What is the recommended compression to ventilation ratio for pediatric CPR when one rescuer is present?

The recommended compression to ventilation ratio for pediatric CPR when one rescuer is present is 30:2. This ratio is designed to ensure that the child receives adequate chest compressions while also receiving necessary ventilations. In pediatric patients, high-quality chest compressions are crucial for maintaining circulation and ensuring that blood continues to flow to vital organs, while the rescue breaths provide oxygen to the lungs.

The 30:2 ratio is particularly effective because it allows for a higher number of compressions in a shorter amount of time, aligning with guidelines that stress the importance of maintaining a compression rate of 100 to 120 compressions per minute. This rhythm enables better hemodynamic performance during CPR, which is critical in an emergency situation.

Understanding this ratio is essential for effective resuscitation, as it balances the need for compressions, which help maintain blood flow, with the need for ventilations, which provide oxygen to the patient. The other ratios listed do not align with current guidelines and would not provide the same level of effectiveness in a resuscitation scenario.
