Body thermometry is the measurement of body temperature. For thermometry of the body, the most commonly used medical thermometer, which has a scale from 35 (34) to 42 ° with divisions by tenths of a degree.
After the end of body thermometry, the thermometer must be shaken several times so that the mercury column is lowered into the tank. There is a constriction in the capillary of the medical thermometer that prevents the free return of mercury to the tank at the end of the heat exposure.

Thermometry of the body is carried out before eating in the position of the patient lying down or sitting for 10 minutes. Temperature measurement is usually made in the armpit (Fig. 1). The skin of the armpit should be wiped dry beforehand.
Body temperature in infants is sometimes measured in the inguinal fold or in the rectum ; in the latter case, before measuring the temperature, the thermometer should be smeared with petroleum jelly. In rare cases (for example, with very strong anxiety of patients), instead of body thermometry, the temperature of the newly released urine can be measured.
Body thermometry is usually carried out 2 times a day: in the morning (at 7–8 hours) and in the evening (at 17–18 hours). In some diseases (for example, rheumatism , tuberculosis), to catch short-term fluctuations in temperature during the day, body thermometry is carried out every two or four hours. The paramedic should immediately record the obtained data in the history of the disease , and sometimes graphically depict it as a curve on the temperature sheet (Fig. 2). After measuring the body temperature, the thermometer should be placed in a disinfectant solution.
For body thermometry, in addition to medical thermometers, use minute thermometers (allowing to measure temperature for 2-3 minutes), electrothermometers (convenient for mass examinations and for measuring the local temperature of various skin and mucous membranes), as well as thermographs (allowing to record temperature body for a long time).
