Can a person exceed their true alcohol concentration by blowing into the Intoxilyzer for an extended period?

The Intoxilyzer 8000 is designed to measure a person's blood alcohol concentration (BAC) based on the alcohol present in their breath. When a person exhales into the device, it samples the breath and uses a scientifically established correlation to estimate the BAC.

Breath alcohol concentration has a direct relationship with blood alcohol concentration; therefore, an individual cannot exceed their true alcohol concentration simply by blowing into the device for a longer duration. The Intoxilyzer operates with specific algorithms that ensure that the readings reflect an accurate representation of the alcohol that is present in the body.

If someone were to continuously blow into the device, it would not change the fundamental value of their BAC but could potentially lead to misleading results if the device were not appropriately calibrated or if the sample was contaminated. However, under standard conditions and with a properly functioning Intoxilyzer, the individual’s BAC remains constant, thus affirming that extending the blowing time does not alter the measurement to reflect a falsely elevated alcohol concentration.
