Basic Life Support (BLS) Practice Exam

What is the correct ventilation rate for a pediatric patient in respiratory arrest?

1. 1 ventilation every 2 to 3 seconds

2. 1 ventilation every 5 seconds

3. 2 ventilations every 15 seconds

4. 1 ventilation every minute

The correct answer is: 1 ventilation every 2 to 3 seconds

The appropriate ventilation rate for a pediatric patient in respiratory arrest is one ventilation every 2 to 3 seconds. This guideline is based on the need to provide effective ventilatory support without causing excessive inflation of the lungs or increasing intrathoracic pressure too rapidly. In pediatric patients, the respiratory rate is typically faster than that of adults, and therefore, a more frequent ventilation approach is necessary to adequately address their needs. Administering one ventilation every 2 to 3 seconds allows for a rate of approximately 20 to 30 breaths per minute, which aligns with the normal respiratory requirements for children during an emergency situation. This method ensures that oxygen is delivered effectively while minimizing the risks associated with over-ventilation, which can lead to complications such as barotrauma or decreased venous return due to increased intrathoracic pressure. Achieving a balance between providing sufficient oxygen and avoiding harm is crucial in pediatric resuscitation.
