How to measure body temperature with mercury thermometer?
The triangle of the thermal probe is horizontally held in a place parallel to the line of sight of the eyes, and the hand is slowly rotated to see how many degrees of small thin lines are inside.

When reading, put the thermometer that has been measured for 5 minutes flat in front of your eyes, and see that the scale of the mercury column points to several large scales, 35-39℃, with millimeters as the dividing line and 10 units representing 0. 1℃. For example, 37.5℃ belongs to low fever, 37.2℃ belongs to normal body temperature, and above 39-40℃ belongs to high fever and ultra-high fever.

Mercury thermometer has three uses, the most commonly used one is to measure the temperature under the armpit, including oral temperature and rectal temperature. Rectal thermometry is mainly used for uncooperative babies, sweating under the armpit, not tightly clamped, uncooperative, which easily leads to temperature distortion. Temperature measurement in the mouth is worried about poisoning after mercury is broken, so the most commonly used is temperature measurement in the anus.

Precautions:

1. Pay attention to the range and dividing value of the thermometer before use.

2. When measuring, fully contact the glass bulb of the thermometer with the measured object.

3. When reading, wait until the pointer of the thermometer is stable before reading. When reading, the thermometer must still be in contact with the measured object, and the line of sight should be flush with the upper surface of the liquid column in the thermometer.

4. When infants, mental users and restless users measure rectal temperature, nurses should hold an anal meter to prevent the thermometer from breaking or entering the rectum, causing accidents.

5, the body is too thin, it is not appropriate to use the armpit table, users can measure the armpit temperature 30 minutes after taking a shower.
