What is the correct ratio of chest compressions to breaths in single rescuer CPR?

The correct ratio of chest compressions to breaths in single rescuer CPR is 30:2. This means that for every 30 chest compressions given, the rescuer should provide 2 rescue breaths. This approach is based on the principles of high-quality CPR, which emphasizes the importance of delivering more compressions to maintain blood circulation effectively during cardiac arrest.

The rationale behind this ratio is that chest compressions are the most critical component for maintaining blood flow to vital organs when the heart is not pumping effectively. Delivering 30 compressions allows enough time to maintain blood circulation, while the 2 rescue breaths help provide necessary oxygen to the lungs of the patient. Following this established ratio ensures that the rescuer can maximize the effectiveness of their efforts in a structured manner.

This ratio is applicable in adult CPR scenarios, and understanding this balance equips a rescuer to perform CPR effectively and potentially improve patient outcomes until advanced medical help arrives.
