These {\textquotedblleft}never events{\textquotedblright} are associated with significant morbidity and mortality especially when unrecognized or when there is delayed recognition. Here, we review the currently available techniques for confirming endotracheal tube intubation and their limitations, and present the case for the application of portable handheld point-of-care ultrasound as an emerging technology for detection of potentially unrecognized esophageal intubations such as during cardiac arrest. We also provide algorithms for confirmation of tracheal intubation.}, issn = {0020-1324}, URL = {https://rc.rcjournal.com/content/67/5/607}, eprint = {https://rc.rcjournal.com/content/67/5/607.full.pdf}, journal = {Respiratory Care} }
