Abstract: A medical device placement and monitoring system is provided that includes numerous circuits that can be used alone or in combination. The circuits include a feedback initiator, a feedback receiver, and a clinician notifying device. By various means in the provided circuits, the feedback initiator provides information about the location of a radio frequency identification tag secured to a medical device inserted within a patient. This information or data is received and analyzed by the feedback receiver that monitors the circuit, which then transmits an output to the clinician notifying device to alert or advise the attending clinician of this information. The data that is output supplies information about the location of the radio frequency identification tag to the clinician, thereby assisting the clinician in placement of a variety of medical devices including nasogastric or endotracheal tubes, as well as in monitoring proper device placement after initial insertion.
