主要目的：评估基于EverOn(TM)压电传感器的非接触式心率和呼吸监测系统的准确性。方法：在睡眠实验室和重症监护病房(ICU)环境中对Everon(TM)和参考设备进行测量。将参考设备和EverOn(TM)的一分钟测量结果取平均值并进行比较。结果：41名儿童和16名成人的呼吸频率(RR)准确率分别为93.1%和90.6%，心率(HR)准确率分别为94.4%和91.5%。42例ICU患者的RR准确率分别为82.0%和75%(分别与呼气末二氧化碳分压和人工呼气末二氧化碳分压比较)，HR准确率为94.0%。EverOn(TM)在测量RR方面优于阻抗技术。结论：所描述的系统符合法规和行业标准。
Primary objective: To assess the accuracy of the EverOn (TM) piezoelectric sensor based contactless heart rate and respiration rate monitoring system.Methods: Measurements of the Everon (TM) and reference devices were performed in a sleep lab and an intensive care unit (ICU) setting. One minute measurements by both the reference device and the EverOn (TM) were averaged and compared. Accuracy was defined in accordance with industry criteria.Results: Respiration rate (RR) accuracy in the 41 children and 16 adults evaluated in the sleep lab was 93.1% and 90.6% respectively, and heart rate (HR) accuracy was 94.4% and 91.5% respectively. For the 42 ICU patients RR accuracy was 82.0% and 75% (versus end-tidal CO2 and manual respectively), while accuracy of HR was 94.0%. The EverOn (TM) was found to be superior to the impedance technique in measuring RR.Conclusions: The system described was found to be accurate in accordance with regulatory and industry criteria.
