INTRODUCTION

Your BACtrack Vio is a personal alcohol screening device
used for the detection of alcohol in the breath. It uses an
MicroCheck™ Sensor Technology to analyze your breath,
then transmits this reading to your smartphone or tablet via
Bluetooth, where your Blood Alcohol Content (BAC) estimate is
displayed.

Alcohol and Its Effects on the Human Body

When alcohol is consumed, it is absorbed from the mouth,
throat, stomach, and intestines into the bloodstream. Blood
carries the alcohol throughout the body - including to the
lungs. As alcohol-laden blood moves across the membranes
of the lung’s air sacs (alveoli), it permeates the breath. The
concentration of the alcohol in the alveolar air is directly related
to the concentration of alcohol in the blood.

The ratio of breath alcohol to blood alcohol is generally
estimated to be 2,100:1. Therefore, every 2,100 ml of alveolar
air contains approximately the same amount of alcohol as 1 ml
of blood. The breathalyzer uses this ratio in order to make an
accurate estimate of your BAC.

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 tissues in
your body absorb the alcohol. Your brain is a tissue made up
of a large concentration of fluids and absorbs a large amount
of any alcohol you drink. Your liver eliminates the absorbed
alcohol at its own rate 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.

How does alcohol affect my body?

Alcohol is a depressant. It has a relaxing effect on the muscles
in your body. As the muscles of your eyes relax and lose focus,
your eyesight becomes fuzzy and you may experience double
vision. Brain activity is slowed. Your judgment, reflexes, and
coordination are all negatively affected.

How does alcohol affect my driving?

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 to driving safely. If you jeopardize either one by drinking
and driving, you are likely to be involved in a serious or fatal
collision. You may kill yourself, your best friends, or someone
else’s family

.

DOSE SPECIFIC EFFECTS OF ALCOHOL*

Feeling of well-being, relaxation, lower inhibitions

level of intoxication.

Euphoria. Slight impairment of balance, speech,
vision, reaction time, and hearing. Judgment and
