Can a person's breath really be used to measure blood alcohol level?

Some say no. However, the police administering the breathalyzer are using the machine to determine your blood alcohol by measuring the amount of alcohol in your breath. When alcohol is consumed, it isn't digested right away; a portion of the alcohol you consumed makes it through the lungs. Some of the alcohol you drink passes through the membranes of your lungs and into the actual air. The air in your lungs, therefore, captures a small portion of the alcohol in your body.

When you blow into a breathalyzer, the machine is attempting to calculate the level of alcohol in the breath you expel, to attempt to measure what your actual blood alcohol level is. It has been concluded that the ratio of alcohol in your breath to the alcohol in your blood is 2100 to 1. This means that 2100 milliliters of breath will contain the same amount of alcohol as 1 milliliter of your blood.

By doing the math, the machine spits out a number that attempts to show your actual blood alcohol level. If your blood alcohol level is .08 grams of alcohol for every 100 milliliters of your blood, you may be considered an intoxicated driver by the arresting officer.

If you have been charged with drunk driving, you need an attorney with the right breathalyzer knowledge! Don't feel bad for what happened, discover what you can do about it.
