Most Accurate Body Temperature Measurement

Regular digital thermometers use electronic heat sensors to record body temperature. The most accurate way to measure temperature is to take a rectal reading. Rectal temperatures provide the best readings for infants especially those 3 months or younger as well as children up to age 3.

What Is The Most Accurate Way To Take A Temperature Is Oral

Armpit temperatures are usually the least accurate.

Most accurate body temperature measurement. Rectal or oral temperature measurements are generally more accurate than the other two measurements. This makes the insertion of thermometer easier. For the adults any one of these four places can be the best place as long as the slight differences are taken into. These thermometers can be used in the rectum mouth or armpit.

Wait at least 1 hour after heavy exercise or a hot bath before measuring body temperature. Apply a lubricant on the bulb of the thermometer. A jelly like vaseline would do. Wait for 20 to 30 minutes after smoking eating or drinking a hot or cold liquid.

2 autonomic as well as behavioral responses to changes in temperature maintain homeostasis or a range of normal around 37 c. Rectal temperature gives the most accurate measurement of body temperature. You need to have an accurate temperature measurement to determine if a fever is present. The normal axillary temperature range is approximately between 347 c and 373 c.

Fever in most adults a fever is an oral temperature above 1004f 38c or a rectal or ear temperature above 101f 383c. 1 core body temperature is regulated by both peripheral and central receptors that are integrated within the hypothalamus. The pulmonary artery catheter which measures blood temperature is considered the gold standard for measuring core temperatures. In adult patients the temperature of an axillary measurement is lower than a rectal measurement up to 19 c.

In general measurement of body temperature from the rectum tends to give higher readings compared to axillary measurement. However this is only possible up to a certain body mass and this type of measurement also takes a long time. In the case of children make the child lie prone on a lap or soft padded surface.
