Breath analysis is by far the most commonly used method of testing for blood alcohol concentration (BAC) levels in DUI and DWI cases in Maryland. While not as accurate or reliable as blood tests, breathalyzers generally have been regarded as acceptably accurate for use in drunk driving investigations --- if administered properly.
The underlying theory behind virtually all breath test devices is that there is a uniform and standard ration of breath alcohol to blood alcohol in the ratio of 2100 to 1. In reality, this is not always true. In theory, however, 2100 cubic centimeters of exhaled breath may contain the same percent by weight of alcohol as one cubic centimeter of whole blood. This relationship is commonly expressed as the 2100 : 1 ratio and is also variously referred to by the terms "partition ratio", "conversion ratio", and "breath to blood ratio".
As we have proven in defense of our DUI and DWI clients over the years, there are several defenses to breathalyzers and their results. The more complicated the technology, the more sensitive the tests to variations.
