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 administered, two rescue breaths should be delivered. This ratio is designed to maximize the effectiveness of the chest compressions while ensuring that the patient receives adequate oxygenation through ventilations.

The rationale behind this specific ratio is based on recent guidelines that emphasize high-quality chest compressions as a critical component of resuscitation. Compressions should be performed at a rate of about 100 to 120 per minute, providing a consistent flow of blood to the vital organs. Following every 30 compressions with two ventilations allows for sufficient time to provide the breaths without significantly interrupting the flow of compressions.

Using a correct ratio like 30:2 helps to create a balance between compressions and ventilations, ensuring that the patient is receiving both mechanical support for circulation and oxygenation support. This approach is crucial for increasing the chances of survival following cardiac arrest.
