• #1 Heatstroke – Symptoms and causes – Mayo Clinic

  https://www.mayoclinic.org/diseases-conditions/heat-stroke/symptoms-causes/syc-20353581

  Heatstroke symptoms include: […] A core body temperature of 104 degrees Fahrenheit (40 degrees Celsius) or higher is the main sign of heatstroke. […] Confusion, agitation, slurred speech, irritability, delirium, seizures and coma can all result from heatstroke. […] In heatstroke brought on by hot weather, skin feels hot and dry to the touch. However, in heatstroke brought on by strenuous exercise, sweating may be profuse. […] Someone with heatstroke may feel sick to their stomach or vomit. […] Skin may turn red as body temperature increases. […] Breathing may become rapid and shallow. […] Pulse may significantly increase because heat stress places an extreme burden on the heart to help cool the body. […] Heatstroke may cause the head to throb. […] If you think a person may be experiencing heatstroke, seek immediate medical help.

  Clinically, 2 forms of heat stroke are differentiated: classic, or nonexertional, heat stroke (NEHS) and exertional heat stroke (EHS). NEHS, which occurs during environmental heat waves, is more common in the very young and the elderly and should be suspected in children, elderly persons, and chronically ill individuals who present with an altered sensorium. NEHS occurs because of failure of the body’s heat dissipating mechanisms. […] On the other hand, EHS affects young, healthy individuals who engage in strenuous physical activity, and EHS should be suspected in all such individuals who exhibit bizarre, irrational behavior or experience syncope. EHS results from increased heat production, which overwhelms the body’s ability to dissipate heat. […] EHS is characterized by hyperthermia, diaphoresis, and an altered sensorium, which may manifest suddenly during extreme physical exertion in a hot environment.

  Heat stroke is a life-threatening condition in which heat overwhelms your bodys ability to manage its temperature. Symptoms include dizziness, fainting, blurred vision, slurred speech and confusion. […] Heat stroke causes your body temperature to soar to dangerous levels, typically above 104 degrees Fahrenheit (40 degrees Celsius). […] Heat stroke signs and symptoms include: High internal (core) body temperature, typically over 104 degrees Fahrenheit (40 degrees Celsius). Behavior changes like agitation or aggression. Blurred vision. Confusion. Delirium. Dizziness. Fainting (syncope). Fast heart rate (tachycardia). Fast, shallow breathing (tachypnea). Low blood pressure (hypotension). Nausea and vomiting. Seizures. Slurred speech. Skin color changes either flushed or paler than usual. Skin thats dry (classic heat stroke) or sweaty (exertional heat stroke). Weakness.

  Heatstroke is a severe heat-related illness involving an elevation in body temperature, typically but not always greater than 40 C. The patient has clinical signs of central nervous system dysfunction that may include confusion, ataxia, delirium, or seizures brought on after strenuous physical exertion or exposure to hot weather. […] Heat stroke is a clinical constellation of symptoms that include a severe elevation in body temperature, typically, but not always, greater than 40C. Also, there must be clinical signs of central nervous system dysfunction, including ataxia, delirium, or seizures, in the setting of exposure to hot weather or strenuous physical exertion.

  When the summer heats up, many of us try to stay indoors as much as possible. But there are times when you need to be outside for work, events and activities. Excessive heat can lead to dehydration, heat exhaustion and heat stroke. We explain the different symptoms you should look for and ways to help prevent and treat each one. […] Heat exhaustion is caused by your body’s loss of water and salt. This is usually caused by a lot of sweating, especially in hot conditions. It’s an early stage of heat stroke. […] Heat stroke is a very dangerous condition. It happens when the body can no longer cool down properly. This can cause the body temperature to rise to 106° F rapidly. Heat stroke can cause permanent disability or death if emergency treatment isn’t given. […] Symptoms of heat stroke include confusion or slurred speech, loss of consciousness, hot, dry skin, seizures, extremely high body temperature (above 104° F), and rapid pulse and heart rate. If you see someone with these symptoms, call 911 right away.

  Heat stroke occurs when the body’s heat-regulating system is overwhelmed by excessive heat. The skin may be dry if the ability to sweat has been lost. It’s a life-threatening emergency and needs immediate medical care. […] As the condition worsens, the body reaches a point where it can no longer keep up with the heat it’s gaining. This is because the heart is unable to pump enough blood to meet the body’s cooling needs. As a result, the body temperature keeps rising (exceeds 104F or 40C), causing damage to cells and triggering an inflammatory response. […] If heat stroke persists for over 30 minutes, it becomes a critical situation demanding immediate medical attention. Whenever there is a suspicion of heat stroke or uncertainty about the gravity of the symptoms, it is vital to promptly reach out to a doctor or seek medical help without delay. Neglecting medical intervention can result in severe complications and potentially life-threatening circumstances.

  Heat exhaustion and heatstroke are part of a continuum of heat-related illness. […] Untreated heat exhaustion can progress to heatstroke, a much more serious illness involving central nervous system dysfunction such as delirium and coma. […] If a patient is suffering from heat-stroke, rapid diagnosis and effective cooling are crucial, because the condition triggers a series of metabolic events that may progress to irreversible injury or death. […] Heat exhaustion is a more common and less extreme manifestation of heat-related illness in which the core temperature is between 37C (98.6F) and 40C. Symptoms of heat exhaustion are milder than those of heatstroke, and include dizziness, thirst, weakness, headache, and malaise. […] Heatstroke is a much more severe entity than heat exhaustion. The diagnosis of heatstroke rests on two critical factors: hyperthermia and central nervous system dysfunction.

• #38 Heat Stroke Clinical Presentation: History, Physical Examination, Complications

  https://emedicine.medscape.com/article/166320-clinical

  Clinically, 2 forms of heat stroke are differentiated: classic, or nonexertional, heat stroke (NEHS) and exertional heat stroke (EHS). NEHS, which occurs during environmental heat waves, is more common in the very young and the elderly and should be suspected in children, elderly persons, and chronically ill individuals who present with an altered sensorium. NEHS occurs because of failure of the body’s heat dissipating mechanisms. […] On the other hand, EHS affects young, healthy individuals who engage in strenuous physical activity, and EHS should be suspected in all such individuals who exhibit bizarre, irrational behavior or experience syncope. EHS results from increased heat production, which overwhelms the body’s ability to dissipate heat. […] EHS is characterized by hyperthermia, diaphoresis, and an altered sensorium, which may manifest suddenly during extreme physical exertion in a hot environment.
