How long should cricoid pressure be maintained during an emergency?

Cricoid pressure, also known as Sellick's maneuver, was traditionally used to prevent regurgitation and aspiration during intubation by applying pressure to the cricoid cartilage, thereby compressing the esophagus. However, recent guidelines have moved away from recommending its use in many situations due to concerns about its effectiveness and potential complications, such as airway obstruction or injury to the patient.

Current protocols emphasize recognizing that cricoid pressure should not be routinely used in emergency situations. Its application has been criticized for not significantly reducing the likelihood of aspiration compared to other methods of airway management. Emergency medical technicians are trained to consider alternative methods of airway protection and securing the airway that are more effective and safer for the patient. This shift in practice reflects a broader understanding of airway management and emphasizes patient safety, thus leading to the conclusion that cricoid pressure should not be employed in an emergency context.
