3) NMS devices should not be used while driving, operating
machinery or during any other activity in which involuntary muscle
contraction may put the user at undue risk of injury.
4)Stimulation should not be applied over the carotid sinus. Severe
spasm of the laryngeal and/or pharyngeal muscles may occur when
electrodes are placed over the neck or mouth. (These contractions
may be strong enough to close the airway or cause difficulty in
breathing.)
5)Stimulation should not be applied transcerebrally (through the
head).
6) Adequate precaution should be taken when treating patients with
suspected heart problems or epilepsy. Caution should be exercised
in the transthoracic application of EMS devices so that the
introduction of electrical current into the heart does not cause
arrhythmias. Stimulation should not be applied over swollen,
infected, or inflamed areas or skin eruptions, e.g., phlebitis,
thrombophlebitis, varicose veins, etc. Persistent use of stimulation
in the presence of skin irritation may be injurious.
7)The safety of electrical stimulation for use during pregnancy has
not been established.
8)The long-term effects of chronic electrical stimulation are
unknown.
9) EMS devices should be kept out of the reach of children.
10) Simultaneous connection to RF surgery equipment can cause a
burn.
11) Operation near (e.g. 1m) short wave or micro wave therapy
equipment can change the output values of the stimulator.
12) This equipment may be affected by electromagnetic
interference. Also, other electrical equipment in close vicinity may
be affected by the BioStim NMS. If such effects are suspected either
switch off the offending equipment or increase the distance
between the affected equipment and that suspected of causing the
interference or shorten connecting leads.
