Blood Alcohol Concentration Factors BAC is the mathematical ti ratio of the percentage of alcohol in the blood stream. Liquor Factors affecting BAC Weight (blood volume) Time Spent Drinking Wine Beer Gender Food Alcohol Content and Size of Drink
100 proof = 50% alcohol Proof = Half.042 % - 12 oz. Beer =.50 oz.045 % - 16 oz. Beer =.72 oz Are all.035 % - 12 oz. Lt Beer =.42 oz 80 proof 1 oz. Whiskey =.40 oz. 80 proof 15oz 1.5 oz. Whiskey=.60 oz..12 % - 5 oz. Wine =.60 oz..077 % - 12 oz Malt Liquor =.92 oz..051 % - 12 oz. Wine Cooler =.61 oz. Are all alcoholic drinks the same? NO, but similar
Are They The Same? Liquor Wine Beer Beer Whiskey Wine Cooler Margarita Myth A DRINK is: a a 12-ounce beer, a 4- to 6-ounce glass of wine, or a shot of liquor. Fact A DRINK is ½ an ounce of alcohol. T 7.7
What two factors are responsible for the differences in alcohol content? The size of the drink Percentage of alcohol in the drink
200 LBS vs. 150 LBS Men & 22oz-200 200 lb Male Women 18oz-200 lb Female 17oz-150150 lb Male 13oz- 150 lb Female
BAC Factors Weight **Heavier people have more blood and other body fluids to dilute alcohol consumed. 0.04 0.08 220 lbs Gender **Their BAC level will be lower than the BAC of a smaller 110 lbs person who drank the same volume of alcohol. Women process alcohol at a slower rate than men. This is because they usually weigh less and produce less of the enzyme dehydrogenase needed by the liver to break down alcohol. *Men also have a higher percentage of body fluids which dilutes the alcohol.
Food Food in your stomach does very little to reduce the effect alcohol has on the brain and liver. However, food coats the lining of the stomach and slows (some) absorption into the blood stream. Note: When alcohol is mixed with carbonated beverages the absorption rate is faster because gases are absorbed faster than liquids. Time Spent Drinking On average, a person s BAC is oxidized at a rate of 0.015 015 per hour 90% of the alcohol detoxified is oxidized (burned up) by the liver 10% is eliminated in breath, urine, and sweat NOTE: Alcohol is toxic to the liver and brain. Hence, the term intoxication denotes the toxic effect alcohol has on these organs.
Elimination Rate Myth The average person can tolerate one drink per hour without t substantial ti impairment. i Facts Sobriety returns ONLY with time. Alcohol is eliminated at approximately.015 BAC per hour. Titanic Principle If you take in more than your system can pump out, sooner or later you ll sink!
} Breath Urine Elimination of Alcohol ELIMINATION PROCESS Sweat} 10% LIVER 90% An adult male with normal liver function eliminates about 0.015015 BAC per hour. Therefore: BAC of 0.05 = 3.5 hours for removal BAC of 0.0707 = 5.0 hours for removal BAC of 0.10 = 7.0 hours for removal BAC of 0.15 = 10.0 hours for removal
Elimination Rate BAC 0.2 0.15 Stops Drinking at 12:30am.16 = BAC Peak at 1 am Still legally INTOXICATED (.08) at 6 am 0.1 0.05 Still IMPAIRED (.05) at 9:30AM 0 9 10 11 12 1 2 3 4 5 6 7 8 9 10 11 12 1 HRS 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 ABSORPTION ELIMINATION
Tolerance Consume more of a drug to reach a given effect. Or body to eliminate the drug faster. Many drinkers develop an ability to mask the effects alcohol has on their brain and body. This ability, however, has NO affect on their intoxication level.
Mood & Alcohol One of two things: Existing mood intensifies (upset to angry) Completely alters mood (happy to mad)
Alcohol affects the heart: Reduces contractibility Increased blood pressure Congestive heart failure
Alcohol affects the stomach Irritates the lining of the stomach Increases acidity Causes ulcers
Alcohol affects the Brain: Kills brain cells Causes memory loss
Attention Reduced ability to comprehend several sources of info at the same time (multi- task) Significant for driving, especially at night
Memory Reduced ability to store and retain info with BAC s as low as.03. Excessive use causes Blackouts
Emotions Emotional control is diminished Honesty Crying Loving g( (I love you, man!)
Aggression Aggressive behavior is enhanced. Especially when combined with competition Deadly when combined with road rage. I bet you cant
Alcohol & Other Drugs Synergistic effect Chemical reaction that produces much greater effect than one drug alone. Can even cause death
BAC Levels Affect the Brain.01 -.05.05 -.10.10 -.20 Reduces Inhibitions Impairs Judgment Gives a False Sense of Confidence Weakens Willpower Slows Reaction Time Reduces Coordination and Balance Affects All Driving Skills Slurred Speech Blurred Vision Impaired Judgment, Memory and Self- Control.20 -.35 Physical Abilities Become Severely Impaired Mental Confusion Unconsciousness, Blackouts or Stupor are Common.35 - higher Subnormal Temperature Little or No Reflexes Breathing May Stop DEATH NOTE: Chugging large amounts of alcohol in a short period of time can result in respiratory paralysis and death.
How does alcohol affect vision? Eye Focus Delayed ability to change focus close to far, the faster the worse. Double Vision impairs ability of eyes to work together. Closing eye would help, but no peripheral vision. Distance Can t do it accurately. Side Vision As alcohol increases, side vision decreases. Night Vision Eyes dilate. Can t control amount of light entering the eyes intensifies glare.
BAC s BAC form.015-.049.049 produce risk taking.03 diminish multitasking 16-19.015 is 2.5 times more likely to be killed 16-19.08 40 times more likely to be killed
Drugs and Driving Perception Judgment Coordination Vision Mood
Marijuana and Driving
Marijuana The active ingredient THC (delta-9- tetrahydrocannabinol) impairs memory and learning perception (sight, sound, time, touch) problem-solving ability motor coordination tracking ability concentration
