Core body temperature measurement sites. This would include vital organs such as the heart liver and. Rectal readings are higher than oral readings while armpit readings tend to be lower. The pulmonary artery catheter which measures blood temperature is considered the gold standard for measuring core temperatures. Rectal temperature the use of a rectal probe in the past has been a common method to measure body temperature during exercise testing and is one of the most accurate methods. Body temperature readings vary depending on where on the body a person takes the measurements. The mercury thermometer most commonly used to measure oral temperature toral has been almost exclusively the only instrument for measuring tc since the 18th century.

The most common ones are the mouth the ear the armpit and the rectum. They work by measuring tympanic membrane temperature. 2 autonomic as well as behavioral responses to changes in temperature maintain homeostasis or a range of normal around 37 c.
Rectal tre and oesophageal temperatures toes have been the most preferred measurement sites employed in thermoregulatory investigations. The literature suggests that this is an unreliable site for estimating core body temperature because there are no main blood vessels around this area sund levander and grodzinsky 2009. Ear thermometer these are becoming popular as a method for measuring deep body core temperature. Your body temperature can be measured in many places on your body. Temporal measurements are closer to true core body temperature and provided that the probe has been properly positioned will give readings that are closer to average body temperatures of 986 f.

As with rectal measurement sites tympanic thermometers may give slightly higher readings with the average temperature around 995 f. Temperature is measured at the axilla by placing the thermometer in the central position and adducting the arm close to the chest wall. Temperature can also be measured on your forehead. The temperature of the inner parts of your body.
