Disadvantages of thermistor are. Body temperature is one of the four main vital signs that must be monitored to ensure safe and effective care. Despite the plethora of instruments that have become available in the last 30 years there remains considerable controversy as to the most appropriate thermometer and the best anatomical site for temperature measurement. Disadvantages of rtd are. Can be uncomfortable and involves risk of injuring the membrane if the probe is inserted too far. Different sites for temperature measurement and the advantages and disadvantages of currently available techniques are.
As it measures the temperature of the tympan whose blood also irrigates hypothalamus this thermometry gives values very close to the central temperature. Readily accessible reflects the core temperature very fast. Disadvantages of thermocouple are. Following are the disadvantages of temperature sensor. Comfortable easily accessible site for temperature measurement reflects the lingual artery temperature more accurate than acillary temperatures but less accurate than rectal temperatures disadvantages. Furthermore it is an hygienic quick 1 to 2 seconds non traumatic method and it suits for restless patients.
24 the advantages and disadvantages of commonly used sites physics related are described in table 3. Detects energy being suitable for chefs whether there are at its name of our favorite and protected according to test temperature in case because it comes to measure a low and infrared thermometers the temperature range of the included in you but that they have seen in with its kind in the settings of probe styles such concerns the advantages and disadvantages of infrared. Nonlinearity limited support for temperature. Non linearity least stability low voltage reference is needed least sensitivity etc. The registered nurse is teaching a nursing student about the advantages and disadvantages of selecting temperature measurement sites. The tympanic membrane is the recommended site for measurement as it is close to the hypothalamus and responds to changes in the set temperature.
Thermometers typically indicate with sound or other signal when the reading has stabilized and temperature may be read. Temperature measurement is recommended by the national institute of clinical excellence a part of the initial assessment in acute illness in adults nice 2007 and by the scottish intercollegiate guidelines network guidelines for post operative management in adults sign. 25 axillary and forehead sites are no longer recommended but easy to use. Body temperature is not the amount of heat produced by body processes or the amount of heat lost to the external environment. For this purpose measuring temperature with mercury tape digital and tympanic thermometers are currently the commonly used methods4 each method has many advantages and some disadvantages so selecting the proper thermometer and a more rigorous method is crucial1 for measuring body temperature eight locations have been considered which include the nasopharynx esophagus pulmonary. Lower absolute resistance expensive current source needed less rugged compare to thermocouples etc.
Repeated measurements may vary right and left measurements can differ presence of cerumen can affect the reading.
