Abstract

A modular automated external defibrillator (AED) system includes a base unit and at least one interconnected module. The base unit typically includes a functional circuit and includes an interface that couples the functional circuit to the module. Likewise, the module includes an interface that couples the module to the base unit. By manufacturing such modular AED models instead of one-piece, i.e., integrated, AED models, a manufacturer can reduce the cost and complexity of its manufacturing process. Furthermore, the manufacturer may be able to bring such a modular AED to market more quickly than it could bring an integrated model of the AED to market. Moreover, a modular AED allows the manufacturer and customer flexibility in respectively providing and selecting feature sets. In addition, a customer can obtain replacements for broken modules, and the manufacturer can provide cheaper upgrades by upgrading a module or base unit instead of upgrading the entire AED.
