The Breath Flow Curve during the test should indicate which kind of line?

During a breath test administered by the Intoxilyzer 9000, the Breath Flow Curve is used to analyze the quality of the breath sample being provided. The ideal Breath Flow Curve should indicate a smooth and continuous exhalation, which is represented by a thinner line. This thinner line reflects a consistent and appropriate airflow, characteristic of a proper test sample, allowing for accurate measurement of blood alcohol concentration.

In contrast, variations that result in a thicker line may indicate issues such as irregular breathing patterns or a compromised sample. This can lead to erroneous results or the rejection of the sample due to the variability in breathing efforts. Therefore, the correct depiction in the Breath Flow Curve is indicated by the thinner line, ensuring that the breath sample collected is suitable for accurate analysis.
