Core body temperature cbt is an important and commonly used indicator of human health and endurance performance. The body is usually very effective in maintaining core body temperature in a narrow and safe range.
Clinical Guidelines Nursing Temperature Management
Core body temperature measurement sites. Ear temperature measurement may be acceptable for observing trends in body temperature but is less useful in consistently identifying and diagnosing fever. The suggestion threshold for the forehead temperature is 36 c for screening of fever. Measuring core body temperature is necessary to understand the effect of environmental conditions on the body. Measuring core temperature. The standard operating procedure sop for the measurement of body temperature using an infrared thermometer was proposed. 2 autonomic as well as behavioral responses to changes in temperature maintain homeostasis or a range of normal around 37 c.
Climatic injuries including hypothermia hyperthermia and heat stroke are common in many sports activities. Sites which have been used for measurement of cbt include the pulmonary artery the esophagus the rectum and the tympanic membrane. Monitoring internal body tc accurately requires invasive methods of measurement. A rise in baseline cbt can be attributed to an onset of flu infection or even thermoregulatory failure when it becomes excessive. The measurement values for wrist temperature show significant offsets with the tympanic temperature and cannot be used to screen fevers. Body core temperature tc measurement for the sportsperson can influence individual performance and may help to prevent injuries.
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. During exercise particularly in extreme conditions the temperature may push the boundaries of this range. The measurement of core body temperature may seem simple but several issues affect the accuracy of the reading. Core body temperature measurement. As with rectal measurement sites tympanic thermometers may give slightly higher readings with the average temperature around 995 f. Youve probably had your temperature taken many times in your life.
These include the measurement site the reliability of the instrument and user technique pusnik and miklavec 2009. 1 core body temperature is regulated by both peripheral and central receptors that are integrated within the hypothalamus. Maybe you had a parent who could place a hand on your forehead and know in an instant whether. The pulmonary artery catheter which measures blood temperature is considered the gold standard for measuring core temperatures. Accurate measurement of core body temperature involves invasive medical procedures in hospital so it is a persons peripheral body temperature their skin level temperature that is commonly measured in non invasive sites such as the mouth ear armpit and less frequently rectum because these areas are easily accessible and are believed to provide the best estimation of the core body. Until recently direct measurement of core body temperature required either indigestible or surgical insertion of a probe.
