Abstract

Transitory contact of ethanol with the mucous membranes of the mouth or nasal passages, or both is sufficient to drastically alter measurements of concentrations of ethanol in so-called "alveolar" gas for more than 20 minutes after such contract. When true concentrations of blood alcohol were at or clone to zero, readings of greater than 0.40 were obtained on the Breathalyser.
