What is Ethyl Alcohol?
Also known as ethanol in its purest state is a clear, colorless liquid, which possesses a
pungent odor and produces a burning taste sensation.
What are Congeners?
Compounds or impurities that constitute a very small proportion of the total volume of a

How does the body handle ethanol?
Absorption, Distribution, Elimination
Absorption
The process of moving alcohol from the stomach and upper small intestine to the blood
compartment.
How is ethanol digested by the body?
Not digested but absorbed unchanged
Residual alcohol
Alcohol which remains in the mouth also known as mouth alcohol.
How long does it take for residual alcohol to diminish below significant levels?
15 minutes
Pyloric Sphincter
Muscular ring connecting the base of the stomach with the upper small intestine.
Duodenum
Upper small intestine
What has the most effect on alcohol absorption?
The quantity of food substances ingested with or immediately prior to consumption
How long does it take for complete absorption to occur?
30 to 90 minutes
Distribution
The process of distributing alcohol between blood and all other tissue water
compartments. A naturally occurring dynamic equilibrium created by alcohol's natural
attraction to water.

58%
What percentage of a male's body is made of water?

Elimination
The process of breaking down (live metabolism) or excreting (lung and kidneys) alcohol
by the body.
What percentage of the metabolic processes account for the elimination of
consumed alcohol?
90-95%
What is the rate of oxidation for a general non-alcoholic?
0.0165 per hour
Why is it important to collect a alveolar or deep lung sample when testing?
if that type of sample isn't collected the sample will be diluted with breath of lower
alcohol concentration from the upper respiratory tract.
Henry's Law
at a given temperature, the amount of alcohol in the air is proportional to the amount of
alcohol in the water solution (refers to wet gas breath simulator, not dry gas canister).
