How does a tympanic thermometer work? - Answers Uses a sensor probe to measure infrared
heat produced by tympanic membrane (shares its blood supply with the hypothalamus)
Why is technique important when taking temperature with a tympanic thermometer? - Answers
Probe needs to be positioned in the external auditory canal (EAC) at the appropriate angle to get
an accurate reading - the position of this changes with age
