1. A system for context-sensitive monitoring of sensor performance for an arterial flow system, comprising the following computer-executable components: a sensor interface component that obtains sensor data from a plurality of sensors; a context analyzer component that analyzes contextual data received from at least one data source, the contextual data being associated with the sensor data; a sensor analyzer component that identifies which of the sensor data is degraded based at least in part upon analysis of the contextual data; and an output component that provides output sensor data based at least in part upon identification of the degraded sensor data.
