    摘要: Various systems and methods for detecting air in a chamber of an infusion system are disclosed. In one embodiment, a determination is made that air is contained in the chamber on the basis of a change in the average force exerted against the plunger utilizing a derivative spike for event detection and a systematic reduction in the average force to confirm the nature of the change. In another embodiment, a determination is made that the chamber contains air when a difference between the current force profile and a baseline force profile crosses a threshold. In an additional embodiment, a force profile is classified as being an air force profile or a liquid force profile based on extracted features of the force profile.

    摘要: A calling communication unit (210) transmits a dispatch communication request to a communication infrastructure (202). The dispatch communication request includes at least a dispatch identification of a called communication unit (e.g.,216). In response to the dispatch communication request, the communication infrastructure generates an alert message that includes a dispatch identification of the calling communication unit and determines a telephone number associated with the called communication unit. The communication infrastructure then transmits the generated alert message to the called communication unit based on the telephone number associated with the called communication unit.
