What is the purpose of Sellick's Maneuver?

Sellick's Maneuver, also known as cricoid pressure, is specifically designed to provide direct downward pressure on the thyroid cartilage during airway management. This technique has historically been used to occlude the esophagus, thereby reducing the risk of regurgitation and aspiration during intubation, especially in patients who may have an elevated risk for these complications.

By applying pressure to the cricoid cartilage, it helps to compress the esophagus against the spine, theoretically preventing any stomach contents from entering the airway. This is particularly important in emergency situations, where maintaining a patent airway while ensuring patient safety is critical.

Other choices, such as lifting the epiglottis or stabilizing the airway, do not accurately reflect the primary intent of Sellick's Maneuver, making them less relevant. While this maneuver plays a role in the broader context of airway management, its specific function is centered around the control of the esophagus and reducing aspiration risk. Intubation is a separate process that may require Sellick's Maneuver to be effective, but the maneuver itself does not encompass the entire intubation procedure.
