What is the recommended compression-to-breath ratio during pediatric cardiac arrest?

1. 15:2

2. 30:2

3. 20:2

4. 10:1

The correct answer is: 30:2

The recommended compression-to-breath ratio during pediatric cardiac arrest is 30:2. This ratio is critical because it reflects the best practice for optimizing both blood flow and oxygenation during cardiopulmonary resuscitation (CPR) for children. In pediatric patients, effective chest compressions are essential for maintaining circulation and delivering oxygen to vital organs. The 30:2 ratio allows for a greater number of compressions to be performed in a shorter amount of time compared to other ratios, thereby maximizing the chances of a successful return of spontaneous circulation. Additionally, maintaining a consistent rhythm during CPR can help improve the overall effectiveness of the resuscitation efforts. Other ratios listed do not provide the same balance of compressions and breaths, which could compromise the effectiveness of CPR. For instance, ratios that have fewer compressions may lead to inadequate circulation during the critical moments of cardiac arrest. Thus, the 30:2 compression-to-breath ratio is specifically established in resuscitation guidelines to enhance the chances of survival and recovery in pediatric cardiac arrest situations.
