breathalyser


breathalyser

A device used to detect alcohol on a suspected drunk driver’s breath.
Principle
The air in the alveoli is in intimate contact with the capillary blood, meaning that the blood alcohol concentration can be closely estimated from concentration of alcohol in the breath. The breath to blood ratio is about 1:2300, with the caveat that breath alcohol concentration rises faster and falls earlier than in venous blood.
