What is the compression-to-ventilation ratio for adult CPR according to the latest guidelines?

The correct compression-to-ventilation ratio for adult CPR is 30 compressions to 2 breaths. This guideline is based on evidence suggesting that this ratio is most effective for maintaining blood flow and oxygenation during a cardiac arrest scenario.

During cardiopulmonary resuscitation, chest compressions are crucial for creating artificial circulation, which is vital for keeping vital organs, especially the brain, supplied with blood. The ratio of 30 compressions before delivering 2 rescue breaths has been established as a balance that maximizes the number of compressions given while ensuring that ventilation is also provided, thus supporting the overall effectiveness of CPR.

This guideline applies to both laypersons and trained responders when performing CPR on adults, reinforcing the importance of high-quality compressions with minimal interruptions. The focus on ensuring a higher number of compressions within each cycle emphasizes the need for rapid and effective interventions during cardiopulmonary emergencies.
