One of the many problems with breath machines is that they cannot tell the difference between alcohol coming from the lungs and alcohol which is already in the mouth or throat. This problem is referred to as mouth alcohol, and is particularly troublesome because, believing it to be alcohol from the lungs, the breath machines will incorrectly multiply the detected alcohol by 2100 times (see my earlier post, Breathalyzers — and Why They Don’t Work).

If because of illness, for example, the body temperature is elevated by only 1 degree Centrigrade (1.8 degrees Fahrenheit), the 1:2100 breath-to-blood partition ratio used by breathalyzers will be altered so as to produce a 7 percent higher test result. Higher body temperatures will, of course, result in even greater errors.
