What is the purpose of the Sellick maneuver?

The Sellick maneuver is specifically designed to apply cricoid pressure to the cricoid cartilage, which helps occlude the esophagus and prevent regurgitation and subsequent aspiration of gastric contents during intubation. This technique is particularly important in emergency situations where rapid sequence intubation is performed, as it reduces the risk of aspirating stomach contents into the lungs which can lead to serious complications such as aspiration pneumonia.

In addition to its protective function, the maneuver also serves to maintain a clear airway for the intubator, making the process of placing the endotracheal tube easier and more efficient. By preventing aspiration, the Sellick maneuver enhances patient safety during the critical moments of airway management.
