How many compressions and ventilations should be given during CPR for an adult?

The correct approach for conducting CPR on an adult is to perform 30 compressions followed by 2 ventilations. This ratio is essential to maintain effective circulation and oxygenation during cardiac arrest. The 30:2 compression-to-ventilation ratio allows for rapid cardiac compressions, which are crucial in generating blood flow to vital organs. The compressions should be administered at a rate of 100 to 120 per minute, and the depth should be at least 2 inches to ensure adequate perfusion.

The two ventilations that follow the compressions are critical for providing oxygen to the lungs, but they should not significantly delay further compressions. This sequence ensures that chest compressions, which are the primary focus in CPR, are prioritized while also addressing the need for artificial ventilation to support the person’s breathing.

Overall, this method aligns with the latest guidelines established by leading organizations like the American Heart Association, reflecting the most effective practice to provide lifesaving care in cases of adult cardiac arrest.
