A 6-month-old infant is found unresponsive and apneic. The parents state the infant had a sudden episode of crying and turned blue. There is no obvious trauma. What is the most likely underlying cause of cardiac arrest in this infant?

Sudden Infant Death Syndrome (SIDS) Respiratory arrest Cardiac arrhythmia Aspiration of foreign body

Correct Answer:

Respiratory arrest

Explanation:

In infants, cardiac arrest is most commonly secondary to respiratory compromise leading to hypoxia, then bradycardia, and finally asystole. While SIDS is a diagnosis of exclusion and foreign body aspiration is a possibility, respiratory arrest is the most common pathway to cardiac arrest in non-traumatic settings for this age group.
