Types Of Breath Tests
Breathalyzer tests can be broadly grouped into different categories including:
- Passive Breathalyzers: Passive alcohol sensors or passive breathalyzers may be attached to a law enforcement officers clipboard or flashlight. This type of test has internal fuel sensors that are designed to detect the presence of alcohol when a motorist exhales. A driver does not actively blow into a passive breathalyzer and this test is considered a preliminary test that can provide a police officer with cause to investigate the motorist more closely and perform other sobriety testing. Passive breathalyzers are not generally used as evidence in a court of law.
- Active Breathalyzers: Active breathalyzers require a driver to blow into a mouthpiece to determine his or her BAC. There are two distinct types of active breathalyzer devices: preliminary breath tests and evidential breath test machines. Both PBTs and evidential breath tests used by law enforcement officers generally utilize different technology than personal active breathalyzer machines that individuals purchase. Breath test machines utilized by individuals generally rely on semiconductor sensors, which less reliable than fuel cell technology or infrared technology used in professional tests.
NHTSA standards apply to both mobile breath tests and to non-mobile breath tests designed for use at a fixed location.
How Accurate Are Breathalyzer Tests And How Do They Measure Breath Alcohol Content
Breathalyzer tests can be relatively accurate if they are used in the appropriate way on the appropriate subject. Testing has been done over the last 30 to 40 years where they have compared breath test results and blood test results. They can often get very close results if somebody was in the right phase of alcohol absorption, if the instrument was used correctly and if the officer had administered the test correctly. A very accurate number might be registered if everything was done correctly, but that would be for an average person blowing through the machine during the post-absorptive phase.

When Is A Breathalyzer Or Intoxilyzer Test Performed
The police will make a breath demand when a person is exhibiting obvious signs of impairment. For example, when a person who is flagged over by a R.I.D.E. program is slurring their speech, there is an odour of alcohol on their breath, they are unsteady on their feet and they are driving badly the police will make a breath demand. In this situation, the police would not have to provide him or her with an approved screening device demand. They would likely immediately arrest the person, based upon reasonable and probable grounds that their ability to operate a motor vehicle is impaired by the previous consumption of alcohol.
Upon arrest, the police officer would then read a formal demand to provide breath samples at the police station. Again, this is a completely different situation from an approved screening device demand. It is not necessary for the police officer to go through the approved screening device demand procedure if they have reasonable and probable grounds that the person is impaired upon observation. Merely exhibiting an odour of alcohol and perhaps bloodshot and glassy eyes would only lead to a suspicion that the person had been drinking and had alcohol in their system It would not lead to reasonable and probable grounds that they are impaired or over the legal limit.

History Of The Breathalyzer
Though the Breathalyzer was not trademarked until 1954, inventive minds were working on the idea of a non-invasive test for determining an individuals level of drunkenness as early as 1874, when Francis E. Anstie learned that tiny amounts of alcohol were produced in a persons breath. In 1927, Emil Bogen wrote a paper on the possibilities of testing for alcohol residue in a persons breath, after conducting a study in which individuals inflated football bladders by mouth to provide a sample for the test.
That same year, a chemist named William Duncan McNally invented a device that detected chemicals in the breath. McNallys device had breath moving through chemicals suspended in water, causing the water to change color. The device was intended for use by housewives to test the drunkenness of their husbands after a night out with the boys.
The first breath analyzer that could practically be used at the roadside, called a drunkometer, was developed in 1931 by Rolla Neil Harger of the Indiana University School of Medicine. This device captured an individuals breath in a balloon inside the machine. The breath sample was then passed through a solution of acidified potassium permanganate, which changed color if there was alcohol in the breath sample.

Why Do I Have To Go To A Police Station For A Breath Test In Oregon
Since small, hand-held breathalyzers are generally unreliable enough to provide evidence in court, in Oregon, those arrested for a DUI are typically brought to the police station to use the larger devices such as the Intoxilyzer 8000. To reduce faulty readings, all breath alcohol testers used by law enforcement in the US must be approved by the Department of Transportations National Highway Traffic Safety Administration. They are also inspected, re-calibrated, and certified several times per year. These machines are different from personal hand-held breathalyzers, and while there are many devices that are available for consumer use, in Oregon, the police standard is the only standard that is considered in court. The Oregon police standard is to use the Intoxilyzer 8000 machine to administer a breath test. Once again, if you blow a .08 or higher, you will be presumed as legally intoxicated.

The Bactrack C6 Smartphone Keychain Breathalyzer Is Smaller Than A Pack Of Gum
Pros: Super compact, convenient, optional smartphone connect, fairly affordable
Cons: Slightly lower accuracy, requires recalibration
Conveniently, the C6 is designed as a keychain, so you’ll always have it on-hand when you’re wondering if you’re ready to leave a dinner party or should hang out for a while longer. Even smaller than the BACtrack Mobile, the C6 also estimates your ZeroLine to tell you how long till you’re likely at 0.00%.
What’s more, it has the ability to connect to your phone in order to store your reading, too. However, on this model, this feature is optional if your phone is dead or you just don’t want to use it, the keychain breathalyzer functions on its own, displaying your BAC reading on its screen.
Also convenient is the fact that the C6 warms up quickly, in just about five seconds. And being one of the cheaper products we tested, it’s good value for the money. The trade-off is that the C6 isn’t quite as accurate as the more professional devices, but the difference is marginal and unlikely to change anything in practice.

Symptoms Of Alcohol Overdose: When To Use Breathalyzer
Alcohol tolerance varies from person to person as some people who drink frequently develop a higher tolerance for alcohol than a person who drinks occasionally. The overdose occurs in 3 stages.
Stage of excitement:
It is the stage when the BAC level is from 0.02-0.07, in this stage, a person becomes overconfident, over-emotional and euphoric.
Stage of Incoordination:
0.08-0.19 BAC level is when the person has blurred vision, uncoordinated movements and is unfit to drive.
Stage of Narcosis:
From 0.19 BAC onwards, the person is severely agitated and anxious. He loses balance and control of the body then after a while loses consciousness and after some time goes into shock if the dose is increased still. After the shock comes the stage of coma.
Infrared Analysis Vs Fuel Cell Technology
Infrared breath tests such as the Intoxilyzer 5000® are a very common type of breath test technology but are not the only type. Fuel cell technology is also frequently utilized to measure an individuals blood alcohol content. The different testing procedures work in different ways. For example:
Infrared Instruments are the most commonly used breath tests because they are stable and reliable and may be automated. The theoretical basis for IR tests are based on the Beer-Lambert Law of Absorption, which demonstrates that molecules absorb electromagnetic radiation at their own specific unique wavelengths. Each molecule has its own infrared fingerprint, including Ethyl Alcohol, which absorbs radiation at wavelengths of approximately 3.0, 3.39, 7.25, 9.18, 9.50 and 11.5. Because no other compound absorbs radiation at all of these wavelengths and only at these wavelengths, a greater absorption of these wavelengths means a higher concentration of alcohol exists. When an IR test is performed, an individual breathes into a sample chamber and an IR energy beam emerges. Energy loss at the appropriate wavelengths is then measured to determine the level of absorption and thus the amount of alcohol that is present. IR tests are generally performed at police stations and are stationary units.

How Do You Use A Breathalyzer
Timing matters, a lot. The manufacturer’s instructions for all the products we tested say to wait about 20 minutes after eating and drinking to use the breathalyzer since it takes time for alcohol to be absorbed into a person’s system after consumption. But because people’s bodies metabolize alcohol at different rates, measuring at 20 minutes isn’t always going to produce the most accurate results. Depending on your physiology, what else you’ve had to eat or drink, and timing, among other factors, your BAC could very well keep increasing even after a 20-minute wait.
“I can’t give you a fixed number , because depending on how much you drank, your alcohol content is going to keep going up,” Sovndal said. “If I drink 5 beers and 2 tequila shots and then measure it, I could still be on the uprise. It might not flatten out for another hour.”
To be safe, measure your levels after 30 minutes and then again after 60. If your BAC is higher at the second reading, wait another 30 minutes before taking another reading.
How Does A Breathalyzer Work
The Intoxilyzer 8000 is designed to analyze breath samples to determine a persons BAC level. If you consent to a breath test in Oregon, the Intoxilyzer 8000 will take two breath samples. Those breath samples are separated by a few minutes. Once you blow and provide a sample for analysis, the machine uses a series of formulas to determine what the BAC of that person would be.

Legal Blood Alcohol Content Levels
The DUI laws of each state vary, though all have agreed on the maximum blood alcohol level considered to be legal. Even if a person does not feel the effects of the alcohol he has been drinking, his blood alcohol content may be over the states legal limit. The legal BAC level is under .08 percent, though a commercial driver may be prosecuted for DUI at a level of .04 percent or higher. A driver under the legal drinking age of 21 years may be charged with DUI for even a minute BAC. Punishment for driving with a BAC over the legal limit varies by state, as well as by the specific circumstances, whether anyone was injured or property damaged, and whether the individual has prior DUI convictions.
