7.1.3Vacuum electrodes
There is a choice of large and small electrodes. The areas of the electrodes correspond to
those of the 4 x 6cm and 6 x 8cm flexible rubber electrodes. The vacuum electrodes are
sufficiently flexible to ensure optimum contact with the skin, but rigid enough to prevent any
changes in the contour of the part being treated, allowing full advantage to be taken of the
massage effect of the pulsed vacuum.
Keep the sponge pads well moistened during treatment.
After use clean the sponge pads as described in the User Maintenance instructions.
7.1.4 Self-adhesive electrodes
Self-adhesive electrodes have higher series impedance than flexible rubber electrodes. This
can cause the stimulator to terminate treatment at higher current amplitudes. When this
occurs it is recommended to continue the treatment with flexible rubber electrodes, com-
bined with properly moistened sponge pads.
Self-adhesive electrodes are not recommended for use with currents that contain a DC com-
ponent.
CAUTION:
Do not use electrodes on open wounds.
7.1.5 Electrolytic effects
Electrolysis occurs under the electrodes when current types with a DC component are
applied. Because the largest concentration of electrolytic by-products caused by ion migra-
tion occur under the electrodes, we recommend the use of the supplied sponges to keep the
effects to a minimum. Make sure that the sponges are kept well moistened and place the
thick side of the sponge between the flexible rubber electrode and the patient.
7.1.6 Current density
In the particular standard for Electrical Nerve and Muscle Stimulators, IEC 60601-2-10, it is
recommended not to exceed a current density of 2 mA r.m.s. / cm², otherwise skin irritations
or burns can occur. For current types that contain a DC component we recommend not to
