"At first glance, it may appear as a malpositioned endotracheal tube; differentiating an endobronchial blocker from an endotracheal tube may be difficult. Still, a potential distinguishing feature is that the distal tip tends to be blunted, whereas endotracheal tubes typically have a bevelled edge. Furthermore, distinguishing an endobronchial tube from a double-lumen endotracheal tube may be difficult."
