39.2 ℃ is considered fever, the human body fever, according to the degree of fever can be divided into four levels, low fever refers to the body temperature is lower than 38 ℃, moderate fever refers to the body temperature in 38-39 ℃, high fever refers to the body temperature in the 39-41 ℃, high fever refers to the body temperature in the 41 ℃ or more. 39.2 ℃ in accordance with the degree of fever, more than 39 ℃, so it belongs to the range of high fever. If high fever occurs, it will cause a significant increase in heart rate and hypoxia of tissue cells. In order to ensure the blood supply of important organs, such as the heart, lungs, brain and other important blood supply, will cause peripheral vascular constriction, cold extremities. At this time, you need to drink more warm water to promote blood circulation and accelerate heat dissipation. If there are cardiac, pulmonary and other underlying diseases, it will cause the tissue hypoxia to be significantly aggravated, and even cyanosis. Physical cooling can be applied, and if physical cooling is ineffective, some antipyretic drugs can be applied for symptomatic treatment.
