When the thermometer is placed beneath the tongue of the patient, the mercury expands and pushes through the constriction but when the thermometer is removed from the mouth, the constriction prevents the expanded mercury in the stem from falling back into the bulb. Since the temperature of the human body varies over a short range, the thermometer scale is marked from 95F to 110F or 35oC to 43oC. Giuliano et al found that oral measurements using an electronic thermometer produced more accurate and reproducible measurements than tympanic thermometers and therefore recommend these be used when pulmonary artery catheter placement is not indicated.17 Pugh-Davies et al found that although the average accuracy of oral temperature measures taken with mercury-in-glass and electronic thermometers were not significantly different, the electronic thermometers produced greater fluctuation of readings with up to 23% of electronic measurements differing by 0.5° C or more when only 6% of mercury-in-glass thermometer readings varied this much.19, Dr.Anika Niambi Al-Shura BSc., MSOM, Ph.D, in Physical Examination in Cardiovascular Chinese Medicine, 2014.

The mercury-in-glass, liquid crystal thermometers, or “tympanic” infrared thermometers are unsuitable for monitoring extreme hyperthermia or even mild hypothermia. Can A Clinical Thermometer Be Used To Measure The Temperature Of Boiling Water?Why? An increase in this temperature gradient indicates that peripheral vasoconstriction is occurring and the various possible causes of this should be investigated. Laboratory thermometers are capable of accurately measuring temperature variations in a variety of mediums, including some caustic to human skin. Rectal readings on average are the highest and axillary ones the lowest (Fig. It may seem strange to take an armpit reading for an adult, but in many cases the reading will provide the same results as ear or mouth. Probe sizes of thermometers are usually suitable for placement in the rectum of all commonly used species, but smaller probe sizes need to be used in mice (Fig. Cases of HA-CDAD in HCP have occurred.
