Question : Does hyperventilation just prior to breath tester use reduce the alcohol reading?
I had a lecturer that once said alcohol takes 15 minutes to diffuse to maximal levels in the lungs after hyperventilation. I was wondering if there are any sources where this has been proven. Ive heard Myth Buster may have tested some ideas but couldn’t find any to work. I have some anecdotal evidence from friends who have been clearly over 0.05 but have blown under this limit from prior hyperventilating but this doesn’t convince me.
This is not a question about ethics, its of biological and social interest.

the problem with anecdotal evidence is that there is no control, there is no limits on what other things could be effecting the test results. lets say in a panic your friend starts doing every folk tail he can remember when it comes to beating the test, how are we to know which one of those things did the trick? worse yet how do we know that the result isn’t based on some form of equipment error?

and frankly these laws about drunk driving exist for a reason. how many people go through life thinking they will get cancer? how many people will decide to drive while drunk thinking that they will get into an accident? arrogance is not a variable in physics or chemistry
