What is the compression to ventilation ratio for children when there is 1 rescuer present?

The compression to ventilation ratio for children when there is one rescuer present is 30:2. This means that for every 30 chest compressions performed, the rescuer should provide 2 rescue breaths. This ratio is designed to maximize the effectiveness of cardiopulmonary resuscitation (CPR) in a single-rescuer scenario, ensuring that adequate blood flow is maintained through compressions while still providing necessary oxygenation through ventilations.

For children, the higher number of compressions compared to breaths reflects the emphasis on maintaining circulatory flow during an emergency. Rescuers should focus on performing compressions at a rate of 100 to 120 per minute to ensure optimal perfusion of vital organs. The 30:2 ratio is consistent across various guidelines and reflects a best practice approach in pediatric cardiac arrest situations.
