Question: 1 / 400

What is the primary function of a nasopharyngeal airway (NPA)?

To provide oxygen to the casualty

To prevent airway obstruction

The primary function of a nasopharyngeal airway (NPA) is to prevent airway obstruction. An NPA is specifically designed to keep the upper airway open by providing a clear passage for air to flow, especially in cases where a casualty may be unconscious or semi-conscious. It is inserted through the nostril and extends into the nasopharynx, allowing for unobstructed airflow and reducing the risk of asphyxiation due to tongue displacement or other factors that could block the airway.

The effectiveness of an NPA is crucial in tactical combat scenarios where casualties may suffer from altered levels of consciousness or facial injuries. Its ability to maintain airway patency is vital for ensuring that ventilation can occur, thus preventing hypoxia and other complications associated with airway obstruction.
