LOW POWER DEVICE WITH CONTINGENT SCHEDULING

摘要

Medical device systems and methods for operating medical device systems conserve energy by efficiently managing computational demands of the systems. A first analysis, having relatively lower computational processing demand than at least a second analysis, processes signals from a subject to determine a first estimate of a propensity for the subject to have a neurological event. If the first estimate meets a set of specified criteria, a second analysis is performed to determine a second estimate of the propensity for the subject to have a neurological event.

主权项

1. A method of operating a medical device configured to monitor a subject, the method comprising:
receiving a first signal from a sensor communicating with the subject; setting a processor to a base mode configured to receive the first signal and perform a first analysis of the first signal to estimate a first neurological status of the subject; computationally determining that the first neurological status meets one or more specified criteria; transitioning the processor from the base mode to an advanced mode, the processor in the advanced mode configured to receive a second signal subsequent to the first signal and perform a second analysis of the second signal to estimate a second neurological status of the subject, the first analysis requiring less computational power than the second analysis; and receiving the second signal.
