Comparison of three different thermometers in evaluating the body temperature of healthy young adult individuals

Abstract

The aim of this study was to compare the measurement values obtained with a non-contact infrared thermometer, a tympanic thermometer and a chemical dot thermometer. The research population was composed of students studying in two departments of a university in Ankara. A total of 452 students who fit the inclusion criteria of the study and volunteered to participate were included in the sample. Body temperature measurements with different thermometers were performed by the same researcher at the same room temperature. Data were analyzed in a computerized environment by SPSS 15.0 statistical program pack and Bland-Altman graph. Mean age of healthy young adults participating in the study was 19.66 ± 0.94, and 55.1% of them were female. The agreement limits for non-contact infrared and chemical dot was between -1.30 and 0.32°C; for non-contact infrared and tympanic was between -1.26 and 0.13°C; and for chemical dot and tympanic -0.89 and 0.74°C. It was determined that, although the measurement values of the tympanic membrane and chemical dot thermometers conformed with each other, the conformity of the non-contact infrared thermometer was weak.

Force protection in contingency operations: an evaluation of temperature monitoring in Sierra Leone

“…Numerous thermometers are available performing similar roles, and as such the standardisation of device usage and reporting is poor. The literature is supportive of the use of tympanic thermometry10 11 and suggests that infrared skin scanning thermometers are less reliable 12. In the adult population, the ability to accurately estimate core temperature is demonstrated by these devices, although there is unsatisfactory agreement when comparing them against each other 13…”

Perfil de termorregulaçãoe desfecho clínico em pacientes críticos com sepse

“…A mensuração da tc deve ser preferencialmente realizada por métodos que refletem a temperatura central (nasofaringe, esôfago, membrana timpânica, artéria temporal, artéria pulmonar, bexiga) (41), pois estes são mais precisos e sensíveis às mudanças de temperatura. Os instrumentos de mensuração da tc central refletem a temperatura do suprimento sanguíneo da artéria carótida, responsável pelo provimento de sangue para o centro termorregulador do organismo -o hipotálamo (42). Contudo, os instrumentos de medida da tc central, por serem invasivos, estão associados a maior número de complicações (42).…”

Intraoperative body temperature control: esophageal thermometer versus infrared tympanic thermometer

“…Currently, different forms of temperature measurement are available which can indicate core or peripheral temperature, as well as instruments that provide core temperature measurements, meaning those that indicate the temperature of the carotid artery blood supply, being responsible for the blood supply to the organism's thermoregulatory center (the hypothalamus) (4,7) . In general, methods that indicate core body temperature are invasive, and for this reason they are associated with a greater number of complications and/or infectious problems (7) .…”

“…In general, methods that indicate core body temperature are invasive, and for this reason they are associated with a greater number of complications and/or infectious problems (7) . Thus, non-invasive measures are expected to be able to provide reliable and safe measurements of the patient's body temperature.…”

“…Problems related to the reliability of their results, in the sense of actually reflecting the tympanic temperature and not the temperature of the auditory canal or the environment have been corrected (13)(14) . As the reading of vital signs (with temperature among them) are frequently performed by the nursing team (7) , it is interesting to know and understand the practical application of the tympanic thermometer in intraoperative temperature measurement, thus guaranteeing an independent performance of perioperative nursing in relation to patients' body temperature control throughout the perioperative period, as well as a more adequate control of body temperature maintenance devices.…”
