Manipulation of Breath Alcohol Tests: Can Specific Techniques Alter Blood Alcohol Concentration Readings?

Summary

This is a prospective cohort study. The investigators will enroll 50 healthy volunteers. In a safe environment and after signing informed consent, each participant will consume a standardized alcoholic beverage. Using a Breathalyzer, the subjects BAT will be measured. If the subject's BAT is less than 0.10 +/- 0.005, the subject will drink another alcoholic beverage. This process will continue until the subject's BAT is 0.10 +/- 0.005. The number of alcoholic beverages the subject consumes will be monitored by the observers. When the target BAT is reached, the subjects will manipulate the breathalyzer in various ways and measure their BAT again after each manipulation. In a set order, the subjects will manipulate the breathalyzer by using less than the subject's maximal exhalation effort, placing the breathalyzer at the side of the subject's mouth, hyperventilating (10 rapidly (less than 1 second) and successive breaths prior to using the device), repeating breathalyzer 5 minutes and 10 minutes after hyperventilation and then drinking cold water after the breathalyzer at 10 minutes and repeating the breathalyzer after drinking some cold water. Descriptive statistical analyses as well as Pearson's product moment correlation coefficient will be employed to determine if any statistically significant correlation exists for any of the manipulations.

Medical and Biotech [MESH] Definitions

Method for determining the circulating blood volume by introducing a known quantity of foreign substance into the blood and determining its concentration some minutes later when thorough mixing has occurred. From these two values the blood volume can be calculated by dividing the quantity of injected material by its concentration in the blood at the time of uniform mixing. Generally expressed as cubic centimeters or liters per kilogram of body weight.

The complete summaries of the frequencies of the values or categories of a measurement made on a group of items, a population, or other collection of data. The distribution tells either how many or what proportion of the group was found to have each value (or each range of values) out of all the possible values that the quantitative measure can have.

Substances interfering with the metabolism of ethyl alcohol, causing unpleasant side effects thought to discourage the drinking of alcoholic beverages. Alcohol deterrents are used in the treatment of alcoholism.

A statistical analytic technique used with discrete dependent variables, concerned with separating sets of observed values and allocating new values. It is sometimes used instead of regression analysis.

Standards for limiting worker exposure to airborne contaminants. They are the maximum concentration in air at which it is believed that a particular substance will not produce adverse health effects with repeated daily exposure. It can be a time-weighted average (TLV-TWA), a short-term value (TLV-STEL), or an instantaneous value (TLV-Ceiling). They are expressed either as parts per million (ppm) or milligram per cubic meter (mg/m3).
