The Variability of the Blood/Breath Ratio and Its Impact on the Results of Breath-Alcohol Analyses (Journal Article) Washington DC :American Chemical Society ,2023 4166–4167p. Journal of Chemical Education Volume 100, 2023 - Issue 11, November 2023 ***______{For Hard Copy, Please visit Library.}________*** Abstract: In a recent article ( J. Chem. Educ. 2023, 100 (6), 2166), Carma, Miranda, and Silva say, “the highest probability of the blood/breath ratio [(BBR) which is the proportionality factor that relates blood-alcohol concentration (BAC) to breath-alcohol concentration (BrAC)] is around 1900:1 to 2400:1.” In fact, this ratio varies considerably, which the authors allude to only briefly. The impact of that variability on breath-alcohol analysis results is addressed in this Letter to the Editor.
