Abstract
In use of at least two electrode pairs for the generation of a difference signal that corresponds to the flow through a vein upstream and downstream of the connection of a venous duct to the vein, a first signal is generated that corresponds to the resistance over the first electrode pair, upstream of the connection of the venous duct to the vein, a second signal is generated that corresponds to the resistance over the second electrode pair, downstream of the connection of the venous duct to the vein, and the difference signal between the first and the second signal is then determined so that a regional blood flow through a person or an animal can be determined.
