DUI Breathalyzers have little scientific validity
Alcohol
Breath Tests (“ABT’s”) have been in use for over 50 years without a
clear understanding by the general public of the scientifically flawed
theories that they are based on. At the advent of the use of
breathalyzers, or ABTs, the same flawed and invalid theories are still
assumed to be true, despite ample evidence to the contrary by the
world’s leading authorities such has Michael P. Hlastala, M.D., Kurt
Dubowski, Ph.D., and A.W. Jones, Ph.D., among others.
DUI Breathalyzers do not measure air that produces a valid blood alcohol result.
Air
that is measured by the breathalyzer for purposes of testing is the
same air that comes directly from the air that exchanges with the
Alveolar sacs in the lungs. This never happens because it is
biologically impossible, but this is the cornerstone of the junk
science behind the breathalyzer obtaining an accurate BAC. If the air
in the alveoli that exchanges with the blood is not measured, the air
being measured has nothing to do with the blood or the amount of
alcohol in the blood.
The Lung Volume problem
The
ABTs assume that this air is always measured by the breathalyzer after
an individual expels 1.5 Liters of air. This is ridiculous for several
reasons. For starters, lung volume varies by age, size and gender.
Women who tend to be smaller have smaller lungs. A 20 year old male in
perfect health who is 6 feet and four inches tall may have a lung
volume of 6 Liters. A 60 year old female who is 5 feet and 2 inches
tall may have a lung volume as low as 1.5 Liters. She may have even
less volume if she has lung disease or other respiratory conditions
that increase in frequency with the age of the population.
DUI Breathalyzer Airway Sample Contamination
A
second flaw in the “scientific” theory behind breathalyzers is a
complete and utter disregard for the fact that the air tested has to
pass through all the bronchial tubes and the airways before reaching
the mouth and being expelled. The bronchial tubes and airways have a
mixture of water and mucus on their walls. Therefore, when one drinks
alcohol and expels alcohol through their breath, alcohol is deposited
on the walls of their airways. When you blow into the breathalyzer, the
Law Enforcement Officer has you take a deep breath which forces all the
alcohol on the walls of your bronchial tubes and airways out with your
breath sample being tested. This adds alcohol to your sample giving you
a higher and inaccurate BAC result which is drastic, and can be used to
convict an innocent person.
The Cigar Smoker Example
Furthermore,
the bronchial tubes and airways have blood vessels. So, just as when a
cigar smoker feels the nicotine absorbed even though he does not inhale
because of the blood vessels and gas exchange therewith, a person
taking a breathalyzer expels air that exchanges with the blood in the
bronchial tubes and airways and can alter the blood alcohol level and
create evidence of guilt in an innocent person.
Partition Ratio causes inaccuracies in Breathalyzer Results
The
partition ratio is the distribution of equal amounts of alcohol between
blood and air, and is dependent upon temperature, and is known as the
BAC divided by the “blood-breath” ratio between BAC and BrAC. This
ratio has been standardized with an average of 2,100. However, a
variability of up to 40% demonstrated valid concern where those ABT
readings are close to the legal limit and can determine whether an
arrest and conviction may be valid or not.
The current scientific data available displays the flaws in the Junk Science of Breathalyzers
Newer
data over the past 30 years indicates that the previously accepted
model for alcohol exchange has inconsistencies with the idea that that
BrAC is equivalent to alveolar concentration.
