Defibrillator analyzers automate the inspection and preventive maintenance (IPM) testing of defibrillators. They need to be able to test at least four basic defibrillator performance characteristics: discharge energy, synchronized-mode operation, automated external defibrillation, and ECG monitoring. We prefer that they also be able to test a defibrillator's external noninvasive pacing function--but this is not essential if a facility already has a pacemaker analyzer that can perform this testing. In this Evaluation, we tested seven defibrillator analyzers from six suppliers. All seven units accurately measure the energies of a variety of discharge wave-forms over a wide range of energy levels--from 1 J for use in a neonatal intensive care unit to 360 J for use on adult patients requiring maximum discharge energy. Most of the analyzers are easy to use. However, only three of the evaluated units could perform the full range of defibrillator tests that we prefer. We rated these units Acceptable--Preferred. Three more units could perform four of the five tests, they could not test the pacing feature of a defibrillator. These units were rated Acceptable. The seventh unit could perform only discharge energy testing and synchronized-mode testing and was difficult to use. We rate that unit Acceptable--Not Recommended.
除颤器分析仪可自动对除颤器进行检查和预防性维护（IPM）测试。它们需要能够测试至少四项基本的除颤器性能特征：放电能量、同步模式操作、自动体外除颤以及心电图监测。我们希望它们还能够测试除颤器的外部无创起搏功能——但如果医疗机构已经拥有能够进行此项测试的起搏器分析仪，这一点并非必不可少。在本次评估中，我们测试了来自六个供应商的七台除颤器分析仪。所有七台设备都能在很宽的能量水平范围内准确测量各种放电波形的能量——从新生儿重症监护病房使用的1焦耳到需要最大放电能量的成年患者使用的360焦耳。大多数分析仪易于使用。然而，在评估的设备中，只有三台能够进行我们所希望的全部除颤器测试。我们将这些设备评为“可接受——首选”。另外三台设备能够进行五项测试中的四项，但无法测试除颤器的起搏功能。这些设备被评为“可接受”。第七台设备只能进行放电能量测试和同步模式测试，而且使用起来很困难。我们将该设备评为“可接受——不推荐”。
