Product Datasheet/Brochure

INTRODUCTION
The BACtrack® 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 easy to use; simply
turn on the unit and begin testing in a matter of seconds.
Before you begin testing, please read this 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
