Final answer:
In Sellick's maneuver, the paramedic compresses the cricoid cartilage to assist with intubation and prevent aspiration.
Step-by-step explanation:
In order to assist with intubation, a paramedic may utilize Sellick's maneuver, which is a procedure performed to prevent aspiration during intubation or resuscitation. In this procedure, the paramedic compresses the cricoid cartilage, which is a small ring of cartilage located just below the thyroid cartilage, making up part of the larynx. This compression is aimed at closing off the esophagus, which prevents gastric content from coming up and potentially entering the airway and lungs. It's a critical procedure in emergency medicine and anesthesia to maintain an open and clear airway.
