5.3.1.2. Interference Only When ASU is Activated
1. Check all connections to the ASU, and active accessory to look for possible
metal-to-metal sparking.
2. If interference continues when the ASU is activated and while the electrode is
not in contact with the patient, the monitor is responding to radio frequencies.
Some manufacturers offer RF choke filters for use in the monitor leads. These
filters reduce interference while a generator is activated. RF filters minimize the
potential for an electrosurgical burn at the site of the monitor electrode.
3. Check that the ground wires in the operating room are electrically consistent. All
ground wires should go to the same grounded metal with wires that are as short
as possible.
4. If the above steps do not remedy the situation, qualified service personnel should
check the ASU.
5.3.2. Neuromuscular Stimulation
1. Stop the surgery.
2. Check all connections to the ASU and active electrodes to look for a possible metal-
to-metal spark.
3. If no problems are found, the ASU should be checked by qualified service personnel
for abnormal 50/60 Hz AC leakage current.
5.3.3. Pacemaker Interference
1. Check all connections.
2. Always monitor pacemaker patients during surgery.
3. Always keep a defibrillator available during electrosurgery on patients with
pacemakers.
4. Consult the pacemaker manufacturer for specific recommendations.
