What are the recommended compression-to-ventilation ratios for infants when there is 1 rescuer present?

The recommended compression-to-ventilation ratio for infants when there is one rescuer present is 30:2. This means that for every 30 chest compressions given, the rescuer should deliver 2 breaths. This ratio is crucial as it maximizes the effectiveness of resuscitation efforts.

In terms of physiological needs, infants have higher respiratory rates and different chest wall mechanics compared to adults, which influences how we deliver CPR. The 30:2 ratio is designed to prioritize chest compressions, which are vital for maintaining blood circulation and oxygen delivery to the brain and vital organs. The rapid cycle of compressions followed by breaths ensures that oxygenation occurs quickly after sufficient blood flow is established, which is essential in improving the chances of survival.

This approach differs from infant CPR with multiple rescuers, where the compression-to-ventilation ratio changes to 15:2. Thus, understanding the correct ratio when one rescuer is present is essential in emergency scenarios to provide effective support to an infant in cardiac arrest.
