How does the Intoxilyzer 9000 handle situations where residual mouth alcohol may be present?

The Intoxilyzer 9000 is designed to provide accurate blood alcohol concentration (BAC) readings and includes specific protocols to address the presence of residual mouth alcohol, which can skew test results. When a subject may have residual alcohol in their mouth from recent consumption, the device incorporates a waiting period before testing. This waiting period allows any residual alcohol to dissipate, ensuring that the results reflect only the alcohol that is vaporized from the lungs during exhalation, rather than alcohol present in the oral cavity.

By implementing this waiting period, the Intoxilyzer 9000 aims to enhance the accuracy of the test results, thereby ensuring a more reliable assessment of an individual's BAC. This aspect of the test protocol is crucial because it helps to eliminate false positives that could occur due to residual alcohol, which would not accurately represent the person's blood alcohol level.
