Track your B.A.C. – BACTRACK!
The BACTRACK® B70 Breathalyzer is a professional alcohol
screening device, used for the detection of alcohol in the breath.
The BACTRACK provides a digital result, indicating the approximate BAC (Blood Alcohol Content) of the test subject. The
BACTRACK is powered by two AA batteries and is very easy to
use. Simply turn on the unit and begin testing your alcohol level
in a matter of seconds. However, before you begin testing, there
are a few things you should know. Please take a moment to
read your owner’s manual in its entirety and familiarize yourself
with the BACTRACK.
Alcohol and Its Effects on the Human Body
Alcohol is absorbed from the mouth, throat, stomach and
intestines into the bloodstream.
Alcohol ingested by the human body can be detected in the
breath because of its presence in the bloodstream.
Alcohol cannot be digested, and it cannot be chemically
changed in the bloodstream. As the blood flows through the
lungs, alcohol in the bloodstream moves across the membranes
of the lung’s air sacs (alveoli) into the air. The concentration of
the alcohol in the alveolar air is directly related to the concentration of the alcohol in the blood. As the alveolar air is exhaled, the
alcohol in it can be detected by the breath alcohol testing device.

The alcohol concentration in the breath is related to that in the
blood, and because of this, an individual’s BAC can be determined by measuring alcohol in the breath. The ratio of breath
alcohol to blood alcohol is generally estimated to be 2,100:1.
Therefore, 2,100 milliliters (ml) of alveolar air will contain approximately the same amount of alcohol as 1 ml of blood.
Alcohol is a Drug
Alcohol is the chemical (ethanol or ethyl alcohol) resulting from
the fermentation of grapes or grain. Alcohol is absorbed directly
into your bloodstream. From your bloodstream, the fluids in your
body tissues absorb the alcohol. Your brain is made up of a
large concentration of fluids and will absorb a large amount of
any alcohol you drink. Your liver eliminates the absorbed alcohol
at its own rate of time and nothing you eat or drink can speed up
the process. Your liver does this by oxidizing the alcohol (converting it into water and carbon dioxide). Coffee, food or any other
“cure” will not sober you up. Only time will do that.
Some vision impairments that occur when you have been
drinking include:
Narrowing of your field of vision•
Reduction in your depth perception•
Decreased ability to see in darkness•
Increased sensitivity to glare and a longer time •
for your eyes to readjust from the glare
Some mental (brain) impairment can occur when you have
been drinking, including:
Reduced awareness of danger•
Becoming overly confident and reckless•
Difficulty in making decisions•
Reduction in balance•
Slowed reflexes•
Impaired judgment•
How does alcohol affect my driving?
How does alcohol affect my body?
Alcohol is a depressant. It has a relaxing effect on the muscles in
your body. The muscles of your eyes relax and lose focus. Your
eyesight will become fuzzy and you may experience double
vision. Brain activity is slowed. Your judgment, reflexes, and
coordination are all negatively affected.
We can’t emphasize enough how dangerous it is for you to
drink and drive. Your vision and your brain are the most important factors in driving safely. If you jeopardize either by drinking,
and then you drive, you are likely to be involved in a serious or
fatal collision.

BAC Dose-Specific Effects
0.02-0.03% Slight euphoria. Loss of shyness. Depressant effects are not apparent. Impairment
possible in some individuals.
0.04-0.06% Feeling of well-being, relaxation, lower
inhibitions and sensation of warmth.
Euphoria. Some minor impairment of reasoning and memory. Lowering of caution.
Driving skills may be impaired at this level
of intoxication.
0.07-0.09% Slight impairment of balance, speech, vision, reaction time, and hearing. Euphoria.
Judgment and self-control are reduced.
Caution, reason and memory are impaired. Driving skills are always impaired
at this level of intoxication and higher.
0.10-0.12% Significant impairment of motor coordination and loss of good judgment. Speech
may be slurred. Balance, vision, reaction time and hearing will be impaired.
Euphoria.
*
BAC Dose-Specific Effects
0.13-0.15% Gross motor impairment and lack of
physical control. Blurred vision and major
loss of balance. Euphoria is reduced and
dysphoria (anxiety, restlessness) is beginning to appear.
0.16-0.20% Dysphoria predominates. Nausea may
appear.
0.25% Needs assistance in walking. Total mental
confusion. Dysphoria with nausea and
some vomiting.
0.30% Loss of consciousness.
0.40% and up Onset of coma. Possible death due to
respiratory arrest**.
* The effects of alcohol intoxication are greatly influenced by individual
variations among users. Some users will be intoxicated at a much lower
BAC than shown above.
**Death can occur at a lower BAC in some individuals.
The generally accepted legal standard for alcohol intoxication in
the United States is 0.08%. However, your driving skills can be
impaired at a level of 0.04% or lower. It is never safe to drink
any amount of alcohol and drive.
