A method of performing impedance measurements on a subject. The method includes using a processing system to determine at least one impedance measurement to be performed, and at one electrode arrangement associated with the determined measurement. A representation of the arrangement is displayed so the impedance measurement can be performed once the electrodes have been arranged in accordance with the displayed representation.

Monitoring system

A method for use in determining fluid levels within a subject, the method including, in a processing device, determining at least one impedance value measured for the subject, determining physical dimensions for at least part of at least one segment of the subject, using the physical dimensions to determine a shape factor at least partially indicative of a shape of the at least one segment and calculating a fluid indicator indicative of the fluid levels in the segment at least in part using the at least one impedance value and the shape factor.

Fluid level determination

Impedance measurement system component

A method of determining parameter values used in impedance analysis of a subject. The method includes using a processing system to determine a number of impedance measurements at a corresponding number of frequencies. The impedance measurements are used to determine estimates of parameter values, with the estimates being used to determine theoretical impedance values based on the parameter value estimates. The theoretical impedance values are compared to the measured impedance values to allow a modification direction to be determined for at least one of the parameter value estimates. This is then used to modify at least one parameter value estimate, with the parameter values being determined at least in part from one or more modified parameter value estimates.
