一句话总结

论文报道了一种基于 Stifneck Select 颈圈的免手持传感器附件，用于半自动超声多普勒血流测量，在102名健康志愿者的研究中评估其舒适度、疼痛、支撑、多普勒信号可行性和皮肤安全性。

ABSTRACT

Objective: The percentage of long-term survival in out of hospital cardiac arrest cases is remarkably low. One approach would be to increase the effectiveness of cardiopulmonary resuscitation (CPR), which is currently not measurable in a quantifiable way. The most significant challenge in providing a mobile solution for CPR evaluation is a mobile, hazard free sensor attachment with high usability. Methods: We present a sensor attachment solution usable for semiautomatic ultrasonic (US) Doppler measurements. Components are attached to a Stifneck Select Collar$^{\mathrm{TM}}$ (Laerdal). An inflatable cushion (TR-Band$^{\mathrm{TM}}$, Terumo) allows adjustable contact pressure. A clinical study was conducted in which the system was evaluated based on comfort, pain, sensor support, the viability of Doppler signals, and the absence of skin irritations. Results: The system was utilized in a prospective study involving 102 healthy probands. On a scale between 1 (Low) and 10 (Intense), ratings were 1.19 (SD 0.46), 6.52 (SD 1.78), and 9.95 (SD 0.32) for pain, comfort, and support, respectively. The average duration of application was 31.19 minutes (SD 16.75 minutes). Audible Doppler signals were achieved in 92.2 % of the probands, and Doppler curve evaluation was usable in 73.5 %. No skin irritations were observed. Conclusion: A hands free sensor attachment for a US probe was developed that caused no significant complaints by healthy study volunteers. Medical users assessed its attachment as robust. Significance: With its adjustable positioning and easy attachment, the Stifneck modification can form a basis for a mobile US Doppler device, capable of evaluating carotid artery flow during CPR.

研究动机与目标

• 开发并评估用于半自动 US Doppler 测量的移动、无风险传感器附件。
• 评估健康志愿者的舒适度、疼痛、传感器支撑、多普勒信号可行性及皮肤安全性。
• 确定在 CPR 过程中使用基于 Stifneck 的附件评估颈动脉血流的可行性。

提出的方法

• 将 US Doppler 传感器连接到带有可充气垫（TR-Band）的 Stifneck Select Collar，以实现可调接触压力。
• 进行前瞻性研究，招募102名健康志愿者。
• 收集对疼痛、舒适和支撑的主观评分；测量佩戴时长；评估多普勒信号的可用性和可用性；检查皮肤刺激情况。

实验结果

研究问题

• RQ1 基于 Stifneck 的附件是否能够为 CPR 情景提供免手持、手机般的US Doppler测量方案？
• RQ2 在长时间使用中，该附件的舒适度、疼痛和支撑水平如何？
