Cold injury
This document discusses cold injuries that can occur from exposure to extreme cold, including hypothermia, frostbite, chilblains, dehydration, carbon monoxide poisoning, and snow blindness. It defines each injury, describes symptoms, treatment, prevention, and nursing considerations. The main cold injuries discussed are hypothermia, which lowers core body temperature, and frostbite, which is the freezing of body tissue that can lead to loss of fingers, toes, or other body parts if not promptly treated. Prevention is key and includes proper clothing, limiting time in extreme cold, staying dry and hydrated.
FROSBITE
Frostbite refers to skin and tissue damage caused by freezing temperatures below -0.55°C. It is most common in people spending long periods outdoors, the very young/old, and those with circulation problems or taking medications that constrict blood vessels. When exposed to cold, the body prioritizes core warmth by constricting blood vessels in the extremities, causing them to freeze. Frostbite symptoms range from numbness to blistering and blackened skin depending on severity. Immediate first aid includes slowly rewarming the affected area and seeking medical help to assess damage and prevent complications like infection or tissue death.
Heat stroke - medical information (prevn, treat,etc)
Heatstroke is a condition caused by your body overheating, usually as a result of prolonged exposure to or physical exertion in high temperatures. This most serious form of heat injury, heatstroke, can occur if your body temperature rises to 104 F (40 C) or higher. The condition is most common in the summer months. this slideshare is all about prevention , treatment , causes & all about heat stroke .

Heat-related illnesses range from mild to life-threatening. Heat stroke is the most severe form and occurs when the core body temperature rises above 40.5°C. It can cause damage to the central nervous system and other organs. Immediate cooling through methods like ice packs and cold water is critical for survival, as mortality from heat stroke can be as high as 70% without prompt treatment. Factors like extreme heat, strenuous physical activity, age, and medical conditions increase the risk of developing heat stroke.
Frost bite
Frostbite occurs when body tissues freeze due to prolonged exposure to cold temperatures, most commonly affecting the extremities. Superficial frostbite involves freezing of the skin and subcutaneous tissues, appearing waxy white and numb, while deep frostbite extends to muscles, tendons and bones. Risk factors include alcohol use, age, medical conditions, weather, injury and constrictive clothing. Symptoms may include pins and needles sensation, numbness, hard and pale skin, blisters and blackened skin. Treatment focuses on slowly rewarming the affected areas and preventing refreezing, along with pain medications, antibiotics and tetanus shots as needed. Surgery may be required for severe cases involving tissue death or
Heat stroke
Heat stroke is an acute medical emergency caused by the body's inability to regulate temperature, usually occurring during heat waves accompanied by high humidity. Symptoms include confusion, high body temperature over 105°F, dry hot skin, absence of sweating, fast breathing, low blood pressure, and fast heart rate. Most deaths from heat stroke are in the elderly. Treatment focuses on rapidly reducing the person's temperature to 102°F using methods like cool baths, sheets, and fans while closely monitoring their vital signs. Patients must avoid immediate reexposure to heat and are advised on preventing future heat stroke through hydration, loose clothing, and limiting activity in hot weather.

Frostbite treatment involves gently warming affected areas and seeking medical help.
Frost bite usha
This document discusses frostbite, including its causes, symptoms, classification, treatment, and prevention. Frostbite occurs when skin and underlying tissues are exposed to subfreezing temperatures, causing damage from ice crystal formation and reduced blood flow. It most commonly affects the hands, feet, ears and face. Treatment involves rapid rewarming in warm water followed by wound care. Frostbite severity is classified into four stages based on depth of tissue damage. Prevention focuses on proper clothing, avoiding dehydration/exhaustion, and limiting time in extreme cold or wet conditions.
Burns scalds
Dry heat sources like fire, hot objects, the sun, chemicals and electricity as well as wet heat sources like hot liquids and steam can cause burns and scalds. First degree burns damage only the outer layer of skin and appear as redness and inflammation while second degree burns blister and damage deeper layers of skin. Third degree burns severely damage or destroy skin and can damage deeper tissues, posing a serious risk of infection. For burns and scalds, it is important to run the affected area under cold water for 10 minutes or more, remove jewelry, avoid removing clothing stuck to the burn, apply a sterile dressing, and seek prompt medical attention for anything more than a minor burn or scald.

Wounds and Bleeding
The document discusses wounds, bleeding, and first aid treatment. It defines open and closed wounds and their characteristics. It describes how to treat amputations and severed body parts. The objectives of wound care are to control bleeding and prevent infection through cleaning and dressing. Signs of bleeding include rapid pulse and pale skin. Methods to control bleeding include applying direct pressure, elevation, and pressure points. Proper care includes washing, cleaning, dressing, and bandaging wounds while maintaining pressure and circulation.
Types of bleeding ppt
There are three main types of bleeding: arterial, venous, and capillary. Arterial bleeding is the most severe as blood spurts from damaged arteries in time with heartbeats. Venous bleeding is also serious as veins carry a high blood volume, though blood flows consistently rather than spurting. Capillary bleeding is the least serious as blood trickles from capillaries before stopping. First aid treatments involve applying direct pressure with dressings or bandages to control bleeding from arteries, veins, or capillaries.

Burns Ppt Sept 2006
The document discusses different types of burn injuries including thermal, chemical, smoke inhalation, and electrical burns. It describes the pathophysiology and clinical manifestations in the emergent and acute phases after a burn. Key aspects are fluid and electrolyte shifts leading to shock in the emergent phase and wound healing through debridement, grafting, and rehabilitation in the acute phase. Complications include infection and contractures.
Burns first aid
This document provides information on first aid for different types of burns. It describes first, second, and third degree burns based on depth of skin damage. For minor first and second degree burns, it recommends cooling the burned area with cold water, not breaking blisters, and seeking medical help for more serious burns or if signs of infection appear. For chemical or electrical burns, it stresses immediately flushing the affected area with water for 15-20 minutes and seeking prompt medical care for eye injuries or extensive skin exposure.
Controlling External Bleeding
This document discusses different types of open wounds such as incisions, lacerations, abrasions, puncture wounds, and penetration wounds. It also discusses different types of dressings used to treat wounds including sterile, bulky, and occlusive dressings. The document outlines the steps to control external bleeding which include applying direct pressure to the wound, elevating the wound above the level of the heart, applying a dressing, and monitoring the patient. It also discusses using pressure points and a tourniquet to control severe bleeding.
What is burn and scalds
Burns and scalds are injuries caused by heat from hot liquids, surfaces, or vapors. They range from minor first-degree burns affecting just the outer skin layer to severe third-degree burns penetrating all skin layers. Treatment depends on burn severity but generally involves cooling the burn, applying antibiotic ointment or sterile dressings, and taking pain medication. More serious burns require medical care to prevent infection and promote proper healing. Sunburn is also a type of burn caused by overexposure to UV rays from the sun and should be treated by hydrating skin and protecting it from further sun exposure.
First ai d 4 burn
This document provides information on first aid for burn injuries. It describes the causes and degrees of burns, as well as how to assess the severity. For minor burns, it recommends cooling the affected area with water or other cold liquids for 10 minutes. For more severe burns, it says to protect the burned area and seek immediate medical help. First aid involves removing constricting clothing and jewelry near the burn, cleaning and dressing the wound but not applying any creams or ointments. Special precautions are outlined for burns in the mouth, eyes, and those caused by electricity.
Cold Injuries
Frostbite and immersion foot are cold injuries caused by prolonged exposure to wet and cold conditions. Frostbite results from actual freezing of tissue and causes numbness, pain, blistering and tissue death. Treatment involves rapid rewarming in warm water followed by pain medication and wound care. Immersion foot occurs in wet, non-freezing environments and causes swelling, blistering and nerve damage. Prevention of both injuries focuses on keeping skin dry and body insulated through proper clothing, activity, hydration and avoiding nicotine use.
Burn And Scald
Burn and scald injuries can be caused by heat, electricity, chemicals, or radiation. Thermal burns are the most common and are classified as superficial, partial thickness, or full thickness depending on the depth of tissue damage. A severe burn over 25% of the total body surface area can cause systemic effects like shock due to fluid loss, decreased blood pressure, and increased heart rate. Complications include infection, respiratory failure, renal failure, and contractures. The severity of the burn is estimated using methods like the Rule of Nines or Lund and Browder chart which divide the body into sections and assign a percentage of total body surface area to each.
Heat related illness
This document outlines guidelines for working in hot conditions and preventing heat-related illnesses. It discusses taking regular breaks, drinking plenty of water, and adding salt to meals in summer. Risk factors for heat illnesses include high temperatures, humidity, medical conditions, and dehydration. Heat exhaustion involves symptoms like fatigue, dizziness, and nausea. Heat stroke is a medical emergency defined by a temperature over 40.6°C and may involve confusion, seizures and unconsciousness. Immediate treatment for heat stroke includes cooling the body and seeking medical help.
The Killer Tan: Dangers of Tanning
Tanning used to be perceived as healthy, fashionable and luxurious. However, there is no such thing as a safe tan. In fact, when your skin changes color your cells are actually becoming damaged. Melanoma, the most deadly form of skin cancer, is a disease that affects a younger population and is the second most common form of cancer among teens and young adults ages 15-29. While more are beginning to understand the dangers of tanning, melanoma figures continue to climb.

Lice Aren’t Nice: A Panic Free Guide to Dealing with Lice
Contracting head lice may be a rite of passage for many young students, as relatively few kids finish their elementary years without being affected due to the nature of lice and how they spread. Lice have basically been living on and around humans since the beginning of time. They are so ingrained in human history that the everyday expressions such as “lousy”, “nit-picking”, and “going over something with a fine-toothed comb” all stem from lice infestations!
Contrary to popular belief, contracting head lice does not indicate that a person is in any way unhygienic or unclean.
Read more about lice, how it spreads, how to avoid infestation and what you can do if your child comes home with lice.

Moving Frostbite to Physically Based Rendering
Course presentation at SIGGRAPH 2014 by Charles de Rousiers and Sébastian Lagarde at Electronic Arts about transitioning the Frostbite game engine to physically-based rendering.
Make sure to check out the 118 page course notes on: http://www.frostbite.com/2014/11/moving-frostbite-to-pbr/
During the last few months, we have revisited the concept of image quality in Frostbite. The core of our approach was to be as close as possible to a cinematic look. We used the concept of reference to evaluate the accuracy of produced images. Physically based rendering (PBR) was the natural way to achieve this. This talk covers all the different steps needed to switch a production engine to PBR, including the small details often bypass in the literature.
The state of the art of real-time PBR techniques allowed us to achieve good overall results but not without production issues. We present some techniques for improving convolution time for image based reflection, proper ambient occlusion handling, and coherent lighting units which are mandatory for level editing.
Moreover, we have managed to reduce the quality gap, highlighted by our systematic reference comparison, in particular related to rough material handling, glossy screen space reflection, and area lighting.
The technical part of PBR is crucial for achieving good results, but represents only the top of the iceberg. Frostbite has become the de facto high-end game engine within Electronic Arts and is now used by a large amount of game teams. Moving all these game teams from “old fashion” lighting to PBR has required a lot of education, which have been done in parallel of the technical development. We have provided editing and validation tools to help the transition of art production. In addition, we have built a flexible material parametrisation framework to adapt to the various authoring tools and game teams’ requirements.
High Dynamic Range color grading and display in Frostbite
This talk presents the approach Frostbite took to add support for HDR displays. It will summarize Frostbite's previous post processing pipeline and what the issues were. Attendees will learn the decisions made to fix these issues, improve the color grading workflow and support high quality HDR and SDR output. This session will detail the display mapping used to implement the"grade once, output many" approach to targeting any display and why an ad-hoc approach as opposed to filmic tone mapping was chosen. Frostbite retained 3D LUT-based grading flexibility and the accuracy differences of computing these in decorrelated color spaces will be shown. This session will also include the main issues found on early adopter games, differences between HDR standards, optimizations to achieve performance parity with the legacy path and why supporting HDR can also improve the SDR version.
Takeaway
Attendees will learn how and why Frostbite chose to support High Dynamic Range [HDR] displays. They will understand the issues faced and how these were resolved. This talk will be useful for those still to support HDR and provide discussion points for those who already do.
Intended Audience
The intended audience is primarily rendering engineers, technical artists and artists; specifically those who focus on grading and lighting and those interested in HDR displays. Ideally attendees will be familiar with color grading and tonemapping.
Battlefield 4 + Frostbite + Mantle

NIOSH Fast Facts: Protecting Yourself from Cold Stress
Workers exposed to extreme cold are at risk of cold stress, which can cause hypothermia, frostbite, trench foot, and chilblains. Hypothermia occurs when prolonged exposure to cold causes the body to use up its stored energy and can no longer produce heat. Its early symptoms include shivering and loss of coordination, and its late symptoms include blue skin and loss of consciousness. First aid involves warming the body core and seeking immediate medical help. Frostbite causes freezing injury, especially to exposed areas like fingers and toes. Its symptoms include numbness, pain, and bluish skin. First aid is to slowly warm the affected areas. Trench foot results from prolonged exposure to wet and cold conditions
Working Safely in Cold Weather
Workers exposed to extremely cold conditions are at risk of serious health problems, including hypothermia, frostbite, dehydration and muscle injuries. Frigid temperatures can also cause additional pain for those who suffer from arthritis and rheumatism…
FROSTBITE
Frostbite occurs when body tissues freeze due to prolonged exposure to cold temperatures, most commonly affecting the extremities. Superficial frostbite involves freezing of the skin and subcutaneous tissues, appearing waxy white and numb, while deep frostbite extends to muscles, tendons and bones. Risk factors include alcohol intoxication, old or young age, pre-existing medical conditions, and activities in cold or wet weather. Symptoms range from initial numbness to pain, blistering and blackened skin as tissues die. Treatment focuses on rapidly rewarming the affected areas and preventing refreezing, along with pain medications and wound care if tissue damage occurs.

Actinic keratoses are rough, scaly skin lesions that are precancerous and caused by sun exposure. They most often appear on areas like the face, ears, scalp, and forearms. While they may develop into squamous cell carcinoma, treatments like cryosurgery, chemotherapy creams, and photodynamic therapy can destroy the abnormal cells. Preventing sun damage through sunscreen and protective clothing is the best way to avoid developing actinic keratoses.
Melanoma: Signs & Symptoms
Melanoma is a type of skin cancer that occurs in melanocytes. It most commonly appears on areas of the skin that are not often exposed to sun. Early detection of melanoma through monthly skin self-examinations is important, as it can be fatal if left untreated but curable if caught early. Some warning signs of melanoma include new or changing moles, moles that are asymmetrical, have irregular borders or varied color, or a diameter larger than a pencil eraser.

Cold Hard Facts About Frostbite
- 2. what is frostbite?Frostbite occurs when the skin, and sometimes tissue beneath the skin, freezes due to prolonged exposure to cold temperatures. Frostbite is a skin burn from the cold. Just like a burn from heat, burns are rated by severity and have first, second and third degree forms. Frostnip is the mildest form of frostbite.
- 3. temperature vs. wind chill factorWhile the temperature outside may be cold, you need to consider the wind chill factor. Wind chill is how the outside temperature and wind feel on your skin and can significantly lower the outside temperature depending on wind speed. bundle up & protect your skin!
- 4. wind chill factor -15°F -20°F -25°F time for frostbite to occur 40 minutes 30 minutes 20 minutes
- 5. areas most affected by frostbite ears cheeks chin fingers toes nose Frostbite causes a loss of feeling and color in the affected area. In severe cases, frostbite can lead to amputation.
- 6. layer 2 The next layer should be wool or fleece which are good insulators. wear loose, light layers to trap warm air & keep clothing dry layer 1 Wear a synthetic material that wicks moisture away from the body. outer layer Top layer should be windproof and waterproof. tips to prevent frostbite
- 7. feet & toesChoose waterproof & insulated boots or shoes. headWear a hat. 40% of body heat can be lost from your head. Face masks or scarves also help to protect your mouth & lungs from extreme cold. handsGenerally mittens are warmer than gloves. Make sure they are snug at the wrist.
- 8. limit your time outsideTry to move into warm locations periodically and limit your outside time on extremely cold days. If you have to be outside, move around. Physical activity raises body temperature.
- 9. If you are touching wet snow, wear waterproof apparel from mittens to snow pants. Also make sure that coat sleeves and pants are tight at the wrist and ankles to keep the snow out.
- 10. recognize symptomsSkin numbness Redness or pain Affected skin looks white or grayish-yellow color Skin may feel unusually firm or waxy Many times the affected person is not aware until someone else points it out because the frozen tissue is numb. Normal Early symptoms of frostbite
- 11. what to do when frostbite strikesCall the doctor/go to an emergency facility Get to a warm place Remove wet clothes Don’t rub/massage affected areas Don’t walk on feet if affected as it can increase damage for mild cases:Gently rewarm frostbitten areas by soaking in warm water for 15–20 minutes. Make sure the water is not hot! Avoid rewarming with direct heat like a stove or heating pad – this can cause burns.
- 12. Frostbite requires medical attention because it can damage skin, tissues, muscle and bone.Severe frostbite can even cause infection and nerve damage. The mildest version of frostbite, called frostnip, can be treated through rewarming, but if you feel you or your child has frostbite call your doctor immediately or visit an immediate care facility.
