Which of the following is NOT a purpose of using an oral or nasal airway in an unresponsive infant or child?

The purpose of using an oral or nasal airway in an unresponsive infant or child primarily revolves around maintaining a clear and patent airway, facilitating suctioning if necessary, and assisting in managing airway obstructions.

Maintaining an open airway is critical because unresponsiveness can lead to the tongue falling back and obstructing the airway. The use of an airway adjunct helps to prevent this. Similarly, oral suctioning may be required in unresponsive patients to clear secretions and other obstructions; the airway adjunct is designed to facilitate this process as it provides better access and protection.

When it comes to intubation, while an airway adjunct can serve as an important step in airway management, it does not eliminate the need for intubation if the patient requires it. However, in emergency scenarios, having an airway device can sometimes reduce the immediate need for intubation by stabilizing the airway.

Replacing manual head positioning is not a recognized purpose of using an airway adjunct. In fact, head positioning techniques are vital for ensuring airway patency, especially in infants and small children, and adjuncts do not serve as a substitute for proper positioning.
