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.
在对29名患者进行的一系列40次测试中，使用食管探测器评估气管导管位置识别的准确性、简易性和速度。采用单盲法，每位护理人员对每位患者进行一次测试。测试随机分为两组，分别对气管导管和食管导管进行测试。在进行的40次测试中，21次针对气管导管，19次针对食管导管。护理人员对正确放置的诊断准确率为100%，他们之前均未使用过食管探测器。每位护理人员还对位置识别速度和设备易用性进行了评分。在40次测试中，有37次对位置的识别被评为即时识别。因此，以前没有经验的护理人员使用食管探测器已被证明是准确、快速且易于学习的。
