During single-provider CPR, what is the correct compression-to-ventilation ratio?

15:2
30:2
10:1
5:1

The correct answer is: 30:2

The correct compression-to-ventilation ratio for single-provider CPR is 30:2. This means that for every 30 chest compressions delivered, the provider should give 2 rescue breaths. This ratio has been established based on recent guidelines and research that have shown it to be effective in maximizing blood flow and oxygenation during cardiac arrest situations. The focus on the higher number of compressions in this ratio serves the purpose of maintaining circulation and providing essential blood flow to vital organs, particularly when the heart is not effectively pumping blood. The quick succession of compressions followed by breaths helps ensure that the body stays as oxygenated as possible until advanced medical help arrives or the individual recovers from cardiac arrest. Understanding this ratio is crucial for effective CPR, as it standardizes the process and ensures that the responder can deliver the best possible care to the victim.
