A breathalyzer or breathalyser (a portmanteau of breath and analyzer/analyser) is a device for estimating blood alcohol content (BAC) from a breath sample.Breathalyzer is the brand name for the instrument that tests the alcohol level developed by inventor Robert Frank Borkenstein.It was registered as a trademark on May 13, 1954, but many people use the term to refer to any generic device for estimating blood alcohol content.here the defendant had refused to take a subsequent blood test, the only way the state could prove BAC was by presenting scientific evidence of how alcohol in the breath gets there from alcohol in the blood, along with evidence of how to convert from one to the other.
In a few states, refusal is a separate criminal offense. An officer cannot compel someone to take a breathalyzer test because there is no way to force someone to blow into the machine. There are a few instances where an officer can compel a blood test if the driver refuses. Due to the recent decision in the case of Birchfield v. North Dakota, this requires a court order, e.g. a search or seizure warrant.
