The “breathalyzer” is a test of a person's BAC. (Blood Alcohol Concentration). This is found to be true in many cases of drunk and recless drivers, intoxicated people and others. The breathalyzer is a ture test and is used in many cases.
I believe that it relates to or involves free oxygen, if it is used in exercise- aerobic practices help improve the the efficiency of the body's cardiovascular system with absorbing and transporting oxygen.
Hope this helps
