INTRODUCTION
The BACtrack® is an 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 approximately the same amount of alcohol as 1 ml of
blood.
