Systems and techniques to ensure reliable operation of devices, such as medical devices, that are configured to execute installed software are described. A secure software update process for the device utilizes multiple integrity checks in order to prove that software integrity has not been compromised before the device is allowed to be put into service with the software installed thereon. Also described is a computer architecture for an external defibrillator that isolates the execution of installed software applications by separately compiling the code for those applications and by executing the separately-compiled applications on different processors of the defibrillator. Among other things, this allows the defibrillator to be 'brought online' faster, such as to deliver a shock to a patient.

Secure software updates and architectures

A data distribution system in comprises software application nodes that utilize a publish-subscribe communication mechanism for distribution of data in real-time or near real-time within a personal area network (PAN), local area network (LAN), or wide-area network (WAN) configuration. The distributed system communication software application nodes reside in medical devices, such as monitoring devices and cardiac defibrillators, and associated patient information delivery systems and patient data management systems comprising medical software installed on servers and end-user computing devices, including mobile devices.

Real-time data distribution system for patient monitoring devices, cardiac defibrillators and associated information delivery systems

A computing architecture, system and method are disclosed for use in a medical device for providing decision support to a caregiver. The computing architecture includes a memory, a processor in communication with the memory, and an instance of a primary rules-based service configured to provide instruction events, the instance providing a primary processing thread of instruction events for coaching treatment of a patient. A software manager module includes an artificial intelligence architecture. The artificial intelligence architecture is configured to provide an instance of a conditional rules-based service for providing instruction events. The instance provided by the artificial intelligence architecture provides a processing thread of instruction events for coaching treatment of a patient that is independent of the primary processing thread and is configured to trigger an action on the occurrence of a pre-defined set of input conditions.

Decision support system using intelligent agents

Work flows are modeled as a graph of interdependent tasks to be performed. The tasks to be performed are set by a task file module configured to enable interactions between tasks and including modules for event viewing, protocol assistance, smart messaging, smart indices, reference material lookup. A decision support manager module is configured to construct data and model profiles for storage in a data and model profile bank, events for storage in a decision support events bank, and protocols for storage in a decision support protocol bank. Configuration files are provided to specify a configuration for execution of one of the tasks. Data entered through a user interface or from a network via a wireless or wired communication module may define task files in the task files module, configuration files in the configuration files module, as well as data, events, and protocols to be used for a defibrillation procedure. A decision support manager module is configured to construct a dependency graph of tasks as specified in at least one of the configuration files and to execute the dependency graph.
