- Assessment ofbody temperature: t Sites The sites used for taking temperature should be Closed to prevent air currents.. Have abundant blood supply. ~ ----~--==-==-===~~;:::========-~~~ Oral temperature There is a rich blood supply under the tongue, the thermometer should be placed under the tongue, because there is a rich of blood supply, and the patient's mouth should be closed. As a branch of the external carotid artery perf uses the area of the posterior sublingual pockets the oral temperature has been suggested to follow changes in core temperature closely. ~ ~~---=-==-==~~~___, ecta/ temperature ; ;2~~ The rectal site is thought to be an indication of the deep visceral temperature, through the iliac artery and the iliac vein. The rectal temperature is higher than at other places in steady state which is probably due to the low blood flow and high isolation of the area, giving a low heat loss There is a difference of O.SC0 between rectal and oral temperature ·rectal is higher·. c... *Axillary= +0.5 C0 c- *Rectal=-0.5 C0 ~Axnlary temperature The axillary site used for mouth breathing patients and the patient with oral inflammation or surgery. Axillary temperature is 0.5C0 lower than oral temperature. C 2-Aura/ temperature (the aural (ear) site) The tympanic membrane shares their blood supply from the internal and external carotid arteries and the area is relatively - devoid of metabolic activity.  ~ - Temporal Temperature c: temporal temperature is taken by using a device placed on the forehead. Temporal thermometers contain an infrared scanner that measures the heat on the surface of the skin resulting from blood moving through the temporal artery in the forehead. tt is a quick, noninvasive method, but accurate ~~---=:_..:::-=:.:::::=~~~- ~ ~ Tympanic membrane thermometer which consists of a small hand-held c device with a sensor probe and a disposable probe cover & connected with a battery-operated unit. c Chem/ca/ thermometer Are used most often by patients at home; it Includes: '- Disposable chemical single use thermometer: respond to body heat and chan~( · _ _ _ 1uu11 -=- This type has small chemical dots at one end that · ~ > l~ =----j  temperature sensitive strips C" Consists of reusable plastic strips containing heat-sensitive liquid crystals designed to measure body temperature. o The plastic strip is pressed onto the forehead and held in place until the colors stop changes ·about 15 seconds".
