Using the reported searches, 260 papers were found of which one presented the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of this best paper are tabulated. It is concluded that transtracheal ultrasonography may be a supplementary tool for establishing the correct tracheal tube placement in cardiac arrest. Further work is needed.
