The item discussed here is the Mallinckrodt size 8.5 endotracheal tube with an above-the-cuff suction port. There being millions of different types, I thought it would be better to just pick a representative style, and to discuss it. The suction port may be a bit of a gimmick, and many places don't use this style of tube. Of course, the "representative style" available to me was the one which was already unwrapped, in the ICU nurse educator's office. There are several structural features of note, which each deserve some brief mention. These features are common to the vast majority of ETTs.
