Assessment and comparison of the electrical parameters (energy, current, first and second phase waveform duration) among eighteen AEDs.
Engineering bench tests for a descriptive systematic evaluation in commercially available AEDs. AEDs were tested through an ECG simulator, an impedance simulator, an oscilloscope and a measuring device detecting energy delivered, peak and average current, and duration of first and second phase of the biphasic waveforms. All tests were performed at the engineering facility of the Lombardia Regional Emergency Service (AREU).
Large variations in the energy delivered at the first shock were observed. The trend of current highlighted a progressive decline concurrent with the increases of impedance. First and second phase duration varied substantially among the AEDs using the exponential biphasic waveform, unlike rectilinear waveform AEDs in which phase duration remained relatively constant.
There is a large variability in the electrical features of the AEDs tested. Energy is likely not to be the best indicator for strength dose selection. Current and shock duration should be both considered when approaching the technical features of AEDs. These findings may prompt further investigations to define the optimal current and duration of the shock waves to increase the success rate in the clinical setting.
评估和比较 18 种除颤器的电参数（能量、电流、第一和第二相波持续时间）。
对商业上可用的除颤器进行工程台架测试，进行描述性系统评估。通过心电图模拟器、阻抗模拟器、示波器和能量输送、峰值和平均电流以及双相波第一和第二相持续时间检测设备对除颤器进行测试。所有测试均在伦巴第地区紧急服务局（AREU）的工程设施中进行。
在首次电击时观察到输送的能量有很大差异。电流趋势显示出与阻抗增加同时逐渐下降。使用指数双相波的除颤器之间的第一和第二相持续时间有很大差异，而线性波除颤器的相持续时间相对恒定。
测试的除颤器的电气特性有很大的可变性。能量可能不是强度剂量选择的最佳指标。在研究除颤器的技术特性时，应同时考虑电流和电击持续时间。这些发现可能会促使进一步的研究，以确定冲击波的最佳电流和持续时间，以提高临床环境中的成功率。
