Capnography and oxygenation via single-use bougie

Abstract

Letters to the editor the bougie. This is in sharp contrast to an intravenous cannula, which may be diffi cult and time-consuming to insert and remove repeatedly. We have used this modifi ed tracheal tube guide in more than 50 patients and found it to be an effective tool for capnography, using both side-stream and mainstream analyzers, and for delivering oxygen to the patient.
