Foreword
ii EM3 AEM Monitor User’s Guide
Warnings and Cautions
Refer to the manual of your electrosurgical generator (ESU) for applications information
including warnings and precautions regarding its use before proceeding further.
Explosion, Fire, and Shock Hazards
WARNING
Explosion Hazard. Do not use electrosurgery in the presence of flammable anesthetics.
Fire/Explosion Hazard. The following substances will contribute to increased fire and explosion
hazards in the operating room:
Flammable substances (such as alcohol based skin prepping agents and tinctures).
Naturally occurring flammable gases which may accumulate in body cavities such as the bowel.
Oxygen agents (such as nitrous oxide [N2O] atmospheres).
The sparking and heating associated with electrosurgery can provide an ignition source. Observe fire
precautions at all times. When using electrosurgery in the same room with any of these substances or
gases, prevent their accumulation or pooling under surgical drapes, or within the area where
electrosurgery is performed.
Fire Hazard. Do not use extension cords.
Fire Hazard. For continued protection against fire hazard replace fuses only with the same type and
rating.
Fire Hazard. Electrosurgical accessories that are activated or hot from use can cause a fire. Do not
place them near or touching flammable materials (such as gauze or surgical drapes).
Electric Shock Hazard. Connect the monitor power cord to a properly grounded receptacle. Do not use
power strip plug adapters.
Electric Shock Hazard. Ensure that all accessories, cords, and adapters are correctly connected and
that no metal is exposed.
Electric Shock Hazard. Do not connect a wet power cord to the AEM Monitor or to the wall receptacle.
Electric Shock Hazard. Always unplug the AEM Monitor before cleaning.
Electric Shock Hazard. Do not open the AEM Monitor cover.

Foreword
EM3 AEM Monitor User’s Guide iii
General Electrosurgical Hazards
WARNING
Any electrosurgical procedure is safest if moderate control settings are used along with minimum
activation times. Prolonged activations without the electrode in contact with the tissue should be
avoided.
Confirm proper electrosurgical power setting before proceeding with surgery. Use the lowest power
setting that achieves the desired surgical effect.
In order to lessen the possibility of creating unintended burns, activate the electrosurgical generator
only when the active electrode is near or touching the target tissue.
The safe use of monopolar electrosurgery requires proper placement of the patient return electrode.
To avoid electrosurgical burns beneath the patient return electrode, follow all directions on the
product package for proper return electrode placement and use.
In some circumstances, potential exists for alternate site burns at points of skin contact (e.g., between
the arm and the side of the body). This occurs when electrosurgical current seeks a path to the
patient return electrode that includes a skin to skin contact point. Current passing through small skin
to skin contact points is concentrated and may cause a burn. This is true for earth referenced and
isolated output generators.
To reduce the potential for alternate site skin burns, do one or more of the following:
Avoid skin to skin contact points, such as fingers touching leg, when positioning the patient.
Place two to three inches of dry gauze between contact points to ensure that contact does not
occur.
Position the patient return electrode to provide a direct current route between the surgical site and
the return electrode which avoids skin-to-skin contact.
In addition, place patient return electrodes according to the manufacturer’s instructions.
Keep electrical connections dry while in use to prevent potential conduction of High Frequency (HF)
current to the user.
Potentially hazardous conditions may exist when accessories of similar connector types are
intermixed. Be certain that accessories are appropriate for the type of electrosurgical generator
output used and the intended application.
While using electrosurgery, the patient should not be allowed to come into direct contact with
grounded metal objects (e.g., surgical table frame, instrument table, etc.). If this is not possible
during certain procedures (e.g., those in which noninsulated head frames are used), use extreme
caution to maximize patient safety:
Use the lowest power setting that achieves the desired effect.
Place the patient return electrode as close to the surgical site as possible.
Place dry gauze between the patient and the grounded object if possible.
Continually monitor the contact point(s).

Foreword
iv EM3 AEM Monitor User’s Guide
Active Accessories and AEM Monitor
WARNING
These devices have been specifically designed for use in electrosurgery. Do not use for other
procedures.
Do not wrap accessory cords around metal objects. Wrapping cords around metal objects may induce
currents that could lead to shocks, fires, or injury.
The electrode tip may remain hot enough to cause burns after the electrosurgical current is
deactivated.
When not in use, place accessories in a clean, dry, nonconductive and highly visible area not touching
the patient. Inadvertent contact with the patient may result in burns.
Inadvertent activation or movement of the activated electrode tip outside the field of vision may result
in injury to the patient. Use these instruments only under conditions that ensure adequate
visualization.
Localized burns to the patient or physician may come from electrical currents carried through
conductive objects (such as cannulas or scopes). Electrical current may be generated in conductive
objects by direct contact with the active accessory cable being in close proximity to the conductive
object.
Ensure that the insulation of conventional, nonshielded disposable and reusable laparoscopic
instrumentation is intact. Compromised insulation of nonshielded instruments may lead to shocks or
burns to the patient or surgical personnel.
When using laparoscopic instrumentation with metal cannulas, the potential exists for abdominal wall
burns to occur in the event of direct electrode tip contact to the cannula.
Refer to the cannula manufacturer’s instructions before inserting the electrode into the cannula. To
avoid damaging the electrode or injuring the patient, insert and withdraw them carefully.
Inspect cords for breaks, cracks, nicks or other damage before every use. Verify that end of life
indicators are not present. If any of these are present, do not use. Failure to observe this precaution
may result in injury or electrical shock to the patient or operating personnel.
Damaged external insulation on instruments AND incorrect setup of the AEM Monitor may result in a
risk of unintended patient burn. Do not use product having damaged insulation.
When an alert is presented by the AEM Monitor, discontinue use of the electrosurgical current
immediately. Find the cause of the alert and correct it before continuing use.
Damaged internal insulation of the instrument, or loss of shield continuity, may cause AEM Monitor
alarms. For maximum patient safety, discontinue use of the instrument if this occurs.
A single AEM instrument must be the sole conductor of energy to tissue. Do not conduct energy by
touching an AEM instrument to a second instrument contacting tissue. The second device will not be
protected from capacitive coupling and insulation failure.
Good operating room practice suggests that connections of accessories to electrosurgical generators
be made only while the generator is off or in standby mode.
Use the AEM Monitor only if the Power On Self Test (POST) has been properly completed (see
Section 3 for details). Otherwise, AEM functions may not be operative.
CAUTION
Read the instructions, warnings, and cautions provided with the AEM Monitoring System accessories before
using. Their specific instructions are not included in this manual.
AEM Monitoring will not function without the use of a dual pad return electrode and an electrosurgical
generator equipped with contact quality monitoring patient safety technology.
Limit power setting to 80 watts or lower as specified in the power settings tables (see Section 3). Higher
settings may result in spurious insulation failure alarms and/or insulation breakdown. Refer to instrument
instructions for use for other limits.

Introduction
1-2 EM3 AEM Monitor User’s Guide
Active Electrode Monitoring
Active electrode monitoring technology can eliminate the risk of stray electrical energy
caused by insulation failure and capacitive coupling and thus helps to prevent unintended
internal burn injury to the patient. AEM instruments direct electrosurgical energy where the
surgeon desires, while continuously monitoring the current flow to prevent stray
electrosurgical energy from insulation failure or capacitive coupling.
AEM instruments have a patented, multi-layered design with a built-in shield, much like the
third wire ground in standard electrical cords. The shield in these instruments is referenced
back to a monitor at the electrosurgical generator. In the event of a harmful level of stray
electrical energy, the monitor shuts down the power; ensuring patient safety. The AEM
system protects against capacitive coupling by providing a neutral return path for capacitively
coupled electrical current. Capacitively coupled energy is continually drained away from the
instrument and away from the patient through the protective shield built into all AEM
instruments.
Monopolar Electrosurgery
In monopolar electrosurgery, the surgical instrument contains only the active electrode. A
separate return electrode attached to the patient recovers the current that passes through the
patient and returns it safely to the electrosurgical generator.
Monopolar electrosurgery is used for most surgical procedures that require sparking to
tissue, such as those in which tissue must be cut or coagulated over wide areas.
Bipolar Electrosurgery
In bipolar electrosurgery, the surgical instrument includes both electrodes. A patient return
electrode is not used. Current flows between the two electrodes and through the tissue
contacted by the instrument, heating that tissue.
In bipolar electrosurgery, control is needed to ensure the correct degree of heating.

instruments. The test verifies that the AEM instrument’s internal insulation is in good
condition and can be expected to perform without fault conditions during surgery.
1. Apply the return electrode to the patient.
2. Set the electrosurgical generator to “coag spray” or “coag fulgurate” (the highest voltage
mode depending upon the generator) and set the power level to the maximum power per
the previous tables.
3. Next, in the sterile field:
Connect the instrument to the AEM Monitoring System following the setup instructions in this
section.
WARNING
Ensure that the instrument tip does not touch any other object.
Activate the instrument using the foot switch or hand control for approximately 3
seconds.
Verify that the power indicator on the generator illuminates and that there are no AEM
Monitor alarms.
Repeat this test on each AEM instrument.
4. Change the ESU power setting to the desired level.
