INTENDED USE
ADVERSE EFFECTS
•
This device should not be used over the
gonads/testicles or to the developing
fetus.
•
This device should not be used over the
heart.
•
This device should not be used on the
brain.
•
This device should not be used on
ischemic tissues in individuals with
vascular disease where the blood supply
would be unable to follow the increase
in metabolic demand and tissue necrosis
might result.
•
This device should not be used over or
applied to the eyes.
•
This device should not be use on the facial
sinus as this exposes the eyes to the same
hazards.
•
Ultrasound should not be used on
unconscious patients or over anesthetic
areas.
•
On the head or near the pharynx or larynx.
APPLICATOR MOVEMENT OF
ULTRASOUND
If movement of the applicator is too
slow, the patient may feel periosteal pain
characterized by a deep ache or pain. If
motion is too fast, or if the applicator does
not maintain good contact with the skin, the
therapeutic effect of the sound waves will be
reduced and the applicator may overheat.
Potential Adverse Effects of Ultrasound
•
Cataracts
•
Male Sterility
•
Enhanced Drug Activity
•
Thermal Stress
Patient Susceptibility
Some patients are more sensitive to
ultrasound output and may experience
a reaction similar to a heat rash. Be sure
to inspect the treatment area during and
following treatment, and discontinue if
an adverse reaction does occur.
Coupling
Coupling is described as contact between
the applicator and the treatment site and
may be accomplished through the use of
a coupling agent, such as gel or lotion.
Anything used as a coupling agent must
be highly conductive. Air is a very poor
conductor of ultrasonic waves.
DO NOT
use
a conductive medium with an alcohol based
content or that is not approved specifically
for ultrasound conductivity.
Output Mode
Constant Current (C.C.)
Intensity (mA) remains constant regardless
of the changes in resistance of the electrical
circuit. For example, if the resistance to
current flow INCREASES during a treatment,
the voltage will INCREASE to keep the
current at the appropriate level.
Constant Voltage (C.V.)
Voltage (V) remains constant regardless of
the changes in resistance of the electrical
circuit. For example, if the resistance of
current flow increases during a treatment,
the intensity (mA) will DECREASE to ensure
the voltage remains constant.
