Oedema detection

摘要

A method of detecting tissue oedema in a subject. The method includes determining a measured impedance for first and second body segments. An index indicative of a ratio of the extra-cellular to intra-cellular fluid is then calculated for each body segment, with these being used to determine an index ratio based on the index for the first and second body segments. The index ratio can in turn be used to determine the presence, absence or degree of tissue oedema, for example by comparing the index ratio to a reference or previously determined index ratios.

主权项

1. A method of detecting tissue oedema in a subject, the method comprising:
a) determining a measured impedance for a first body segment; b) determining a measured impedance for a second body segment, the second body segment being different from the first body segment; c) for each body segment, and using the respective measured impedance, determining, using a processor of a processing system, an index indicative of a ratio of the extra-cellular to intra-cellular fluid; d) determining, using the processor of the processing system, an index ratio based on the index for the first and second body segments; and e) determining the presence, absence or degree of tissue oedema based on the index ratio.
