Intoxilyzer 8000: The More You Blow

Intoxilyzer 8000: The More You Blow

The Intoxilyzer 8000 is Ohio’s breath testing device in DUI cases.  One of the major flaws of the machine is that its testing protocol can result in inflated tests. The more you blow, the higher it goes.

Wondering Should you blow? Attorney explains in this video. 

The protocol for the Intoxilyzer 8000 in Ohio requires that you produce merely 1.1 liters of breath, less than the amount of air required to fill a two liter pop bottle.  The average adult can exhale between three and four liters of air.  If you are unlucky enough to be tested on this machine, the police will urge you to keep blowing your entire breath into the machine. However, such a long breath will artificially increase the apparent amount of alcohol in your breath by skewing the sample toward your “deep lung air,” where the alcohol is more highly concentrated. If you only blow only the required 1.1 liters, you will give an adequate sample, which may be up to 30% less than the sample that the police want you to give. 

The Intoxilyzer 8000 measures how much breath you provide by something called a ‘pressure transducer.’ Instead of directly measuring the volume of your breath by a pressure switch, like the old Intoxilyzer 5000 did, the 8000 indirectly measures breath. Not only is it needlessly complicated, it simply doesn’t work! The flow sensor systems in Florida’s Intoxilyzer 8000’s are so unreliable that FDLE ordered that police STOP KEEPING RECORDS of the system in monthly checks. In 2011, a system-wide check showed that 40% of the machines in Florida couldn’t accurately measure breath volume! (Source). As of this writing, the author knows of no testing in Ohio to determine if this is a problem.  In fact, recent court decisions reveal that precious little (if any) testing has been done by the Ohio Department of Health prior to the implementation of the machine in Ohio.
