What is the most common complication leading to pediatric cardiac arrest?

Respiratory compromise is recognized as the most common complication leading to pediatric cardiac arrest because children are particularly vulnerable to issues related to breathing. In this age group, respiratory conditions such as asthma, pneumonia, or airway obstructions can quickly escalate and lead to hypoxia—an insufficient supply of oxygen to the body. When the body is deprived of oxygen, it can result in a cascading effect that culminates in cardiac arrest.

Unlike in adults, where cardiac causes of arrest are more prevalent, children often experience cardiac arrest secondary to respiratory failure. This highlights the importance of recognizing and promptly managing respiratory distress in pediatric patients. In emergency situations, ensuring the airway is clear and the child is breathing adequately can prevent deterioration into more severe complications, including cardiac arrest, which underscores the critical nature of respiratory support in this population.
