Body temperature is generally considered normal between 36°C and 37.2°C. If it exceeds 37.2°C, it is considered a fever. There are many ways to measure body temperature, such as axillary temperature and oral temperature. The more common and accurate way is axillary temperature measurement. If there is a fever, it is necessary to take prompt cooling measures.
1. Oral temperature: Place the thermometer under the tongue. The normal temperature is 33.2~38.2°C. However, many factors can affect the test results, such as chewing, drinking tea, smoking, and rapid breathing, which are not suitable for critically ill patients and children.
2. Axillary temperature: The thermometer needs to be placed deep in the armpit. The position of the arm during measurement is fixed, typically between 35.5~37°C. However, excessive local sweat or low blood pressure can affect the measurement results. This method is not suitable for elderly, children, and critically ill patients who cannot cooperate.
3. Rectal temperature: Rectal temperature measurement is reliable and accurate. It is suitable for infants, with a normal range of 34.4-37.8°C. However, this method can cause discomfort.
4. Ear temperature: Ear temperature can reflect the temperature of the ear and is very convenient and fast. There is a certain difference in body temperature measured before and after the left and right ears. The normal ear temperature should be between 35.4-37.8°C.
