Its breath of fresh air.

Breath alcohol level refers to the amount of alcohol vapor in the breath. Alcohol is excreted into the lungs from the blood in a fixed proportion to the amount in the blood. Therefore, measuring breath alcohol gives an indirect, but accurate, measurement of the amount of alcohol in the blood, and the degree of impairment to brain function.
