Which common device is used to provide supplemental oxygen during sedation?

The use of a nasal cannula is common for providing supplemental oxygen during sedation due to its effectiveness and patient comfort. A nasal cannula consists of two small prongs that fit into the nostrils, allowing for supplemental oxygen to be delivered directly to the patient while still enabling them to talk, eat, and breathe normally through their mouth. It is particularly useful in sedation situations because it allows for a lower flow rate of oxygen, which is often sufficient to maintain adequate oxygen saturation without being invasive.

Other devices, while they can also deliver supplemental oxygen, may not be as suitable for sedation procedures. A face mask covers the nose and mouth and can be more cumbersome or uncomfortable for the patient. An endotracheal tube is used for securing the airway and delivering oxygen during anesthesia or critical care situations; it is an invasive option not ideal for situations requiring light sedation. The Venturi mask can deliver a precise concentration of oxygen but is typically not as commonly used in sedation settings where less-invasive options, like a nasal cannula, are more appropriate.
