Summary Accuracy, ease and speed of recognition of tracheal tube position were assessed using the oesophageal detector device in a series of 40 tests on 29 patients. A single blind method was used, with each paramedic performing a single test on each patient. The tests were randomly split between two groups consisting of those tests performed on the tracheal or oesophageal tube respectively. Of the 40 tests performed, 21 were on tracheal tubes and 19 on oesophageal tubes. Correct placement was diagnosed with 100% accuracy by the paramedics, none of whom had previously used the oesophageal detector device. Each paramedic also graded speed of recognition of position and ease of use of the device. Recognition of position was graded as instant in 37 out of 40 tests. Use of the oesophageal detector device by previously inexperienced paramedics has thus been shown to be accurate, rapid and easy to learn.
