The Science Behind BAC and BrACBAC is a standardized measure of alcohol in the bloodstream, while BrAC is the alcohol concentration in the breath. The relationship between these two is based on the fact that the breath contains a specific amount of alcohol that corresponds to the amount in the blood.

The Role of Alcohol in the BodyWhen an individual consumes alcohol, it is absorbed into the bloodstream through the stomach and small intestine. From there, it is distributed throughout the body. As the body metabolizes alcohol, a portion of it is exhaled from the lungs, where it can be detected by breathalyzers.
Example: Alcohol is absorbed into the bloodstream through the stomach and small intestine, which is why breathalyzers can measure it while it is still in the body.

Measuring BrACBreathalyzers measure the BrAC, which is then converted to an estimated BAC. This conversion is based on specific formulas and algorithms, taking into account factors such as body weight, sex, and metabolism. The conversion process ensures that the BAC reading accurately reflects the amount of alcohol in the blood.
Example: A breathalyzer might take a reading of 0.08% BrAC and convert it to an estimated BAC of 0.08%. These conversions are crucial for determining whether someone is over the legal limit.

Legal Implications and Ethical ConsiderationsBreathalyzers play a significant role in legal settings, particularly in DUI enforcement. They are used in sobriety checkpoints and DUI investigations to determine whether an individual is legally sober.
