In comparing adult and child CPR, what is a true statement?

The statement that cardiac arrest in children is usually caused by prolonged respiratory depression is true and highlights a critical difference between adult and child CPR. In children, respiratory issues, such as choking or severe asthma attacks, can lead to a lack of oxygen, resulting in respiratory failure, which then evolves into cardiac arrest. This understanding is essential when performing CPR on children, as responders should be particularly vigilant about addressing any respiratory problems as part of the emergency response.

In contrast, adult cardiac arrests are typically more often associated with cardiac events like myocardial infarctions, making the causes of arrest distinct between adults and children. Recognizing that pediatric arrest may begin with respiratory failure emphasizes the importance of maintaining effective ventilation and quickly addressing any breathing issues when initiating CPR in children.

The other statements are not accurate reflections of CPR protocols or conditions specific to child and adult emergencies.
