Final answer:
The Nasopharyngeal Airway (NPA) is used to maintain an open airway by being inserted into the nostril, aiding in bag-mask ventilation. Intubation is a broader term, often used in emergencies when the airway is compromised and involves inserting a tube into the trachea.
Step-by-step explanation:
The Nasopharyngeal Airway (NPA) is designed to maintain an open airway by being inserted into a patient's nostril. The purpose of an NPA is to ensure the airway stays clear, particularly if the patient cannot maintain it themselves due to unconsciousness or reduced consciousness. Intubation is a related procedure, often used by ambulance crews, that involves placing a tube into the respiratory system to aid breathing when it is blocked or compromised.
For insertion of an NPA, the correct choice is option b: To facilitate bag-mask ventilation; Inserted into the nostril. It is gently inserted into one of the nostrils and advanced into the oropharynx to keep the airway unobstructed. This is crucial when nasal cavities are preferred for air passage or when the patient's mouth is not accessible or cannot be opened.
During respiratory emergencies, the pharynx plays a key role as it connects the nasal cavity and the mouth to the larynx and esophagus. It acts as a pathway for both air and swallowed substances, forming a part of the respiratory and digestive systems. Intubation specifically aims to manage airways for patients and may involve placing a tube directly into the trachea to facilitate breathing when the usual air passages are blocked.
