|Why Do We Use Breath to Test for Alcohol Concentrations in the Body? |
|Alcohol is a drug that affects 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.
