WARNING: RF Current Leakage.
RF current can be discharged unintentionally through
points of contact between patient’s skin, such as their abdomen and arm. This may
result in a patient alternate site burn.
→
Patient skin to skin contact points should be kept dry and/or separated
with dry gauze or dry toweling.
WARNING: Malfunction of Cardiac Pacemaker and Other Active Implants.
Interference produced by the use of electrosurgical devices can cause a pacemaker or
other active implant to enter an asynchronous mode or can block or interfere with the
implant’s effect. Prior to use of the gi4000 ESU on patients with cardiac pacemakers,
consult the pacemaker manufacturer or a cardiac specialist for further information.
WARNING: Leakage Current via Other Medical Electrical Equipment.
If the gi4000
ESU and physiological monitoring equipment are to be simultaneously used on a patient,
ONLY
monitoring systems that incorporate high frequency current-limiting devices (i.e.
ECG monitors whose connecting cables incorporate protective resistors or RF chokes)
are recommended to reduce interference with the monitoring devices.
→
Monitoring electrodes should be placed as far as possible from the surgical
electrodes.
→
Needle monitoring electrodes are
NOT
recommended.
WARNING:
Burn Hazard.
Position the patient monitoring leads in such a way that
contact with the patient or other leads is avoided because the capacitance between the
electrode cable and the patient may result in some local high current densities causing
thermal burns to the patient.
→
Needle monitoring electrodes are not recommended as their small surfaces
allow for high current density.
→
Keep the active electrode at least 15 cm (6 inches) away from any
monitoring electrode.
→
DO NOT
place the active cord or other equipment cables on the patient.
→
DO NOT
allow the monopolar active cord or the cord to the patient
dispersive electrode to lie alongside, or be entwined with, the cables to the
monitoring electrodes.
WARNING:
Interference Hazard. DO NOT
place dispersive electrode cables, active
cords or other electrosurgical accessory cables near cables leading to or from cardiac
or other patient monitoring equipment.
DO NOT
bundle cables or cords with cables or
cords from other electrical equipment as it may result in interference.
WARNING: Capacitive Coupling Hazard.
Wrapping electrosurgical instrument cords
around metal objects can generate currents (capacitive coupling) which may lead to
electrical shock to the patient or user or fire. Route these cords so they are free from
contact with metal objects.
WARNING: Electrical Shock Hazard.
Follow the instructions for use provided with the
electrosurgical accessories for proper connection to the electrosurgical generator. Prior
to use, ensure all accessories are properly connected to their receptacles and that no
metal components of the accessories are exposed as this may result in injury to the
patient or user.
