What is the correct technique for performing two-rescuer CPR on a 4-year-old child?

The correct technique for performing two-rescuer CPR on a 4-year-old child involves delivering 15 compressions followed by 2 ventilations. This ratio acknowledges the more effective support that can be provided with two rescuers, allowing for an increased frequency of compressions while maintaining effective ventilation.

Using the heel of your hand for chest compressions is vital, as it helps deliver sufficient force to compress the child’s sternum to an appropriate depth, which is about one-third of the chest depth in children. This practice ensures adequate blood flow to vital organs during cardiac arrest.

By emphasizing the correct compression-to-ventilation ratio, the technique acknowledges the need for both effective compressions and adequate rescue breaths, which together improve the chances of survival and recovery for a child in need of cardiac resuscitation. The focus on achieving observable chest rise during ventilations is crucial for ensuring the breaths are effective.

Other options provided either have incorrect compression ratios or suggest depths and techniques that do not align well with pediatric CPR guidelines for a child of that age. Understanding these fundamentals is critical for successfully performing CPR on pediatric patients.
