Tube angle-modification in the angle-modified double-lumen tube group.
OA, oral axis; PA, pharyngeal axis; (A) With the patient’s head in the sniffing position, the oral and pharyngeal axes were assessed on the lateral side of the face. (B) The distal tip of the tube was positioned at the upper margin of the cricoid cartilage. (C) The tube shaft was bent at the intersection of the imaginary oral and the pharyngeal axes in order to produce a fluent curve.
