DUI
Driving under the influence (DUI)—also called driving while impaired, impaired driving, driving while intoxicated (DWI), drunk driving, operating while intoxicated (OWI), operating under the influence (OUI), operating vehicle under the influence (OVI), and drink-driving (UK/Ireland)—is the offense of driving, operating, or being in control of a vehicle while impaired by alcohol or other drugs (including recreational drugs and those prescribed by physicians), to a level that renders the driver incapable of operating a motor vehicle safely. Terminology The name of the offense varies from jurisdiction to jurisdiction and from legal to colloquial terminology. In the United States, the specific criminal offense is usually called driving under the influence, but states may use other names for the offense including "driving while intoxicated" (DWI), "operating while impaired" (OWI) or "operating while ability impaired", and "operating a vehicle under the influence" (OVI).

Drunk Driver
Drunk driving (or drink-driving in British English) is the act of driving under the influence of alcohol. A small increase in the blood alcohol content increases the relative risk of a motor vehicle crash. In the United States, alcohol is involved in 30% of all traffic fatalities. Effects of alcohol on cognitive processes Alcohol has a very significant effect on the functions of the body which are vital to driving and being able to function. Alcohol is a depressant, which mainly affects the function of the brain. Alcohol first affects the most vital components of the brain and "when the brain cortex is released from its functions of integrating and control, processes related to judgment and behavior occur in a disorganized fashion and the proper operation of behavioral tasks becomes disrupted." Alcohol weakens a variety of skills that are necessary to perform everyday tasks. One of the main effects of alcohol is severely impairing a person's ability to shift attention fro ...

Breathalyzer
A breathalyzer or breathalyser (a portmanteau of ''breath'' and ''analyzer/analyser'') is a device for estimating blood alcohol content (BAC), or to detect viruses or diseases from a breath sample. The name is a genericized trademark of the Breathalyzer brand name of instruments developed by inventor Robert Frank Borkenstein in the 1950s. Origins A 1927 paper produced by Emil Bogen, who collected air in a football bladder and then tested this air for traces of alcohol, discovered that the alcohol content of 2 litres of expired air was a little greater than that of 1 cc of urine. However, research into the possibilities of using breath to test for alcohol in a person's body dates as far back as 1874, when Francis E. Anstie made the observation that small amounts of alcohol were excreted in breath. Also, in 1927 a Chicago chemist, William Duncan McNally, invented a breathalyzer in which the breath moving through chemicals in water would change color. One use for his ...

Blood Alcohol Content
Blood alcohol content (BAC), also called blood alcohol concentration or blood alcohol level, is a measurement of alcohol intoxication used for legal or medical purposes; it is expressed as mass of alcohol per volume or mass of blood. For example, a BAC of 0.10 by (0.10% or one tenth of one percent) means that there is 0.10 g of alcohol for every 100 mL of blood, which is the same as 21.7 mmol/L. A BAC of 0.10 by (0.10%) is 0.10 g of alcohol per 100 g of blood (23 mmol/L). A BAC of 0.0 is sober; in different countries the maximum permitted BAC when driving ranges from about 0.04% to 0.08%; BAC levels over 0.08% are considered very impaired; above 0.4% is potentially fatal. Effects by alcohol level Estimation by intake Blood alcohol content can be estimated by a method developed by Swedish professor in the 1920s: :EBAC = \frac\times100\%-\beta\times T where: * is the mass of alcohol consumed. * is the ratio of body water to total weight.

Cannabis
''Cannabis'' () is a genus of flowering plants in the family Cannabaceae. The number of species within the genus is disputed. Three species may be recognized: ''Cannabis sativa'', '' C. indica'', and '' C. ruderalis''. Alternatively, ''C. ruderalis'' may be included within ''C. sativa'', all three may be treated as subspecies of ''C. sativa'', or ''C. sativa'' may be accepted as a single undivided species. The genus is widely accepted as being indigenous to and originating from Asia. The plant is also known as hemp, although this term is often used to refer only to varieties of ''Cannabis'' cultivated for non-drug use. Cannabis has long been used for hemp fibre, hemp seeds and their oils, hemp leaves for use as vegetables and as juice, medicinal purposes, and as a recreational drug. Industrial hemp products are made from cannabis plants selected to produce an abundance of fibre. Various cannabis strains have been bred, often selectively to pro ...

Robert Frank Borkenstein
Robert Frank Borkenstein (August 31, 1912 – August 10, 2002) was an American inventor, researcher, and professor, and is known as the inventor of the Breathalyzer. Early Years Robert F. Borkenstein was born in Fort Wayne, Indiana on August 31, 1912. He graduated high school during the beginning of the Great Depression, and due to other financial issues and constraints he was unable to continue his education in college. He would find employment working in Fort Wayne as a photographic technician, where he developed an expertise in color film leading to his invention of the color camera. In 1936, because of his skills and creativity Borkenstein was hired by the Indiana State Police Criminology Laboratory. Rising through the ranks quickly, Borkenstein when from working as a clerk to Captain in charge Laboratory Services. Throughout his time with the Indiana State Police, he helped to improve the use of photography in law enforcement and assisted in the creation of the polygraph machi ...

Alcohol Poisoning
Alcohol intoxication, also known as alcohol poisoning, commonly described as drunkenness or inebriation, is the negative behavior and physical effects caused by a recent consumption of alcohol. In addition to the toxicity of ethanol, the main psychoactive component of alcoholic beverages, other physiological symptoms may arise from the activity of acetaldehyde, a metabolite of alcohol. These effects may not arise until hours after ingestion and may contribute to the condition colloquially known as a hangover. Symptoms of intoxication at lower doses may include mild sedation and poor coordination. At higher doses, there may be slurred speech, trouble walking, and vomiting. Extreme doses may result in a respiratory depression, coma, or death. Complications may include seizures, aspiration pneumonia, injuries including suicide, and low blood sugar. Alcohol intoxication can lead to alcohol-related crime with perpetrators more likely to be intoxicated than victims. Alcohol intoxica ...

Coma
A coma is a deep state of prolonged unconsciousness in which a person cannot be awakened, fails to respond normally to painful stimuli, light, or sound, lacks a normal wake-sleep cycle and does not initiate voluntary actions. Coma patients exhibit a complete absence of wakefulness and are unable to consciously feel, speak or move. Comas can be derived by natural causes, or can be medically induced. Clinically, a coma can be defined as the inability consistently to follow a one-step command. It can also be defined as a score of ≤ 8 on the Glasgow Coma Scale (GCS) lasting ≥ 6 hours. For a patient to maintain consciousness, the components of ''wakefulness'' and ''awareness'' must be maintained. Wakefulness describes the quantitative degree of consciousness, whereas awareness relates to the qualitative aspects of the functions mediated by the cortex, including cognitive abilities such as attention, sensory perception, explicit memory, language, the execution of tasks, temporal ...

Respiratory Depression
Hypoventilation (also known as respiratory depression) occurs when ventilation is inadequate (''hypo'' meaning "below") to perform needed respiratory gas exchange. By definition it causes an increased concentration of carbon dioxide (hypercapnia) and respiratory acidosis. Hypoventilation is not synonymous with respiratory arrest, in which breathing ceases entirely and death occurs within minutes due to hypoxia and leads rapidly into complete anoxia, although both are medical emergencies. Hypoventilation can be considered a precursor to hypoxia and its lethality is attributed to hypoxia with carbon dioxide toxicity. Causes Hypoventilation may be caused by: *A medical condition such as stroke affecting the brainstem *Voluntary breath-holding or underbreathing, for example, hypoventilation training or the Buteyko method. *Medication or drugs, typically when taken in accidental or intentional overdose. Opioids and benzodiazepines in particular are known to cause respiratory depress ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anterograde Amnesia
In neurology, anterograde amnesia is the inability to create new memories after the event that caused amnesia, leading to a partial or complete inability to recall the recent past, while long-term memories from before the event remain intact. This is in contrast to retrograde amnesia, where memories created prior to the event are lost while new memories can still be created. Both can occur together in the same patient. To a large degree, anterograde amnesia remains a mysterious ailment because the precise mechanism of storing memories is not yet well understood, although it is known that the regions of the brain involved are certain sites in the temporal cortex, especially in the hippocampus and nearby subcortical regions. Signs and symptoms People with anterograde amnesic syndromes may present with widely varying degrees of forgetfulness. Some with severe cases have a combined form of anterograde and retrograde amnesia, sometimes called global amnesia. In the case of drug-i ...

Stupor
Stupor is the lack of critical mental function and a level of consciousness, in which an affected person is almost entirely unresponsive and responds only to intense stimuli such as pain. The word derives from the Latin '' stupor'' ("numbness, insensibility"). Signs and symptoms Stupor is characterised by impaired reaction to external stimuli. Those in a stuporous state are rigid, mute and only appear to be conscious, as the eyes are open and follow surrounding objects. If not stimulated externally, a patient with stupor will appear to be in a sleepy state most of the time. In some extreme cases of severe depressive disorders the patient can become motionless, lose their appetite and become mute. Short periods of restricted responsivity can be achieved by intense stimulation (e.g. pain, bright light, loud noise, shock). Causes Stupor is associated with infectious diseases, complicated toxic states (e.g. heavy metals), severe hypothermia, mental illnesses (e.g. schizophrenia, majo ...

Sedation
Sedation is the reduction of irritability or agitation by administration of sedative drugs, generally to facilitate a medical procedure or diagnostic procedure. Examples of drugs which can be used for sedation include isoflurane, diethyl ether, propofol, etomidate, ketamine, pentobarbital, lorazepam and midazolam. Medical uses Sedation is typically used in minor surgical procedures such as endoscopy, vasectomy, or dentistry and for reconstructive surgery, some cosmetic surgeries, removal of wisdom teeth, or for high-anxiety patients. Sedation methods in dentistry include inhalation sedation (using nitrous oxide), oral sedation, and intravenous (IV) sedation. Inhalation sedation is also sometimes referred to as ''relative analgesia''. Sedation is also used extensively in the intensive care unit so that patients who are being ventilated tolerate having an endotracheal tube in their trachea. It can also be used during a long term brain EEG to help patient relax. Risks There are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
