What is the leading cause of non-traumatic cardiac arrest in pediatrics?

The leading cause of non-traumatic cardiac arrest in pediatrics is respiratory failure. In children, respiratory conditions such as severe asthma, pneumonia, or airway obstruction can lead to inadequate oxygenation and ventilation. This lack of oxygen can cause hypoxia, leading to respiratory arrest, which can subsequently progress to cardiac arrest if not promptly addressed. The pediatric population relies heavily on their respiratory system for maintaining adequate blood oxygen levels, and any significant disruption to this system can have dire consequences.

Understanding this emphasizes the importance of addressing respiratory issues quickly in children to prevent potential cardiac arrest. The other options, although they can contribute to cardiac issues, do not represent the primary pathway leading to non-traumatic arrest in the pediatric demographic.
