When performing CPR, what is the recommended compression to breath ratio?

The recommended compression to breath ratio during CPR for adults is 30 compressions followed by 2 rescue breaths. This ratio is established based on research that shows this format is effective in maintaining blood circulation while simultaneously providing oxygen to the lungs. The 30:2 ratio allows for a strong and rapid response to cardiac arrest, maximizing the number of compressions delivered, which is crucial for ensuring blood flow to vital organs during the critical moments after a person has stopped breathing or their heart has ceased functioning.

In CPR for adults, focusing on the compressions is vital because they create artificial circulation, providing oxygenated blood to the brain and other organs until professional help arrives or the victim can be revived. The ratio also simplifies the process, making it easier for rescuers to remember and perform efficiently, especially in high-stress situations.

For specific populations, such as children or infants, different ratios may apply, and it's essential to adjust your technique according to the age of the victim, but for adult CPR, the 30:2 ratio is the standard practice endorsed by guidelines from organizations such as the American Heart Association.
