The alcohol percentage exhaled by the lungs typically ranges from 0.01% to 0.08% of the blood alcohol concentration (BAC) when a person is drinking. This is due to the principle that approximately 1% of the alcohol in the bloodstream is exhaled through the lungs. The precise amount can vary based on several factors, including individual metabolism, the amount of alcohol consumed, and the time elapsed since consumption. Breathalyzers use this principle to estimate BAC based on breath alcohol content.
