title: Defibrillator/monitor/pacemakers.
abstract: This study updates our May-June 1993 Evaluation of defibrillator/monitor/pacemakers, published in Health Devices 22(5-6), in which we tested eight units from six suppliers. For this Update Evaluation, we tested three additional units, each from a different supplier. We also present update information, including some new ratings, for most of the previously evaluated units. We judged the new units against the same basic criteria and rated and ranked them using the same scheme--with some minor revisions--as in our original Evaluation. We judged the suitability of these units for three primary clinical applications: (1) general crash-cart use, (2) prehospital (emergency medical service [EMS]) use, and (3) in-hospital transport use. Because our criteria have changed slightly since the original study, we have repeated them in this issue. The test methods have not changed significantly and can be found in the original 1993 Evaluation. For more detailed information about this technology, the environments in which these units are used, and the factors to consider when selecting this type of device, we encourage readers to refer to the following sections in the original Evaluation: the Clinical Perspective "The Importance of Early Defibrillation"; the Clinical and Technical Overview; and the Selection and Use Guide for Defibrillator/Monitor/Pacemakers.
