A rectal temperature is generally considered to be the most accurate and the standard for monitoring the core body temperature but it is generally not recommended for use in patients due to the risk of rectal perforation and tears with this method. 347 under skill 21 1 q 2. Have a separate thermometer to use for oral than for rectal. These include the measurement site the reliability of the instrument and user technique pusnik and miklavec 2009. In the united states temperatures are often measured in degrees fahrenheit. Monitoring internal body tc accurately requires invasive methods of measurement.

Many physicians feel that using the electronic termometer is more accurate than using a tympanic thermometers for an ill adult. Measuring body temperature is one of the oldest methods to discern a problem in both medical and nonmedical fields1 in fact proper functioning of the body is dependent upon keeping the body temperature within the normal range 372c378c because an increase 415c or decrease 30c in body temperature can lead to death23 accurate determination of body temperature in. In the early 2000s ingestible thermistors in capsule form were produced allowing the temperature inside the digestive tract to be transmitted to an external receiver. As with rectal measurement sites tympanic thermometers may give slightly higher readings with the average temperature around 995 f. Climatic injuries including hypothermia hyperthermia and heat stroke are common in many sports activities. 2 autonomic as well as behavioral responses to changes in temperature maintain homeostasis or a range of normal around 37 c.

The measurement of core body temperature may seem simple but several issues affect the accuracy of the reading. The pulmonary artery catheter which measures blood temperature is considered the gold standard for measuring core temperatures. Thermometers show body temperature in either degrees fahrenheit f or degrees celsius c. 1 core body temperature is regulated by both peripheral and central receptors that are integrated within the hypothalamus. 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. The standard in most other countries is degrees celsius.

Most people think a normal body temperature is an oral temperature by mouth of 986f. P 368 fourth bullet under key points critical thinking question. Measurement by tympanic thermometer comes closest to core body temperature. The rectal or vaginal temperature is generally considered to give the most accurate assessment of core body temperature particularly in hypothermia. One study found that these were comparable in accuracy to rectal temperature. Body core temperature tc measurement for the sportsperson can influence individual performance and may help to prevent injuries.

This results in less blood flowing outwards and concentrates heat at the core where the majority of vital organs are located. Because body temperature is a measure of internal thermal energy the most accurate measurements involve invasive methods such as putting a temperature sensor into the esophagus or urinary tract.
