Abstract
Systems for rapid and accurate analyte measurement are described. For example, periodic glucose measurements can be achieved with high accuracy in a critical care environment by drawing blood into a device more than once per hour, analyzing blood (for example using infrared radiation through plasma). Safety and accuracy can be achieved by improved fluid control and avoidance of clotting. Data can be conveyed (e.g., displayed) to a user. A user can be allowed to annotate the data. For example, a touchscreen or other interface can allow addition of notes on a running graph of data, indicating events or other items of interest that may correspond to data readings or to particular times.

5. An analyte detection and treatment dosing system comprising:
-
a fluid transport network configured to provide fluid communication with a body fluid in a patient through a patient end; a body fluid analyzer accessible via the fluid transport network, the body fluid analyzer configured to measure a characteristic of at least one analyte in the body fluid; at least one pump system coupled to the fluid transport network, the pump system having a sampling mode in which the pump system is operable to withdraw a sample of bodily fluid from the patient end and transport said sample of bodily fluid toward the body fluid analyzer, and an infusion mode in which the pump system is operable to transport an infusion fluid to the patient; a processor configured to; determine the concentration of the at least one analyte from the measured characteristic; and predict a value for the concentration of the at least one analyte at a future time; and a user interface configured to display the determined concentration as a graphic icon, a characteristic of the graphic icon being varied based on the predicted value for the concentration of the at least one analyte at a future time. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A method of displaying patient health care data, the method comprising:
-
measuring an analyte level at a current time interval using a patient monitoring system; determining a concentration of the analyte level at the current time interval based on the measured analyte level; calculating a predicted value for the concentration of the analyte level at a future time interval; and displaying the determined concentration of the analyte level as a graphic icon on a display, wherein a characteristic of the graphic icon is varied based on the predicted value for the concentration of the analyte level at a future time interval. - View Dependent Claims (19, 20, 21, 22, 23, 24)
