Breathalyzer Tests are Conducted Using a Datamaster DMT in South Carolina
A breath alcohol testing device (DataMaster DMT) estimates blood alcohol content by calculating the percentage of alcohol exhaled from the lungs.
How Can a Datamaster DMT Measure Blood Alcohol?
The blood releases alcohol through the breath. When you drink alcohol, the body absorbs it quite literally. It saturates tissue lining in the mouth, throat, stomach and intestines, and enters the bloodstream. When that blood circulates through the lungs, alcohol evaporates out through air sacs in the lungs. A breath test measures the alcohol in the breath that is exhaled.
There’s a mathematical relationship between alcohol blood level and alcohol breath level. It was determined that the alcohol measured in the breath can tell you something about the overall alcohol content in the bloodstream. A “universal” relationship was determined between the two levels alcohol concentrations (despite the fact that each person is unique). The golden rule of breath testing says: Every 2,100 ml of air in the lungs (breath to be exhaled) will contain the same amount of alcohol concentration as 1 ml of blood.
A device that can measure alcohol in the breath, can then estimate alcohol in the blood. Breath testing devices use special technology to calculate the amount of air expelled, the amount of alcohol in that air and then calculate a blood alcohol level based on the ratio above. In South Carolina, the only permissible breath testing device is the DataMaster (DMT), which uses infrared technology to measure the alcohol content in the breath.
Are Breath Test Results Admissible in Court?
Results from the Datamaster, DMT, are admissable as evidence in a driving under the influence charge if proper protocol for administering the test was followed, and you were advised of your rights.
