What is the recommended CPR ratio of chest compressions to breaths?

The recommended CPR ratio of chest compressions to breaths is 30 chest compressions to 2 breaths. This ratio is established based on guidelines from organizations such as the American Heart Association. It emphasizes the importance of maintaining a high frequency of chest compressions to effectively circulate blood during a cardiac arrest.

By using this ratio, rescuers can provide effective compressions while ensuring that there is also sufficient oxygen delivered to the lungs. The 30:2 ratio helps maintain optimal blood flow and oxygenation, which are critical in increasing the chances of survival for an individual experiencing cardiac arrest. This approach has been shown to be effective in both adult and pediatric patients, making it a universal guideline in CPR training and response scenarios.
