Impulse 7010, Defibrillator Selectable Load Accessory, in conjunction with Impulse 7000, Defibrillator/External Pacer Analyzer, is specifically designed by Fluke Biomedical to allow defibrillator manufactures and end users to comply with portion of IEC 60601-2-4 and AAMI DF80 standards.
Impedance in humans has been shown to vary anywhere from 25 to 180 ohms with the average impedance of an adult around 70 to 80 ohms according to an AAMI study. A well designed defibrillation waveform must measure patient impedance and adjust the waveform shape and duration accordingly to optimize waveform performance across the range of anticipated impedance values.
The "Section 6.8.3" of the IEC 60601-2-4 standard and AAMI DF80 standard require defibrillators to be tested on different resistant loads of 25, 50, 75, 100, 125, 150, and 175 ohms to ensure proper energy is delivered to patients with different impedances. Impulse 7010 is also the only testing tool to test defibrillators beyond 175 ohms. A 200 ohms option gives manufactures the capability to test defibrillators under extreme impedance conditions. In addition, interface with Fluke Biomedical Ansur, PC-based automation software, allows for standard, streamlined and time-saved operation and total digital data management.
Use of Impulse 7010 is easy. Simply connect the Impulse 7010 output connectors to the input connectors of Impulse 7000 as shown in the figure below. The various connection combinations available through the Impulse 7010's rotary switch provide eight different loads for a defibrillator discharge.
