Indication when upper airway obstruction due to soft tissue or tongue (excluding epiglottis) in a conscious or unconscious patient with a healthy gag reflex and when extensive tissue damage around the mouth and jaw and chin wiring is not possible. It is used in the case of pharyngeal edema or excessive nasal discharge in children to reduce soft tissue damage when nasal tracheal suctioning is frequently required. Nasal airway placement stimulates the patient's nausea reflex. If the tube is too long, it may enter the esophagus and cause the stomach to dilate. Epistaxis may occur and cause blood to be aspirated. The nasal airway should not be used for patients with extensive facial trauma or a fracture of the basilar portion of the cranial base. Choose the nostril that is larger and more open. Examine the passageway for trauma and foreign body wall deviation or polyps. Prepare suction devices for use if necessary. Measure the length of the nasopharyngeal airway from the tip of the nose to the edge of the ear. Nasal bleeding, aspiration, secondary hypoxia with incorrect placement. The endotracheal tube may be inserted through the nose or mouth. The placement method is visible using a laryngoscope and blindly through the nose. The goal is to establish a safe and efficient air route. Protection of trachea and lungs from aspiration of gastric, blood, and fluid contents from airway compartments, airway for mechanical ventilation, direct access to lungs for excretion or suction, discharge of emergency drugs for rapid absorption through bronchial tree.
