Hypothermia needs to be identified as hypothermia caused by hypothermia or as a result of low basal metabolic rate. 1. Hypothermia is caused by infectious factors, when the body temperature is lower than 35.5℃, and is accompanied by chills, chills, wet and cold body, wet and cold skin, pale skin, unmeasured blood pressure, fine and rapid pulse, low urine and other factors. 2. If the hypothermia is caused by infectious shock, septic shock, or hemorrhagic shock, it is necessary to go to the emergency department of the hospital immediately for resuscitation treatment. 2. If the hypothermia is caused by low basal metabolic rate, such as hypothyroidism and hyperalgesia, symptomatic treatment can be performed. 3. If the hypothermia is caused by cold, it can be treated with symptomatic treatment.
