How can cricoid pressure assist with intubation?

Cricoid pressure, also known as the Sellick maneuver, is primarily used to prevent regurgitation and aspiration during intubation by applying pressure to the cricoid cartilage, which compresses the esophagus. This technique minimizes the risk that stomach contents will enter the airway, which is a critical consideration in emergency and surgical settings. It effectively reduces the likelihood of aspiration because it creates a barrier that decreases the chances of vomit or other regurgitated fluids passing into the trachea when a patient is intubated.

While other elements related to intubation, such as visualization of the vocal cords or stabilization of the head and neck, are important, they do not directly connect to the core function of cricoid pressure. The successful application of cricoid pressure is specific to managing airway safety through the prevention of aspiration, underscoring its importance in procedures involving general anesthesia or emergency resuscitation.
