Introduction - BACtrack ELEMENT Owner's Manual

INTRODUCTION

The BACTRACK Element 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 AAA batteries and is very
easy to use. Simply turn on the unit and begin testing 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 concentra-
tion 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.
