Chest compression to ventilation ratio in resuscitation of children with 2 rescuers is
## **Core Concept**
The American Heart Association (AHA) and other international guidelines provide standardized ratios for chest compressions to ventilation (C:V) during cardiopulmonary resuscitation (CPR) that vary based on the number of rescuers and the age of the patient. For pediatric CPR, which includes children from infancy to adolescence, specific ratios are recommended to ensure effective circulation and oxygenation.
## **Why the Correct Answer is Right**
In pediatric CPR with two rescuers, the recommended chest compression to ventilation ratio is 15:2. This ratio is chosen to provide adequate circulation through chest compressions while also ensuring sufficient ventilation to support oxygenation and removal of carbon dioxide. The 15:2 ratio is specifically recommended for children because their cardiac arrest is more likely to be due to respiratory causes, and they require both effective ventilation and circulation.
## **Why Each Wrong Option is Incorrect**
- **Option A:** A ratio of 30:2 is actually recommended for adult CPR with two rescuers, not for pediatric CPR. This ratio reflects the different underlying causes of cardiac arrest in adults, which are more commonly due to cardiac causes.
- **Option B:** A ratio of 20:2 might seem plausible but is not the recommended ratio for pediatric CPR with two rescuers. The specific ratio can depend on the age of the child and the clinical scenario, but 15:2 is the standard for children.
- **Option D:** A ratio of 3:1 or 5:1 is sometimes used in neonatal resuscitation or for single rescuer situations in pediatric CPR but is not the standard ratio for two rescuers performing CPR on children.
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that the American Heart Association recommends a 15:2 ratio for two-rescuer CPR in children (from 1 year to puberty), emphasizing the importance of both effective chest compressions and ventilation. For infants and children with a single rescuer, a ratio of 30:2 is often used, similar to adult CPR.
## **Correct Answer:** C. 15:2.
