False High Reading on Infrared Breath Testing Devices.

A study conducted in 1998 added information to the question of alveolar exchange alteration. T. Martinez and R. Martinez, The Effect of an Inhalation Aerosol Bronchodilator on Breathalyzer Results in Drinking and Non-Drinking Subjects, Proc.West.Pharmacol.Soc. 41:51-52 (1998). Is there a difference of false positives between non-drinking and drinking subjects? The researchers found in non-drinking subjects that a single puff from a bronchial inhalator obtained readings as high as 0.120 BrAC in 30 minutes and the subjects returned to a 0.00 BrAC in 6 minutes. Thus, a 20-minute deprivation period should be sufficient for these subjects. However, when drinking subjects who started with a BrAC of 0.05 u


Especially if You Have Had Something to Drink and are Close to the Legal Limit.

However, when drinking subjects who started with a BrAC of 0.05 used a bronchial inhalator, the effects of erroneously high readings were observed over prolonged periods. The influence of the bronchial inhalator influenced the third digit after the 20-minute period. The findings are relevant for testing subjects near the legal limit range; however, the defense for extremely high readings over the legal limit is not supported. Limitations of the study include (1) consideration of oxidization values, (2) that no more than two puffs of a bronchial inhaler were examined, (3) a non-representative population sample, and (4) the limited types of medications available.
