Answer :
Final answer:
A Yankauer suction catheter is used to clear the oral cavity during surgical procedures or after injury, to maintain an open airway by removing obstructive secretions or fluids, and is often used in tonsillectomies.
Explanation:
A Yankauer suction catheter, also known as a tonsil tip suction, is a medical device specifically designed for suctioning in oral surgery and airway clearance. It is typically used to clear the oral cavity during surgical procedures or after injury, and to maintain an open airway by removing secretions, blood, or other fluids that could obstruct the throat. The Yankauer suction catheter is therefore an important instrument in tonsillectomy procedures and other medical situations that require a clear airway, such as during the administration of the Heimlich maneuver or when an individual is at risk of aspirating fluids into the lungs.
