Verified step by step guidance

Understand the context: Cardiopulmonary arrest in infants and children is often secondary to other conditions rather than being a primary cardiac issue. This differs from adults, where myocardial infarction or arrhythmias are common causes.

Review the options: Respiratory failure, myocardial infarction, cardiac arrhythmias, and congenital heart defects. Consider the physiological differences between children and adults, as well as the prevalence of these conditions in pediatric cases.

Focus on respiratory failure: In infants and children, respiratory failure is the most common cause of cardiopulmonary arrest. This is because their respiratory systems are more vulnerable to infections, airway obstructions, and other conditions that can lead to hypoxia (low oxygen levels). Hypoxia can then lead to cardiac arrest.

Eliminate less likely options: Myocardial infarction is rare in children due to the absence of risk factors like atherosclerosis. Cardiac arrhythmias and congenital heart defects can cause cardiopulmonary arrest but are less common compared to respiratory failure.

Conclude: Respiratory failure is the most likely cause of cardiopulmonary arrest in infants and children, as it directly impacts oxygen delivery to tissues and can lead to secondary cardiac complications.
