    enAugust 17, 2010

    Podcast Summary

    • Implications of a Judge's Intoxication and Alcohol-Related Traffic DeathsJudges being intoxicated on the job can lead to dangerous situations, and alcohol consumption caused approximately 37% of traffic-related deaths in 2008, emphasizing the importance of responsible consumption while driving.

      Responsible consumption is important, especially when it comes to driving. The discussion touched on the implications of a judge being intoxicated on the job, leading to potential dangerous situations. Additionally, statistics were shared highlighting the significant number of traffic-related deaths caused by alcohol consumption in 2008, which was approximately 37%. It's crucial to remember that consuming alcohol and then getting behind the wheel can lead to serious consequences for yourself and others. Meanwhile, the Capital One Venture X Card offers travel benefits, and Kroger brand products promise quality at affordable prices.

    • Breathalyzers: Balancing Individual Freedom and Public SafetyBreathalyzers are a non-invasive method for detecting drunk driving, but the legal limit for intoxication is debated, with some advocating for lower limits. Despite complications, they remain crucial for road safety.

      The use of breathalyzers as a method for detecting drunk driving became commonplace due to the privacy concerns surrounding blood and urine tests, as well as the practicality and non-invasive nature of testing a person's breath. However, the legal limit for intoxication has been debated, with some arguing that a lower limit, such as 0.04 or 0.05, would be more effective in preventing impaired driving. The breathalyzer, while advanced, is not without its complications and criticisms, but it remains a crucial tool in law enforcement's arsenal for ensuring road safety. The discussion also touched upon the historical context of alcohol prohibition and the societal acceptance of alcohol consumption. Ultimately, the use of breathalyzers represents a balance between individual freedom and public safety.

    • The first breathalyzer was invented in 1954, marking a major advancement in breath alcohol analysis.The invention of the breathalyzer in 1954 revolutionized DUI enforcement by providing a non-invasive method to measure alcohol content and promote road safety.

      The development and use of breathalyzers, which measure the alcohol content in a person's breath as a reflection of their blood alcohol content, represents a significant commitment by law enforcement to protect individual rights and save lives. The first breathalyzer, invented in 1954 by Dr. Robert Borkenstein, marked a major advancement in the field of breath alcohol analysis. Breathalyzers work on the principle that alcohol is absorbed into the lungs and can be measured in breath, with a predictable ratio of 2100:1 between the amount of alcohol in the breath and the bloodstream. Despite being a step removed from directly measuring blood alcohol content, the existence of breathalyzers underscores the importance of enforcing DUI laws and promoting road safety.

    • Measuring Alcohol Consumption with BreathalyzersBreathalyzers determine BAC by measuring alcohol content in breath using color change reactions or infrared spectroscopy.

      Breathalyzers work by converting alcohol content in breath into a color change reaction, which is then measured using a photocell system and an electric current to determine the degree of alcohol consumption. This information is used to calculate the blood alcohol content, which is displayed as a reading on the device. Additionally, there's another type of breathalyzer called the Intoxilizer, which uses infrared spectroscopy to measure the amount of infrared light absorbed by alcohol molecules, allowing for a direct measurement of the alcohol concentration in the blood.

    • Measuring Blood Alcohol Content with Different DevicesThe Intoxilizer uses infrared light and a filter wheel, while the Alco Sensor uses fuel cell technology to measure blood alcohol content. Intoxilizer is used in law enforcement and Alco Sensor in handheld breathalyzers.

      Both the Intoxilizer and Alco Sensor are complex devices used to measure blood alcohol content, but they operate in different ways. The Intoxilizer uses infrared light and a filter wheel to analyze the alcohol vapor in breath, while the Alco Sensor uses fuel cell technology to chemically react with the alcohol and produce an electrical signal. The Intoxilizer is often used in law enforcement, while the Alco Sensor is commonly found in handheld breathalyzers. Both devices play crucial roles in ensuring public safety by providing accurate and reliable measurements of blood alcohol content.

    • How the Intoxilyzer Measures BACOne drink per hour with water intake can help reduce the risk of impairment and ensure safe driving.

      The Intoxilyzer, a device used to measure blood alcohol content (BAC), functions by allowing the flow of electrons, which increases with the oxidization of alcohol, creating a current that the microprocessor then converts into a BAC reading. However, it's important to note that even one drink can impair driving ability, and the misconception that a certain weight man can consume a specific number of drinks and still not blow a DUI without specifying the time frame or type of drinks is disputable. A safer approach is to consume one drink per hour and drink a glass of water with each alcoholic beverage to dilute the alcohol intake and expel it from the body more frequently. This can potentially help reduce the risk of impairment and ensure safe driving.

    • Factors affecting breathalyzer test resultsBreathalyzer test results can be influenced by factors like breath phase, depth, and rate. Hyperventilating can lower readings, while deep breaths can increase them. However, manipulating results is not advisable and can lead to further consequences.

      The results of a breathalyzer test can be influenced by various factors, including the phase of breath exhaled and the depth and rate of breathing. Hyperventilating before taking a test can lower the reading, while breathing deeply and exhaling from the bottom of the lungs can increase it. However, it's important to note that attempting to manipulate a breathalyzer reading is not advisable, as cops are present during the test and any suspicious behavior could lead to further consequences. Ultimately, the best approach is to not drive under the influence and to be aware of the potential inaccuracies of breathalyzer tests. Additionally, there are no proven methods to significantly alter one's blood alcohol content outside of natural processes such as time and hydration.

    • Understanding Breathalyzers: Measuring Blood Alcohol ContentBreathalyzers are portable devices used to measure BAC, ranging in price and features. Prevention is key: don't drink and drive.

      Breathalyzers are portable devices used to measure blood alcohol content. They can range in price, with more expensive models offering additional features like temperature sensors and fuel cell technology. It's important to note that the best prevention against driving under the influence is to not drink and drive at all.

Lastly, they mentioned a past episode discussing marijuana consumption in Jamaica.

    • Marijuana cultivation in Jamaican communitiesDespite marijuana being illegal but decriminalized, hidden cultivation sites employ creative and dangerous traps to deter raids, benefiting entire neighborhoods.

      In some communities, particularly in Jamaica, marijuana cultivation is deeply ingrained in the culture, often taking place in remote, hidden locations to avoid law enforcement. Growers employ creative and dangerous traps, like hidden water spikes and sharpened sticks, to deter raids. Although marijuana is illegal but decriminalized for domestic use, the influx of cash from these operations benefits entire neighborhoods. Listeners are encouraged to share stories of clever traps or Rube Goldberg-esque devices at stuffpodcast@howstuffworks.com. Additionally, a new social media platform called Zigazoo, designed specifically for kids to share moderated videos, has piqued the interest of a father who previously swore against letting his children use social media.

    It won't happen to me with Pat Dixon

    It won't happen to me with Pat Dixon

    How many times have you said this phrase in your life?
    "It won't happen to me"... until it did.
    On this episode I will be discussing with a very special guest about the impact a car accident can have on those people that are the first to arrive and offer help at the accident scene.
     
    Pat Dixon.. a hero to many, a first responder that is forgotten like so many others will be sharing what he does to heal emotionally.
    He was a paramedic for 30 years and has witnessed more than he ever wanted to, on the front line at work.  From road accidents, to abuse and suicides, he has seen it all.

    He says " the luck of support in the workplace and no education is not fair to the first responders or to their families. It's immoral to not receive the support they need to deal and process wthat they have seen over the years" this is why PTSD was inevitable.

    After 30 years of working as a first responder in paramedics, he decided to step away  and focus on his well being. With the help of his psychologist and occupational therapist, he is now happy,  calm,  and still very passionate about helping others. 
    He has spend countless hours perfecting his presentation called 'Coping  skills for first responders" and he is sharing what he has learned, so everyone can receive the support and help they need.

    If you want to have Pat on your show  or reach out for a future presentation, send me an email at lifesurvivor_podcast@yahoo.com and I will forward your information directly to Pat.
