Which airway adjunct is typically used for sedation?

The nasal airway is a commonly used airway adjunct during sedation procedures because it ensures that the airway remains open while minimizing the risk of airway obstruction. It is designed to be inserted into the nasal passage, extending to the oropharynx, which aids in maintaining patency of the airway. This is particularly important when patients are sedated, as they may lose protective airway reflexes, increasing the risk of airway compromise.

Using a nasal airway is advantageous due to its ease of insertion and the comfort it offers when compared to other adjuncts. It allows for spontaneous ventilation and is beneficial for patients who are semi-conscious or have decreased levels of arousal, which is often the case during moderate sedation.

On the other hand, an endotracheal tube is typically used for deeper levels of sedation or general anesthesia, as it provides a secured airway that prevents aspiration but is more invasive. A tracheostomy tube is a more permanent solution for long-term airway management and is not commonly used in moderate sedation scenarios. Finally, a Venturi mask is a device designed to provide controlled oxygen delivery and does not serve the purpose of maintaining airway patency like the nasal airway does. Hence, the nasal airway is the most suitable adjunct for procedures involving moderate sedation.
