In terms of alcohol concentration, what is the typical ratio of breath to blood?

The typical ratio of breath to blood concentration of alcohol is approximately 2100 to 1. This means that for every 2100 parts of alcohol in the blood, there is about 1 part of alcohol present in the breath. This ratio is crucial in breath testing for alcohol because it helps accurately estimate blood alcohol concentration (BAC) based on the measurement obtained from breath samples.

Understanding this ratio is essential for interpreting breath test results and ensuring that the readings reflect the actual level of alcohol impairment. It highlights the relationship between the alcohol concentration in a person's breath and their blood, allowing law enforcement and legal authorities to make informed decisions based on the results from breathalyzer devices like the Intoxilyzer 8000.
