Something you need to know firstly


Many people driving home after a night on the town dread the image of a police officer in the rear-view mirror, carrying a small device in his hand. This little device is an alcohol breath analyzer, and has probably saved countless lives since its invention.


Before we get to how breath analyzers work, look at this fact. Of all the road accident deaths in the United States, around 38 percent are because of alcohol. Roadside tests like reciting the alphabet backward, or walking a straight line, are often inconclusive, and a blood test is rarely feasible on the roadside. Here is where a breath analyzer helps; it can easily and quickly measure BAC (Blood Alcohol Concentration) levels, and if needed, the offending driver can be taken off the road. In most states, the permissible BAC level is 0.08.

Breath analyzers work on this principle: When alcohol enters the body, it does not change the chemical composition, but adds to it. What happens is that alcohol is absorbed by the stomach and intestines, and then gets into the bloodstream. It travels around the body with the blood, and eventually enters the lungs. There, alcohol mixes with exhaled air. When exhaled, the ratio of this air to the level in the blood has been shown to be about 2100:1; so, it is easy to calculate how much alcohol you have in your blood by measuring how much is in your breath.
