What is the compression ratio for adult CPR?

The correct compression ratio for adult CPR is 30:2. This means that for every 30 chest compressions given, there should be 2 rescue breaths administered. This ratio has been established to provide effective blood circulation and air supply during cardiopulmonary resuscitation. The focus on performing high-quality chest compressions is critical, as they maintain circulation to vital organs until professional help arrives or the individual begins to show signs of recovery.

The choice of 30:2 helps to ensure a balance between compressions that generate blood flow and breaths that provide oxygen. This optimal ratio is particularly emphasized in layperson CPR training and is widely adopted in many CPR guidelines, demonstrating its importance in effectively managing cardiac arrest situations.
