In the recent article from Hargrave et al., their figure 1 illustrates how a clamp is commonly applied to a double lumen endotracheal tube. The authors state: “Supporting the antiviral filter prevents dislodgement of the double lumen tube or bronchial blocker.” Although supporting the antiviral filter may help prevent dislodgement of the double lumen endotracheal tube, the weight of the tubing clamp as illustrated may be a factor in dislodging the double lumen endotracheal tube. Also, if the airway gradually narrows as one moves deeper into the bronchial system, the inflation of the bronchial cuff would tend to create a force that works to push the double lumen endotracheal tube out.

An alternative technique is to apply the clamp so that the finger rings are directed downward and toward the patient. A drape clamp...
