Comparison of Blood Alcohol Levels with Breath Alcohol Levels Measured Using the Drager 711 MKIII Breathalyzer


Over the past century the breathalyzer has become an indispensable tool for
identifying alcohol levels among drivers. This instrument measures breath alcohol concentrations and is correlated with blood alcohol levels at a 2100:1 partition ratio. Recent uncertainty with this association has resulted in a legal standstill in the conviction of drunk drivers. The study objective was to assess the correlation between breath alcohol, as measured using the Drager 7110 MKIII breathalyzer, and blood alcohol concentrations (BAC).
