Where is Sellick's maneuver applied?

Sellick's maneuver, also known as cricoid pressure, is applied to the cricoid cartilage, which is located just below the thyroid cartilage in the neck. This technique is primarily used during rapid sequence intubation to prevent regurgitation and aspiration of stomach contents into the airway. When pressure is applied to the cricoid cartilage, it compresses the esophagus against the cervical spine, thereby reducing the risk of aspiration during intubation.

This maneuver is particularly significant in emergency situations, where intubation is necessary, and the patient may have a full stomach or other risks for aspiration. By targeting the cricoid cartilage, the maneuver effectively facilitates safer intubation procedures, making it an essential skill for medical professionals.

Other locations mentioned, such as the thyroid cartilage and the epiglottis, do not provide the same protective effect against aspiration. The supraglottic area is more involved with airway management devices rather than the specific actions related to Sellick's maneuver. Hence, understanding the correct application of cricoid pressure highlights its importance in airway management and emergency medicine practices.
