arrives or until an automated external defibrillator (AED) can be used.

This approach has been supported by guidelines from major health organizations, allowing providers to deliver high-quality compressions while also ensuring that the patient receives necessary breaths. The focus on this particular ratio is critical because it maximizes the chances of survival until further medical assistance is available. In other scenarios, such as in pediatric care or when two rescuers are available, different compression-to-breath ratios are applied; however, for adult CPR, 30:2 is the standard.
