Combination 860 8
Precautions
The therapist must be aware of the following precautions and potential
hazards.
Simultaneous connection of a patient to high frequency surgical equipment
may result in burns at the site of the stimulator electrodes and possible
damage to the stimulator itself.
Operation in close proximity (less than 1 metre) to shortwave or microwave
therapy equipment may produce instability in the stimulator output.
Consideration must be given to the current densities for any electrode used
with the Combination 860 unit. Current densities greater than 2 mA
rms/cm
2
are not recommended because of the risk of burning. All the
standard EMS Physio conductive rubber electrodes may be used up to the
maximum output of the unit without exceeding this figure. When using other
electrodes, the maximum safe output current should be assessed before
use. First estimate the effective contact area of the electrode in square cm,
and then apply the following formula: -
rms output current (mA) = Area of electrode (cm
2
) x 2
The ratio of the rms to the peak current for the different operating modes is
given in the technical specification section of this manual.
The output indication on the LCD shows the peak output voltage or the
peak output current in mA depending upon the selected mode of operation.
When using direct current, extreme care must be taken to ensure the
patient's safety from electrochemical burning. In particular, care must be
taken to avoid uneven pressure on the electrodes causing high local
current density.
Electrodes must not be applied where there are cuts or abrasions.
