Detailed Information
A Breath Alcohol Test is a non-invasive diagnostic procedure used to measure the concentration of alcohol in a person's breath, which correlates closely with their blood alcohol content (BAC). This test is commonly employed in clinical, legal, and occupational settings to assess alcohol impairment or monitor abstinence.
How It Works
- When alcohol is consumed, it enters the bloodstream and is carried to the lungs.
- As the blood passes through the pulmonary capillaries, alcohol diffuses into the alveolar air sacs.
- During exhalation, this alcohol vapor is expelled and can be measured using a breathalyzer device.
- The device calculates BAC based on the amount of alcohol detected in the breath sample.
