Hypothermia

Hypothermia be defined as a body core temperature below  insyd humans. Symptoms dey depend on de temperature. Insyd mild hypothermia, der be shivering den mental confusion. Insyd moderate hypothermia, shivering stops den confusion dey increase. Insyd severe hypothermia, der fi be hallucinations den paradoxical undressing, insyd wich a person komot dema clothing, as well as an increased risk of de heart stopping.

Hypothermia get two main types of causes. E classically dey occur from exposure to cold weather den cold water immersion. E sanso fi occur from any condition wey dey decrease heat production anaa dey increase heat loss. Commonly, dis dey include alcohol intoxication buh sanso fi include low blood sugar, anorexia, den advanced age. Body temperature usually be maintained near a constant level of  thru thermoregulation. Efforts to increase body temperature dey involve shivering, increased voluntary activity, den putting on warmer clothing. Hypothermia fi be diagnosed based on either a person ein symptoms insyd de presence of risk factors anaa by measuring a person ein core temperature.

De treatment of mild hypothermia dey involve warm drinks, warm clothing, den voluntary physical activity. Insyd those plus moderate hypothermia, heating blankets den warmed intravenous fluids be recommended. People plus moderate anaa severe hypothermia for be moved gently. Insyd severe hypothermia, extracorporeal membrane oxygenation (ECMO) anaa cardiopulmonary bypass fi be useful. Insyd those widout a pulse, cardiopulmonary resuscitation (CPR) be indicated along plus de above measures. Rewarming typically be continued til a person ein temperature be greater dan . If der be no improvement at dis point anaa de blood potassium level be greater dan 12 millimoles per litre at any time, resuscitation fi be discontinued.

Hypothermia be de cause of at least 1,500 deaths a year insyd de United States. E be more common insyd older people den males. Na one of de lowest documented body temperatures from wich sam bro plus accidental hypothermia survive be  insyd a 2-year-old boy from Poland dem name Adam. Na dem describe survival after more dan six hours of CPR. Insyd individuals for whom ECMO anaa bypass be used, survival be around 50%. Na deaths secof hypothermia play an important role insyd chaw wars.

De term be from Greek ῠ̔πο (ypo), wey dey mean "under", den θέρμη (thérmē), wey dey mean "heat". De opposite of hypothermia be hyperthermia, an increased body temperature secof failed thermoregulation.
