What Are The Symptoms Of Hypothermia
Cold: Hypothermia is caused by loss of body heat. This can occur in injury, immersion in water, surgery, exposure outdoors, etc. Some conditions call for deliberately induced hypothermia such as stroke and post-cardiac arrest patients. Severe hypothermia requires medical intervention, mild hypothermia-a cup of hot chocolate. ...Read more
Warm body...: There are many ways to slowly warm a patient who has hypothermia. Examples include, warm blankets, warmed IV fluids, warm water peritoneal lavage, hemodialysis with warming of blood before it is returned to the body, etc. Some of these maneuvers are very invasive and so are only used if initial, less invasive maneuvers fail. Taking off cold, wet clothing is important part of warming process. ...Read more
Low body temp: Definition: below 95 degrees: depending on the body temp: between 95-89.6 - poor peripheral circulation, shivering, apathy, lethargy, confusion and rapid heart rate; between 89.6-82.4 - shivering stops, increased confusion or delirium, slowing heart rate and irregular heart rate; below 82.4 coma, ventricular fibrillation (type of cardiac arrest), may look dead; below 68 brain activity stops. ...Read more
Circumstance depends: walking/hiking outdoors with hypothermia can make you slow and sleepy, with risk of more damage as you cool down further. Frostbite results when parts of you get too cold and freeze. In a different setting, like after injury or surgery, with heavy bleeding, hypothermia throws off the body's ability to clot and stop the bleeding. Other basic functions get thrown off as well. ...Read more
Yes: Hypothermia can occur in temperature exposures of 50f or higher in wet and windy weather. Certain factors can predispose people to developing hypothermia, such as alcohol consumption. Home treatment may raise body temperature to normal in some mild cases of hypothermia but this can require hospital care if moderate to severe. ...Read more
Very little time. : Hypothermia is defined as having a core body temperature below 95 degrees f or 35 degrees c. How long it takes to drop your body temperature to that degree is dependent on your exposure and the environmental conditions. Your body can lose heat 25 times faster in cold water than cold air. Children and elderly are at higher risk of hypothermia. ...Read more
Hartd to say: There have been many times that a "dead" person has been brought to the er only to have them be revived through warming and life support. There is a saying that "they are not dead until they are warm and dead". There are documented cases where that motto has been forgotten and the patient wakes up in the morgue! ...Read more
Many causes: One category of causes is increased heat loss, such as environmental exposure, drug side-effects, and skin disorders. Another category is decreased heat production, such as from hypothyroidism, hypoglycemia or malnutrition. You can also think about impaired regulation, typically from neurologic disease. In addition, a condition like sepsis (associated with severe infection) can cause hypothermia. ...Read moreSee 1 more doctor answer
Many signs: Some of the first signs are high respiratory rate, high heart rate, confusion, and shivering. People with hypothermia will develop confusion and possibly slurred speech. As hypothermia becomes worse, both heart rate and respiratory rate decrease, and shivering may decrease. People will become very sleepy and may hallucinate. Note that, while common, not all people will have these signs. ...Read more
