In contrast, monitoring the temperature in the oropharynx is considered to be less accurate than nasopharyngeal temperatureEsophageal temperature probes are often combined with esophageal stethoscopes, making the esophagus a particularly appealing site to monitor temperature in children. The most widely accepted definition of fever is rectal temperature of 38°C (100.4°F) or higher. We use cookies to personalize and improve your experience on our site. Currently, there is no accurate and easy method to measure core body temperature in a field setting. If patients have been lying with their ear on a pillow, allow 20 minutes to elapse so the temperature can normalise (Bridges and Thomas, 2009).Temperature is measured at the axilla by placing the thermometer in the central position and adducting the arm close to the chest wall.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). Conditions During High or Low Body Temperature. The axillary temperature may underestimate the core temperature if the room temperature is low or if room temperature intravenous fluids are infused at high flow rates, particularly in small children when the intravenous is infusing in the same extremity as the axillary temperature is monitored. A temperature over 100.4°F (38°C) most often means you have a fever caused by an infection or illness. It consists of the heat-loss centre, the heat-promoting centre and the pre-optic region, which analyse and coordinate responses to maintain body temperature within the homeostatic range (Marieb and Hoehn, 2010).Signals arrive at the thermoregulatory centre via afferent pathways from the sensory receptors in the skin and organs.

Operator error and poor technique are frequently cited problems (Farnell et al, 2005), so training is recommended. Low-reading thermometers may be of some use. A blanket warmer is also utilized to prevent hypothermia by delivering warmed air to an inflatable blanket surrounding the patient. As discussed previously in this chapter, temperature maintenance in the operating room is difficult for the infant and the small child; hypothermia is common in this group. The four sites that can be used to monitor body temperature are tympanic membrane, pulmonary artery, distal esophagus, and nasopharynx. The discrepancy is likely to be increased in areas of high blood flow, by increasing the irrigation flow rate, or by cooling the irrigant. Saline-irrigated catheters result in peak tissue heating several millimeters from the electrode-tissue interface. German doctor Carl Wunderlich identified the average body temperature of 98.6°F (37°C) during the 19th century. If the rate of heat generated equates to the rate of heat lost, the core body temperature will be stable (Tortora and Derrickson, 2011).All metabolising body cells manufacture heat in varying amounts. However, its reliability and validity have not been widely tested. Esophageal temperature is influenced by the great vessels and thus rapidly reflects changes in core temperature if the probe is in the middle or distal portion of the esophagus. This article reviews and compares the various methods available to nursesBody temperature is one of the four main vital signs that must be monitored to ensure safe and effective care. Pocock and Richards (2009) suggest that consciousness is lost 33°C. Clean-in-place operations range from 25 to 50°C depending on the cleaning needs of the system and the tolerance of the UF devices to elevated temperature. This article explains the importance of temperature regulation and compares methods of its measurement.Body temperature represents the balance between heat production and heat loss (Marieb and Hoehn, 2010). Acceptable ranges should be set during the process performance qualification (PPQ).The RTD (resistance temperature detector) has become the predominant temperature sensing device because of its accuracy (DIN/IEC 60751, Class A (0.15 ± 0.002×Some instruments, such as Coriolis-effect-based mass flow meters, have integral Temperature monitoring and regulation are crucial to ensure the safety of a surgical patient (Several methods are employed to equalize a patient's body temperature.
