Development and validation of a model to predict blood alcohol concentrations: Updating the NHTSA equation

摘要

Objects: To date, multiple models have been developed to estimate blood or breath alcohol concentration (BAC/BrAC). Several factors have been identified that affect the discrepancy between BACs/BrACs and retrospective estimation (eBAC) with existing equations. To the best of our knowledge, a model to quantify the effects of factors on the discrepancy between BAC/BrAC and eBAC is still nonexistent The goal of this work was to develop a model to provide a more accurate retrospective estimation of breath alcohol concentration (eBAC).
