Electro Interstitial Scan (EIS)

How does the EIS work?
A very small and harmless electric current is applied to the body via six surface
electrodes (two are placed on each temple, hand and foot). While the current
source initiates the electric pulse that passes through the body, the voltage
detector recognises and measures it.
As the current encounters impedance or resistance inherent in the body fluids
and tissues, a drop in voltage occurs. This drop provides indirect information
about the physical and chemical properties of the different body compartments.


What does the EIS measure?
Alongside the current, the Eagle Eye indirectly measures the volume of the
body’s interstitial fluid, which is water and solute surrounding cells. That’s
where the method’s name “Electro Interstitial Scan”, in short EIS, derives from.
The volume of the interstitial fluid represents approximately 16% of the body’s
total water. As the volume is closely related to the amount of sodium in the fluid
and the sodium level is linked to various physical parameters (cellular
activities, blood microcirculation, oxygen and pH level, etc.), our TCM experts
take it as a point of reference to collect the relevant body data.
