What is the recommended compression to ventilation ratio for adult CPR?

The recommended compression to ventilation ratio for adult CPR is 30:2. This means that for every 30 chest compressions performed, 2 rescue breaths should be given. This ratio is crucial because it optimizes the balance between providing sufficient circulation to the body through chest compressions and delivering oxygen to the lungs through ventilation, thereby improving the chances of survival in an adult experiencing cardiac arrest.

In adult CPR, continuous chest compressions are emphasized as the primary means of maintaining blood flow to vital organs. The 30:2 ratio is supported by guidelines provided by organizations such as the American Heart Association, which reflect extensive research on the effectiveness of CPR techniques. This method ensures there are enough compressions to achieve adequate blood circulation while also allowing for critical moments to ventilate, focusing on the rhythm and efficiency necessary during the stressful and demanding circumstances of cardiac arrest.
