Breathalyzer Validation Study

Overview

The proposed project will test three commercial cellphone breathalyzers against a police grade breathalyzer device.The study will test the accuracy of these smartphone breathalyzers at assessing Breath Alcohol Content (BrAC) against a standard police grade breathalyzer. This study aims to fill the knowledge gap by determining the validity of smartphone paired breathalyzer devices to accurately assess BrAC. Data collection includes collection of BrAC measurements, as well as survey data.

Arms, Groups and Cohorts

  • Experimental: Commercial Smartphone-paired breathalyzers-Set 1
    • All subjects will first be given a priming dose of alcohol containing vodka designed to raise the blood alcohol content based on weight and gender. Blood alcohol content will first be measured with three commercial smartphone-paired breathalyzers: Drivesafe Evoc, Alcohoot, and BacTrack Pro which will be tested in a randomized order and recorded. Participants blood alcohol content will also be measured using the Intoxilyzer 240, a police grade breathalyzer device After the tertiary dose of alcohol, a nurse will perform a blood draw on the participants, which will be used to determine blood alcohol content.
  • Experimental: Commercial Smartphone-paired breathalyzers-Set 2
    • All subjects will first be given a priming dose of alcohol containing vodka designed to raise the blood alcohol content based on weight and gender. Blood alcohol content will first be measured with three commercial smartphone-paired breathalyzers: BACtrack Vio, Drinkmate, and Floome which will be tested in a randomized order and recorded. Participants blood alcohol content will also be measured using the Intoxilyzer 240, a police grade breathalyzer device After the tertiary dose of alcohol, a nurse will perform a blood draw on the participants, which will be used to determine blood alcohol content.

Clinical Trial Outcome Measures

Primary Measures

  • Percentage Alcohol in Breath Variability
    • Time Frame: 8 Hours
    • Difference in Breath Alcohol Concentration (BrAC) from police-grade (Intoxilyzer 240) and consumer smartphone-paired breath testing devices relative to Blood Alcohol Concentration (BAC) measured from blood draw after tertiary dose of alcohol.

Secondary Measures

  • Differences in Readings on Devices for Percentage of Alcohol in Breath
    • Time Frame: 8 Hours
    • Mean difference in percent of blood in breath (BrAC) between the police-grade and personal, commercial breath testing devices
