A transient ischemic attack (TIA), or ministroke, occurs when part of the brain experiences a temporary lack of blood flow. This causes stroke-like symptoms that resolve within 24 hours. Unlike a stroke, a TIA doesnât kill brain tissue or cause permanent disabilities. Since symptoms of a TIA and a stroke are nearly identical, you should seek immediate emergency attention if you experience any symptoms.
Starting from this BAC, your body needs almost 14 hours to completely metabolize the alcohol. Of course to pass the breathalyzer in all 50 states, your BAC needs to be under 0.04. A 0.04 will not get you a DWI (driving while intoxicated), but you can be charged with a DUI (driving under the influence). To legally pass the breathalyzer after 12 beers in three hours, you need a little over 11 hours.
Introduction to How Breathalyzers Work. We hear and read about drivers involved in an accident who are later charged with drunken driving, and usually a news report on the accident will say what the driver's blood alcohol level was and what the legal limit for blood alcohol is.ou have probably heard about the Breathalyzer, but may wonder exactly how a person's breath can show how much that person has had to drink. Â­It is important for public safety that drunken drivers be taken off the roads. Of the 42,000 traffic deaths in the United States in 1999, about 38 percent were related to alcohol.
