What is the recommended technique to use when performing CPR on an adult?

The recommended technique for performing CPR on an adult is a cycle of 30 chest compressions followed by 2 rescue breaths. This method has been established as the standard guideline because it effectively maintains blood circulation and assists in oxygenating the blood during cardiac arrest scenarios.

The 30 compressions help to provide the necessary blood flow to vital organs, particularly the brain and heart, by artificially pumping the heart's blood. The subsequent 2 rescue breaths are crucial for delivering oxygen to the lungs and ensuring that some air enters the bloodstream. This combination emphasizes the importance of high-quality chest compressions while still incorporating rescue breaths to maximize the chances of survival.

In adult CPR, maintaining the correct ratio of compressions to breaths is vital for maintaining the effectiveness of the resuscitation effort. Following this guideline ensures that rescuers can provide the best chance of revival until emergency medical services arrive.
