The purpose of using a bag-valve-mask ventilator primarily centers on its role in assisting with ventilation for patients who are unable to breathe adequately on their own. This device allows a caregiver to manually deliver breaths to a patient by squeezing a bag connected to a face mask that fits over the patient’s nose and mouth.

In situations where a child's airway is compromised, or they exhibit signs of respiratory distress or failure, the bag-valve-mask device becomes essential. It helps create positive pressure that aids in inflating the lungs and ensures that oxygen is delivered effectively. Adequate ventilation is crucial during emergencies, and the bag-valve-mask system provides a reliable means of supplying necessary breaths until further assistance, such as advanced airway management, can be obtained.

While supplemental oxygen can be delivered through the apparatus, its primary function is to facilitate ventilation. Additionally, it does not serve the purpose of monitoring vital signs or administering intravenous fluids, distinguishing its role as integral to respiratory support in pediatric emergency care.
