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

The correct compression to ventilation ratio for adult CPR is 30:2. This means that for every 30 chest compressions administered, 2 rescue breaths should be given. This ratio is crucial as it has been established based on research that emphasizes the importance of high-quality chest compressions in maintaining blood flow to vital organs during cardiac arrest.

The focus on maintaining this specific ratio helps to ensure that sufficient oxygen is being supplied while also maximizing the effectiveness of compressions to circulate blood. The use of 30 compressions followed by 2 breaths allows responders to efficiently sustain circulation and provide oxygen to someone who is experiencing a cardiac emergency.

The other options do not align with current guidelines for adult CPR. For instance, a ratio of 15:2 would not deliver enough compressions in the critical early minutes of cardiac arrest when time is of the essence. Similarly, a ratio of 30:5 or 15:1 is not recommended, as they do not provide the ideal compromise between compressions and ventilation that is necessary to improve outcomes in respiratory and cardiac emergencies. The 30:2 ratio strikes the right balance, reflecting best practices in resuscitation efforts.
