Occupational challenges in air transport domains make auscultation with traditional stethoscopes difficult. This study aimed to investigate two commercial off-the-shelf stethoscopes for use in high noise military patient transport environments. The stethoscopes were assessed by Aeromedical Evacuation providers in a simulated C-130 trainer on live standardized mock patients. Device 1 was a dual-mode stethoscope developed for rotary wing military airframes. Device 2 was an electronic stethoscope developed for high noise civilian environments. Twenty clinicians performed cardiopulmonary auscultation using the devices on the same two standardized patients in a simulated C-130 then completed a subjective questionnaire on their ability to identify heart and lung sounds. Results indicated the dual-mode stethoscope had limited utility with clinician likeliness of use rated as low (median = 2; interquartile range = 1.75-3.25), whereas the electronic stethoscope had potential utility with likeliness of use rated as good (median = 4; interquartile range = 3.25-5). We conclude that further examination of devices capable of auscultation in high noise military environments is needed. In-flight testing of device 2 for use by end users has been completed and will be reported in a separate manuscript.
航空运输领域的职业挑战使得使用传统听诊器进行听诊变得困难。本研究旨在调查两款商用现成听诊器在高噪音军事患者运输环境中的使用情况。这些听诊器由航空医疗后送人员在模拟的C - 130训练机上对真实的标准化模拟患者进行评估。设备1是一款为旋翼军用飞机机身开发的双模听诊器。设备2是一款为高噪音民用环境开发的电子听诊器。20名临床医生在模拟的C - 130上使用这些设备对同一两名标准化患者进行心肺听诊，然后完成一份关于他们识别心肺声音能力的主观问卷。结果表明，双模听诊器的实用性有限，临床医生使用它的可能性被评为低（中位数 = 2；四分位间距 = 1.75 - 3.25），而电子听诊器具有潜在实用性，使用可能性被评为良好（中位数 = 4；四分位间距 = 3.25 - 5）。我们得出结论，需要进一步研究能够在高噪音军事环境中进行听诊的设备。设备2供最终用户进行的飞行测试已经完成，将在另一篇稿件中报告。
