A medical device is disclosed. The device may include a service component for use in detecting patient data, at least one processor coupled with the service component, a care protocol module executable by the at least one processor to provide healthcare to a patient at least in part by generating a request for processing by the service component, and a resource module executable by the at least one processor to manage access to the service component by identifying a level of service associated with the care protocol module and responding to the request by managing the service component to meet the level of service. The care protocol module implements a patient care protocol that includes a sequence of actions directed to the patient. The level of service indicates a level of performance that the patient care protocol requires of the resource module. Selective offloading of modular functions is also enabled.
