A method of providing blood glucose therapy for a critically ill patient includes calculating a baseline nutrition feed requirement based on an algorithm that incorporates at least one of age, gender, and body size of the patient: determining a first blood glucose level; determining a second blood glucose level after a preselected time interval: determining a first body temperature reading: comparing the blood glucose levels: and administering either nutrition or insulin. The amount of nutrition administered to the patient is based on a first change in blood glucose level, the current body temperature reading, and a predetermined feed algorithm based on the second blood glucose level as well as the baseline nutritional feed requirement. The amount of insulin administered is based on a second change in blood glucose level, body temperature, and a predetermined insulin algorithm that incorporates at least one of the patient's body frame size, age, and gender.

An example system and method of reconstructing cardiac activation information are disclosed. An analysis signal and a reference signal are processed to determine whether there is a first point of change in a first selected-order derivative of the analysis signal with respect to a first selected-order derivative of the reference signal above a first threshold. The analysis signal and the reference signal are processed to determine whether there is a second point of change in a second selected-order derivative of the analysis cardiac signal with respect to a second selected-order derivative of the reference cardiac signal above a second threshold. An activation onset time is assigned in the analysis cardiac signal at a point based on a mathematical association of the first point of change and the second point of change to define cardiac activation indicating a beat in the analysis cardiac signal.

The invention relates to a method for determining the flow or the flow rate of a medium in an electrically conductive object, in particular a pipe (1) or a pipeline, through which a medium flows. At least one ultrasonic wave (16) is produced by means of a transmitting transducer (11) in the object and is injected into the medium as a longitudinal wave (8) on an inner side of the object, and an ultrasonic signal, coming at least partially from the longitudinal wave (8), is received by the receiving transducer (12), at a spatial distance from the injection point and is used to evaluate the flow or the flow rate. Said transmitting transducer (11) produces, preferably in the absence of an acoustic coupling with the surface of the object, a first variable magnetic field in an area close to the surface of the object, in particular metallic, and a first ultrasonic wave is produced in said area by means of the interaction of said variable magnetic field with a static or quasi-static magnetic field. Said transmitting transducer (11) also produces an additional variable magnetic field in the area of the object and an additional ultrasonic wave is produced in said area by means of the interaction of the variable magnetic field with a static or quasi-static magnetic field, said other ultrasonic wave is superimposed on the first ultrasonic wave such that an amplitude of a resulting wave in the direction of the receiving transducer (12) is increased and is reduced in the direction away from said receiving transducer (12). Preferably, the first and the second magnetic fields are produced by two high frequency bobbins (18, 19) of the transmitting transducer (11).
