( 1 ) Do not apply the electrodes on the swollen, infected or inflamed areas or skin eruptions.
( 2 ) Do not apply the electrodes on inappropriate sites, such as over chest, the head, anterior neck, eyes, mouth and the front of throat.
( 3 ) Do not apply the electrodes on areas of broken or damaged skin, such as open wounds.
( 4 ) Do not apply the electrodes on the skin with diminished sensation because nerve damage is likely to diminish the effectiveness and the patient maybe unaware that high-intensity currents are causing skin irritation.
( 5 ) Stimulation should not be applied across or through the head, directly on the eyes, covering the mouth, on the front of the neck, (especially the carotid sinus), or from electrodes placed on the chest and the upper back or crossing over the heart.
( 6 ) Stimulation should not be applied transthoracically in that the introduction of electrical current into the heart may cause cardiac arrhythmias.
( 7 ) Stimulation should not be applied over the carotid sinus nerves, particularly in patients with a known sensitivity to the cartid sinus reflex.
( 8 ) Never use the device while sleeping.
( 9 ) Contraindications: Patients with pacemakers and cardiovascular problems should not use the device. The device should not be administered over the abdomen or pelvis during pregnancy. Patients with epilepsy should not apply the electrodes to the neck or head. Patients with heart disease, cancer or any other health conditions should not use the device, unless recommended by a medical practitioner.
