What Are the Symptoms Of Hypothermia?

Hypothermia refers to hypothermia when the body's temperature is lower than the normal range due to reduced heat production or increased heat dissipation caused by various reasons. When the body temperature is lower than 35 , the body temperature is said not to rise.

Hypothermia

Basic information on hypothermia

Hypothermia refers to hypothermia when the body's temperature is lower than the normal range due to reduced heat production or increased heat dissipation caused by various reasons. When the body temperature is lower than 35 , the body temperature is said not to rise.

Hypothermia

(1) Clinical classification of hypothermia (taking oral temperature as an example) Mild: 32-35 ° C, Moderate: 30-32 ° C, Severe: 30 ° C Mydriasis is dilated, and the death caused by light reflection disappears. 25

(2) The main clinical manifestations are pale and cold skin, purple lips and earlobe, mild tremor, slow heartbeat breathing, reduced blood pressure, decreased urine output, disturbance of consciousness, and possible coma in the late stage.

Hypothermia

Hypothermia can lead to the acceleration of all physiological functions, including cardiovascular and respiratory system, nerve conduction, mental acuity, neuromuscular reaction time and metabolic rate. In young children, the low temperature caused by immersing the whole body in water close to freezing can protect the brain during hypoxia.

Decreased core body temperature can lead to apathetic drowsiness, clumsy hands and feet, confusion, irritability, illusoryness, slowed or stopped breathing, slowed heartbeat, irregularity, and finally stopped. But as long as the patient is not warm, the patient should not be considered dead. A rectal temperature of <34 ° C helps to distinguish it from similar symptoms due to heart disease, diabetic coma, insulin overdose, cerebrovascular accident, or drug abuse. Ordinary clinical thermometers cannot measure very low body temperature when the body temperature is too low. A special hypothermia meter must be used. If there is only a standard clinical thermometer, the mercury column cannot rise above 34 ° C to indicate that the body temperature is too low.
