1. A measurement system for performing impedance measurements on a subject, the measurement system comprising:
a plurality of electrodes configured to be placed in contact with skin of the subject, the plurality of electrodes including limb electrodes configured to be placed on limbs of the subject;
a signal generator coupled to at least a first subset of the plurality of electrodes;
a sensor coupled to at least a second subset of the plurality of electrodes;
a first processing system configured to:
generate control signals to cause the signal generator to generate one or more alternating signals which are applied to the subject via the first subset of the plurality of electrodes;
receive an indication of sensed signals through the subject from the sensor; and
wirelessly communicate information relating to the indication of sensed signals to a second processing system after receiving the indication of sensed signals; and,
a housing, the housing comprising at least the signal generator, the sensor, and the first processing system,
wherein the measurement system is configured to determine the impedance measurements at least in part using the sensed signals; and
wherein the second processing system includes a store for storing a plurality of impedance measurement profiles representing impedance measurement procedures, wherein:
each of the plurality of impedance measurement profiles is for measuring a respective one of:
cardiac function;
oedema;
pulmonary oedema; and,
lymphedema; and,
each of the plurality of impedance measurement profiles designating a subset of the indication of sensed signals configured for use by the second processing system to analyse the impedance measurements and derive a unique combination of different impedance parameters,
wherein the second processing system is configured to:
select one of the plurality of impedance measurement profiles from the store; and,
analyse the impedance measurements in accordance with the selected one of the plurality of impedance measurement profiles, using the unique combination of different impedance parameters to thereby measure and record a presence, absence or degree of at least one of:
cardiac function;
oedema;
pulmonary oedema; and,
lymphedema;
where the selection of the one of the impedance measurement profiles and the analysis of the impedance measurements using the subset of the indication of the sensed signals and the derived unique combination of parameters by the second processing system is configured to reduce an amount of processing required by the measurement system.
