Clinical tests for confirming tracheal intubation or excluding oesophageal intubation Misting • has a false positive rate of 0.69, meaning it is present in 69% of oesophageal intubations • has a positive likelihood ratio of 1.46, meaning that the presence of misting indicates that tracheal placement is only 1.46-fold more likely than oesophageal placement Chest auscultation • has a false positive rate of 0.14–0.18, meaning that 14–18% of oesophageal intubations will be incorrectly classified by this test Oesophageal detector device • has a false positive rate of 0.05; this means it will ‘miss’ 1 in 20 oesophageal intubations Chest rise • one animal study looking at 20 rats showed a false positive rate of 0.15 @VirtueOfNothing @jadamlaw @NicholasChrimes @AndyHiggsGAA @doctimcook buff.ly/3BowTSy
