Fig. 1From: Is there an optimal place to hold the endotracheal tube during direct laryngoscopy for patients undergoing surgery under general anesthesia? Protocol for a randomized controlled trialFigure illustrating how the torque varies with the point at which the endotracheal tube is held ( P1, 2, 3); as thedistance from the tip increases ( P3), lesser is the torque making for easier fine adjustments to the movements ofthe tube tipBack to article page
