Which statement best describes how cricoid pressure is applied?

• A. Apply forward pressure to the cricoid cartilage toward the chin.
• B. Gently press the cricoid cartilage backward against the spine with the thumb and forefinger.
• C. Push on the arytenoid cartilage to seal the airway.
• D. Lift the larynx to improve airway patency.

Answer: (B)

Cricoid pressure aims to occlude the esophagus to reduce the risk of aspiration during airway management. The cricoid cartilage sits directly in front of the esophagus, so applying a gentle backward force on the cricoid toward the spine compresses the esophagus between the cricoid and the spine. Using the thumb and forefinger provides steady, controlled contact to maintain this posterior pressure. Pushing forward toward the chin would not close the esophagus and can distort airway anatomy, while pressing on the arytenoid cartilage or lifting the larynx does not seal the esophageal passage. This backward, posterior pressure is the mechanism used to achieve the intended protection during induction or sedation.
