They occur at the start of raising body temperature. They are a symptom that discovers a pathological condition as they are accompanied by vegetative disorders [heart failure, breathing difficulties, disturbances of consciousness], which in extreme cases can cause death. Measurement of body temperature, which is one of the vital signs, indicator of the basic functions of the body as well as an indication that the body of the event of a certain change, requires a certain skill and the use of appropriate measurement instrument [thermometer]. Selection and use of the measuring instrument depends on the education of patients [and/or parents], and its proper application to determine the deviation from the normal body temperature of its relevant value to determine the specific changes in the body.
