What is the purpose of the cricoid pressure (Sellick maneuver)?

The purpose of cricoid pressure, also known as the Sellick maneuver, primarily focuses on preventing regurgitation during intubation. By applying pressure to the cricoid cartilage, the maneuver compresses the esophagus against the vertebral column, which helps reduce the risk of aspiration of gastric contents into the trachea. This is particularly crucial in patients at risk for regurgitation, such as those who are unconscious or have an altered level of consciousness.

While securing the airway and improving oxygenation are essential aspects of airway management, the specific intent of cricoid pressure is centered on minimizing the chance of gastrointestinal contents entering the airway during the intubation process. This added safety measure can be vital in preventing complications associated with aspiration, which can lead to severe respiratory issues and further morbidity. Therefore, understanding the role of cricoid pressure in this context significantly enhances the effectiveness of airway management in emergency settings.
