Procedural Sedation Practice Exam

Maintaining airway patency in sedated patients with reduced pharyngeal tone relies on a device that physically prevents the tongue and soft tissues from blocking the back of the throat. An oropharyngeal airway sits in the mouth and props the tongue forward, keeping the posterior pharynx open while the patient continues to breathe spontaneously. It’s quick to insert, non-invasive, and effective for this situation, making it the first choice to maintain patency. In contrast, an endotracheal tube provides a secured airway with controlled ventilation but is more invasive and reserved for situations requiring definite airway protection or ventilation support. A laryngeal mask airway is a supraglottic device used when more support is needed than a simple mask but is still more invasive than an oropharyngeal airway. A nasal cannula delivers oxygen but does not prevent airway collapse from reduced tone.
