• Under extreme conditions it may be possible that the mute sensor, pre-amplifier
or the stimulator pod are affected by RF. In this case, the offending piece of
equipment should be identified and replaced. Alternatively, an improvement may
be achieved by moving the pre-amplifier, stimulating pod, associated cables, or
changing the position of the mute sensor.
• Incorrect needle placement or faulty electro-surgical equipment has the potential
to cause burns at the point of contact between the needle electrodes and tissue.
It is therefore strongly recommended that instructions are strictly adhered to, and
that the equipment is regularly checked and serviced.
• The possible risk of burns caused by interaction between the electrosurgical
machine and the monitor should be a factor in balancing the risks associated
with the surgery.
• In order to reduce possible induced current in needle electrode leads (caused by
stray RF emitted by the electro-surgical unit), the electrode leads should be kept
as far as possible from the electro-surgical unit.
• Cables from the electro-surgical unit, both active and return, should also be kept
as far as possible from the electrode leads.
• Patients with active medical devices, such as pacemakers or cochlear implants,
should not be stimulated using the stimulating probe without due consideration
being given to the risks involved. Current must not pass across the heart or the
implanted device. The use of bipolar probes will greatly reduce any possible current
spread. If used, keep the current to the minimum needed to stimulate the nerve.
• Leads or equipment which do not comply with IEC 60601-1 should not be
connected to the nerve monitor (and accessories), or plugged into the connection
sockets.
• Only the supplied AC power lead should be connected to the nerve monitor. If
required, replacement/s can be obtained via the sales department.
• The nerve monitor must not be used in the vicinity of objects sensitive to magnetic
fields.
• Neurosign
®
stimulating probes have been specifically designed to limit the current
density at the tips. Do not use non-Neurosign
®
devices as these may not comply
with the current density limits.
• Wireless/Bluetooth export is not intended to be used when monitoring mode is
active
• It is the responsibility of the user to identify, analyse, evaluate and control potential
risks every time a device is connected or disconnected.
• DO NOT step on the device.
• DO NOT sit on the device.
• The maximum load permitted on the device is 1.5kg and should not be exceeded.
