Which catheter tip is recommended to suction the left mainstem bronchus?

• A. Straight tip
• B. Coude tip
• C. Rusch tip
• D. Flexible tip

Answer: (B)

Selective suctioning of a specific bronchus relies on a catheter that can be steered toward that bronchus. The left mainstem bronchus branches off the trachea at an angle that makes a straight-tip catheter likely to enter the right mainstem instead. A Coude tip has a curved distal end that can be deflected toward the left mainstem, allowing you to guide the catheter into the left bronchus for targeted suctioning. This directional control helps reach the left lung while minimizing trauma and unnecessary suctioning of the right side. Other tips lack reliable steerability toward the left mainstem, making them less effective for selective suctioning.
