OVI & Your Brain: Who Cares About Impairment?

OVI Science

More Faulty OVI Breath Test Assumptions

One of the faulty assumptions underlying OVI evidential breath testing is the assumption that the tests are measuring the ability of alcohol to impair your brain.  They do not.  The breath test for OVI does not care how, or even if, the alcohol is impairing your brain only that it is in your breath via your lungs via your blood.  The machines do not test venous blood but arterial blood utilizing the scientific principle of Henry’s Law.  As alcohol can be at different rates throughout your body, the machine is not measuring impairment.

During peak absorption arterial blood is higher than  venous blood.  Arterial blood travels to the lungs for normal bodily air exchange and comes into contact with the highest level of alcohol concentration thereby resulting in an overstated (disproportionately high) BAC level.  Venous blood  more accurately indicates BAC levels inside the tissues of the brain and is a better indicator of how much the alcohol is impairing your brain function.

When you start looking closely at the built-in assumptions underlying the OVI tests, you begin to see that evidential breath testing is not the whole truth and nothing but the truth.  Like any other evidence offered in the courtroom it should be vigorously cross-examined just like any other witness against you.
