The breathalyzer is an ignition interlock used by the authorities for measuring the blood alcohol content (BAC) of a person. This device was originally designed by Smith & Wesson and were once large machines that cost thousands of dollars per unit. Police departments were the only ones with these devices and they were base units at the station which required them to bring subjects back to the station to be tested.
Today hundreds of ignition interlock device manufacturers make small, portable breathalyzer units that much more accurate and cost as little as $20 each. This enables law enforcement officers to give breathalyzer tests out in the field and the average person can easily purchase an interlock device for their own personal use.
In most states you are considered intoxicated if you drive while your BAC level is over 0.08%, however some states have the limit as high as 0.1%. For the average person it takes an hour to process one drink, so if you have 3 drinks putting you over the limit it will take approximately one hour to put you back into the 2 drink range and up to 3 hours to bring your BAC back down to 0.00%.
With regards to IID Los Angeles officials explains that alcohol affects different people in different ways. A person who drinks everyday may be able to function perfectly fine with a BAC of 0.1%, while another person of the exact same age, weight, size, and stomach composition who rarely drinks might be falling all over the place with a BAC of 0.1%. Your BAC level has absolutely nothing to do with your tolerance of alcohol. The BAC level was set to account for the average person, not the person with an insanely high tolerance who drinks a case a night and two on the weekends. So many people are totally shocked to realize how high their BAC is after just a few drinks. You must blow hard to get an accurate reading from a breathalyzer and this test actually measures the alcohol from air exhaled from deep within the lungs and not just from your mouth.
When you drink alcohol the mouth, throat, stomach, and intestines absorb alcohol into the bloodstream. When your blood passes through the lungs’ air sacs, the alcohol moves across them as well, thus the concentration of alcohol in the breath is directly proportional to the concentration of it in the blood. The breath alcohol to blood alcohol ratio is 2,100:1. This means that every 1 ml of blood has the same amount of alcohol in it as 2,100 ml of exhaled breath.
