Abstract: Methods, user interfaces and systems are described that enable responder preferences to be considered during deployment of a public responder network. In some embodiments, a user is able to set preferences such as a mobility status, a public accessibility preference, a incidents notifications preference or a geographic preference associated with a medical device that is a part of the public responder network. In some embodiments, the user is able to select or define an area for which incident notifications are desired or are to be restricted in some manner. The described approach is well suited for public responder networks that include medical devices such as defibrillators (e.g., AEDs) in the network.

Abstract: A variety of systems, methods, architectures and devices are described that facilitate quicker responses to potential cardiac arrest incidents in a variety of different circumstances.

Abstract: Status messages are wirelessly broadcast from medical devices (e.g., defibrillators) as advertisements that don't require the establishment of a wireless connection with listeners. The listeners are configured to act on, or forward received status messages as appropriate. The listeners may optionally include supplemental information supplied by the listener device when forwarding a status message to a management server. The listener may optionally analyze received status messages to determine whether an action should be taken based at least in part on status information in the message. Actions performed by the listener may include initiating a connection with the transmitting device to facilitate uploading new information from the defibrillator, updating the defibrillator's firmware, etc. Optionally, some of the advertisements are configured as beacons. The advertisements/beacons may be transmitted using a Bluetooth Low Energy or other suitable protocols.

Abstract: System and methods for delivering defibrillator incident information to a PSAP in real-time during emergency use of an AED are described. Such information is utilized by a telecommunicator at a PSAP to provide better guidance to volunteer caregivers during potential cardiac arrest incidents. In another aspect the AED's current instruction state and optionally the time in that state is provided to the PSAP.

Abstract: Defibrillators, defibrillator architectures, defibrillator interface units and methods of operating defibrillators are described. In one aspect, a modular defibrillator architecture is described. A base unit provides a fully functional defibrillator. The functionality of the base unit can be supplemented by attaching an interface unit to the base unit. The defibrillator interface unit includes a housing, a communications module, a processing unit and a power storage unit. The housing is configured to be mounted on the base defibrillator unit to form at least a part of a unitary portable modular AED system. The communications module facilitates wireless communication between the AED and one or more remote servers. The processing unit includes at least one processor and is configured to receive communications from the base defibrillator unit. The power storage unit powers the interface unit including the communications module and the processing unit.

Abstract: Several defibrillators, defibrillator architectures, defibrillator components and methods of operating defibrillators are described. In one aspect, a modular defibrillator architecture is described. A base unit provides a fully functional defibrillator. The functionality of the base unit can be supplemented by attaching an interface unit to the base unit or by connecting a smartphone the base unit. Such devices provide connectivity as well as a screen for displaying supplementary graphics and/or videos which are useful to support both emergency and maintenance & monitoring activities. In some embodiments a battery pack may also or alternatively be coupled to the base unit to prolong the unit's shelf life before recharging or replacement of its batteries is required. If necessary the base unit can be powered from a connected external device such as a mobile communication device.

Abstract: Several defibrillators, defibrillator architectures, defibrillator components and methods of operating defibrillators are described. In one aspect, a defibrillator (as for example an automated external defibrillator) that can be powered by a mobile communication device such as a smart cellular phone or a tablet computer is described. Utilizing a phone (or other mobile communication device) as the power supply for an external defibrillator allows the external defibrillator to be smaller and, in some circumstance, removes the need for a battery that stores sufficient energy for shock delivery—which would need to be checked and/or replaced on a regular basis. Additionally, when desired, certain control functionality, computation, data processing, and user instructions can be handled/presented by the mobile communications device thereby further simplifying the defibrillator design and improving the user experience.
