The blood exchanges gases in the lungs. Oxygen is taken in by the blood from the inhaled air, and the exhaled air contains traces of alcohol that the blood has exchanged with the air that was just inhaled. The Breathalyzer device that the police use can detect the alcohol in the exhaled air.

The alcohol contained in exhaled breath would be gone within an hour and one-half.
Breath alcohol level refers to the amount of alcohol vapor in the breath. Alcohol is excreted into the lungs from the blood in a fixed proportion to the amount in the blood. Therefore, measuring breath alcohol gives an indirect, but accurate, measurement of the amount of alcohol in the blood, and the degree of impairment to brain function.
The chemical formula of exhaled breath is Carbon Dioxide = CO2.
If you hold your breath, the carbon dioxide concentration in the blood will increase. Carbon dioxide is constantly produced by the body's metabolism, and constantly exhaled. So if it is not exhaled, it will start to build up.

No. An alcohol breath test is only an estimate of the actual blood alcohol concentration, which can only be determined by drawing and analyzing a sample of blood.
