Alcohol Detection Via Bioimpedance Mesurements (AlkBIS)

October 30, 2013 updated by: RWTH Aachen University

Examination if the bioimpendanz measurement can be used for the determination of the alcohol content in human blood.

Furthermore the blood alcohol content (BAC) will be estimated by an official breathalyzer and one blood test.

Detailed Description

In this clinical trail it will be analyzed, if it is possible to assess the blood alcohol content (BAC) with the bioimpedance devices (SFB7, ImpediMed; Nicomo).

This technology is non-invasive an can be measured by using conductive electrodes, capacitive electrodes or inductive measurement systems.

The BIS-values will be compared with an official breathanalyzer (Alcotest 7110 Evidential MK III, Dräger, Lübeck, Germany).

Furthermore one blood sample will be taken and analyzed with the ADH method as the current gold standard at the end of the trail.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
bioimpedance measurements while trinking alcohol
Bioimpedance spectroscopy (BIS) measurements on 12 healthy subjects were performed while they were drinking alkohol until reaching a BAC of 0.8 ‰.
Device: bioimpedance mesurements
Bioimpedance measurements were conducted with a BIS device (SFB7, ImpediMed, Pinkeba, Australia) covering a frequency range between 5 kHz and 1 MHz and an ICG device (Niccomo, medis, Ilmenau, Germany)

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Bioimpedance measurements
Time Frame: 4 hours
Evaluation if the bioimpedance measurements can be used to verify and quantify the alcohol content in human blood. Bioimpedance measurements will be conducted with the BIS device (SFB7, ImpediMed) covering a frequency range between 5 kHz and 1 MHz and an ICG device (Niccomo,medis) operating at. The whole-body and hand-to-hand bioimpedance will be analyzed. Extracellular resistance (Re), intracellular resistance (Ri) and capacitive effects (Cm) are calculated by using the Cole model Grimnes (2000).
