Interesting Historical Note:
The terms Breathalyzer ™ and Breathalyser ™ have become synonymous with breath alcohol testing equipment. Both are trademarked names not owned by Intoximeters, Inc. In fact the term Breathalyzer originated from an instrument invented by R.F. Borkenstein that utilized Chemical Oxidation and Photometry to determine alcohol concentration. The instrument was originally introduced in 1954 and was widely utilized for more than 20 years.
|Why Do We Use Breath to Test for Alcohol Concentrations in the Body? |
|Alcohol is a drug that effects the central nervous system. |
Impairment from alcohol poisoning was originally defined by blood alcohol levels. It was observed that most people showed the beginning signs of mental impairment at around 0.05% blood alcohol concentration (BAC). Above this level it has been found that motor functions deteriorate progressively with increased blood alcohol concentrations. For the average person, unconsciousness results by 0.4% BAC. Above 0.5% (BAC), basic body functions such as the breathing or the beating action of the heart can be depressed to the point that death can occur.
