How does ventilation differ between an adult and a child in emergencies?

• A. The frequency of breaths is higher for children
• B. The volume of breaths delivered is less in children
• C. Only children require rescue breaths
• D. Adults need fewer breaths than children

Answer: (B)

The distinction in ventilation between adults and children during emergencies is particularly evident in the volume of breaths delivered. For children, due to their smaller lung capacity, the tidal volume—the amount of air delivered in each breath—is less than that of adults. This means that although children may have a higher respiratory rate, the actual volume of air they can take in with each breath is significantly lower. This lower volume is critical to understand when providing rescue breaths. Delivering breaths with too much air can cause barotrauma or hyperventilation in children. Therefore, when performing ventilation techniques such as CPR, it's essential to tailor the breath volume to the child's size and needs. In contrast, the frequency of breaths, the need for rescue breaths, and the comparison of breath rates between adults and children offer important context but do not address the fundamental mechanical differences in how much air each group can effectively exchange with each breath. Focusing on the volume helps ensure effective and safe ventilation during emergencies.
