The correct compression to ventilation ratio for adult CPR is 30:2. This ratio is established guidelines set by organizations such as the American Heart Association and the European Resuscitation Council. It reflects the current best practice to effectively deliver high-quality CPR.

In adult CPR, the emphasis is on high-quality chest compressions, which are crucial for maintaining blood circulation until advanced medical help arrives. The 30:2 ratio indicates that for every 30 chest compressions given, 2 rescue breaths should be administered. This approach helps to ensure that the victim receives adequate oxygenation while maintaining sufficient blood flow through compressions.

Other ratios, such as 15:2 or 10:1, may be appropriate in different contexts or for different age groups. For example, the 15:2 ratio is used for child CPR with 2 rescuers, while 10:1 may apply to specific circumstances. However, for adult CPR, the standard and widely accepted practice is to maintain the 30:2 ratio to maximize the chances of survival and recovery.
