Abstract:
Infrared thermometry has certain advantages over traditional oral thermometry including quick, non-invasive administration and an absence of required consumables. This study compared the performance of tympanic, temporal artery and forehead contactless thermometers with traditional oral electronic thermometer as the reference in measuring temperature in outpatients in a Nigerian secondary care hospital. A convenience sample of 100 male and 100 female adult patients (Mean age = 38.46 years, SD = 16.33 years) were recruited from a secondary care hospital in Kano, Nigeria. Temperature measurements were taken from each patient using the tympanic, temporal artery and contactless thermometers and oral electronic thermometer. Data was analyzed to assess bias and limits using scatterplots and Bland-Altman charts while sensitivity analysis was done using ROC curves. The tympanic and temporal artery thermometers systematically gave higher temperature readings compared to the oral electronic thermometer. The contactless thermometer gave lower readings compared to the oral electronic thermometer. The temporal artery thermometer had the highest sensitivity (88%) and specificity (88%) among the three infrared thermometers. The contactless thermometer showed a low sensitivity of 13% to detect fever greater than 38 °C. Our study shows that replacing oral thermometers with infrared thermometers must be done with caution despite the associated convenience and cost savings.

Abstract:
Background and Purpose: Technology of ear infrared (IR) thermometers has improved. This study compared a modern ear thermometer to forehead or temporal artery thermometers. Methods: Temperatures were measured with a heated-tip ear thermometer, a temporal artery thermometer, 3 forehead thermometers, and a thermistor-based reference thermometer in monitor mode. Results: In 171 subjects, mean bias with the forehead thermometers was significantly higher (p< .001) than with the ear thermometer (0.01 °C ± 0.41 °C). In 64 febrile subjects, bias with the ear thermometer was significantly lower than with 3 of the other thermometers. A false-negative reading was less likely with the ear thermometer (8%) versus the others (55%, 56%, 28%, and 47%). Conclusions: Modern ear thermometry provides more precise measurements closer to those of a reference thermometer and is less likely to give false-negative readings than forehead or temporal artery measurements.

Abstract:
Clinical thermometers are considered to bethe most important diagnostic devices in diagnosis of any febrile disorders. The last two decades have witnessed major changes in the clinical thermometry technology after the introduction of various types of modified thermometer for convenient diagnosis. Mercury thermometer stands up as the gold standard method for assessment of body temperature, but they are gradually getting replaced with newer devices that not only offer faster readings but inconvenience to the patients is also minimalized. This review focuses on accuracy, pros and cons of gold standard mercury-in-glass thermometer, and also various technologically advanced thermometers like electronic digital thermometer, tympanic thermometer, non-contact infrared thermometer, liquid crystal skin thermometer, pacifier thermometer, and smart thermometer. Various studies suggest that different factors can cause variation in the accuracy provided by such devices, like physical barriers, and calibration, including the manner in which they are used. The review does not conclude that a particular clinical thermometer has better accuracy and reliability than the other. Rather, there were contradictory findings for all of the clinical thermometers evaluated.

Abstract:
The purpose of this study was to determine which thermometry technique is the most accurate for regular measurement of body temperature. We compared seven different commercially available thermometers with a gold standard medical-grade thermometer (Welch-Allyn): four digital infrared thermometers (Wellworks, Braun, Withings, MOBI), one digital sublingual thermometer (Braun), one zero heat flux thermometer (3M), and one infrared thermal imaging camera (FLIR One). Thirty young healthy adults participated in an experiment that altered core body temperature. After baseline measurements, participants placed their feet in a cold-water bath while consuming cold water for 30 min. Subsequently, feet were removed and covered with a blanket for 30 min. Throughout the session, temperature was recorded every 10 min with all devices. The Braun tympanic thermometer (left ear) had the best agreement with the gold standard (mean error: 0.044 °C). The FLIR One thermal imaging camera was the least accurate device (mean error: −0.522 °C). A sign test demonstrated that all thermometry devices were significantly different than the gold standard except for the Braun tympanic thermometer (left ear). Our study showed that not all temperature monitoring techniques are equal, and suggested that tympanic thermometers are the most accurate commercially available system for the regular measurement of body temperature.

Abstract:
The options for primary thermometry at ultra-low temperatures are rather limited. In practice, most laboratories are using 195 Pt NMR thermometers in the microkelvin range. In recent years, current sensing direct current superconducting quantum interference devices (DC-SQUIDs) have enabled the use of noise thermometry in this temperature range. Such devices have also demonstrated the potential for primary thermometry. One major advantage of noise thermometry is the fact that no driving current is needed to operate the device and thus the heat dissipation within the thermometer can be reduced to a minimum. Ultimately, the intrinsic power dissipation is given by the negligible back action of the readout SQUID. For thermometry in low-temperature experiments, current noise thermometers and magnetic flux fluctuation thermometers have proved to be most suitable. To make use of such thermometers at ultra-low temperatures, we have developed a cross-correlation technique that reduces the amplifier noise contribution to a negligible value. For this, the magnetic flux fluctuations caused by the Brownian motion of the electrons in our noise source are measured inductively by two DC-SQUID magnetometers simultaneously and the signals from these two channels are cross-correlated. Experimentally, we have characterized a thermometer made of a cold-worked high-purity copper cylinder with a diameter of 5 mm and a length of 20 mm for temperatures between 42 μ K and 0.8 K. For a given temperature, a measuring time below 1 min is sufficient to reach a precision of better than 1%. The extremely low power dissipation in the thermometer allows continuous operation without heating effects.

Abstract:
BACKGROUND: Despite increasing use of tympanic thermometers in critically ill patients who do not have a pulmonary artery catheter in place, variations in measurements obtained with the thermometers are still a problem. OBJECTIVE: To compare the range of variability between tympanic and oral electronic thermometers. METHODS: Subjects were a convenience sample of 72 patients admitted to a 24-bed adult medical-surgical intensive care unit. For each patient, temperatures were measured concurrently (within a 1-minute period) with an oral (Sure Temp 678) thermometer, a pulmonary artery catheter (Baxter VIP Swan-Ganz Catheter), and 2 tympanic (FirstTemp Genius II and ThermoScan Ear Pro-1) thermometers. Each subject was used up to 3 times for data collection. Measurements obtained with the oral and tympanic thermometers were compared with those obtained with the pulmonary artery catheter. Nonparametric analysis of data was used. RESULTS: The magnitude of error for the ThermoScan tympanic thermometer differed significantly from that of the Genius II tympanic thermometer and the SureTemp oral thermometer (P &lt; .001). Application of the Bland and Altman method to frame the data on the basis of an accuracy tolerance zone of +/-0.5 degrees C indicated variability with both the oral and tympanic methods. The overall degree of variability was lower for the oral thermometer. CONCLUSIONS: Oral thermometers provide less variable measurements than do tympanic thermometers. Use of oral thermometry is recommended as the best practice method for temperature evaluation in critical care patients when measurement of core temperature via a pulmonary artery catheter is not possible.

Abstract:
Background Current options for temperature measurement in children presenting to primary care include either electronic axillary or infrared tympanic thermometers. Non-contact infrared thermometers could reduce both the distress of the child and the risk of cross-infection. Objectives The objective of this study was to compare the use of non-contact thermometers with the use of electronic axillary and infrared tympanic thermometers in children presenting to primary care. Design Method comparison study with a nested qualitative study. Setting Primary care in Oxfordshire. Participants Children aged ≤ 5 years attending with an acute illness. Interventions Two types of non-contact infrared thermometers [i.e. Thermofocus (Tecnimed, Varese, Italy) and Firhealth (Firhealth, Shenzhen, China)] were compared with an electronic axillary thermometer and an infrared tympanic thermometer. Main outcome measures The primary outcome was agreement between the Thermofocus non-contact infrared thermometer and the axillary thermometer. Secondary outcomes included agreement between all other sets of thermometers, diagnostic accuracy for detecting fever, parental and child ratings of acceptability and discomfort, and themes arising from our qualitative interviews with parents. Results A total of 401 children (203 boys) were recruited, with a median age of 1.6 years (interquartile range 0.79–3.38 years). The readings of the Thermofocus non-contact infrared thermometer differed from those of the axillary thermometer by –0.14 °C (95% confidence interval –0.21 to –0.06 °C) on average with the lower limit of agreement being –1.57 °C (95% confidence interval –1.69 to –1.44 °C) and the upper limit being 1.29 °C (95% confidence interval 1.16 to 1.42 °C). The readings of the Firhealth non-contact infrared thermometer differed from those of the axillary thermometer by –0.16 °C (95% confidence interval –0.23 to –0.09 °C) on average, with the lower limit of agreement being –1.54 °C (95% confidence interval –1.66 to –1.41 °C) and the upper limit being 1.22 °C (95% confidence interval 1.10 to 1.34 °C). The difference between the first and second readings of the Thermofocus was –0.04 °C (95% confidence interval –0.07 to –0.01 °C); the lower limit was –0.56 °C (95% confidence interval –0.60 to –0.51 °C) and the upper limit was 0.47 °C (95% confidence interval 0.43 to 0.52 °C). The difference between the first and second readings of the Firhealth thermometer was 0.01 °C (95% confidence interval –0.02 to 0.04 °C); the lower limit was –0.60 °C (95% confidence interval –0.65 to –0.54 °C) and the upper limit was 0.61 °C (95% confidence interval 0.56 to 0.67 °C). Sensitivity and specificity for the Thermofocus non-contact infrared thermometer were 66.7% (95% confidence interval 38.4% to 88.2%) and 98.0% (95% confidence interval 96.0% to 99.2%), respectively. For the Firhealth non-contact infrared thermometer, sensitivity was 12.5% (95% confidence interval 1.6% to 38.3%) and specificity was 99.4% (95% confidence interval 98.0% to 99.9%). The majority of parents found all methods to be acceptable, although discomfort ratings were highest for the axillary thermometer. The non-contact thermometers required fewer readings than the comparator thermometers. Limitations A method comparison study does not compare new methods against a reference standard, which in this case would be central thermometry requiring the placement of a central line, which is not feasible or acceptable in primary care. Electronic axillary and infrared tympanic thermometers have been found to have moderate agreement themselves with central temperature measurements. Conclusions The 95% limits of agreement are > 1 °C for both non-contact infrared thermometers compared with electronic axillary and infrared tympanic thermometers, which could affect clinical decision-making. Sensitivity for fever was low to moderate for both non-contact thermometers. Future work Better methods for peripheral temperature measurement that agree well with central thermometry are needed.

Abstract:
A 33-year-old man was referred to our hospital with chief complaints of fever, dizziness, and headache. Although he had recurring fever and dizziness for 7 months, neurological examination, magnetic resonance imaging, computed tomography, electrocardiograms, and blood tests were normal. He was diagnosed with functional hyperthermia, cervical vertigo, and tension headache and was treated with oral medication and physical therapy. After treatment, the dizziness and headache resolved; however, the fever and anxiety did not. During follow-up, he noticed differing results from different electronic thermometers. The physician decided to use an accurate analog thermometer, a gallium thermometer, in combination with the other thermometers. The results differed significantly among the thermometers, and the electronic thermometer readings were found to be inappropriately high. The physician made a diagnosis of pseudo-fever, and the patient recognized that the gallium thermometer’s results were the most accurate reflection of his physical condition, resolving his anxiety.

Abstract:
Body temperature measurement is one of the basic methods in clinical diagnosis. The problems of thermometry—interpretation of the accuracy and repeatability of various types of thermometers—are still being discussed, especially during the current pandemic in connection with the SARS-CoV-2 virus responsible for causing the COVID-19 disease. The aim of the study was to compare surface temperatures of the human body measured by various techniques, in particular a noncontact thermometer (infrared) and contact thermometers (mercury, mercury-free, electronic). The study included 102 randomly selected healthy women and men (age 18–79 years). The Bland–Altman method was used to estimate the 95% reproducibility coefficient, i.e., to assess the degree of conformity between different attempts. Temperatures measured with contact thermometers in the armpit are higher than temperatures measured without contact at the frontal area of the head. The methods used to measure with contact thermometers and a noncontact infrared thermometer statistically showed high measurement reliability. In order to correctly interpret the result of measuring human body temperature, it is necessary to indicate the place of measurement and the type of thermometer used.

Abstract:
• Background Recent research indicates that oral measurement of body temperature is a reliable option in orally intubated patients. In situations such as protective isolation, where dedicated electronic thermometers are not available, are single-use chemical dot thermometers an acceptable alternative?• Objective To determine the accuracy of single-use chemical dot thermometers in orally intubated adult patients.• Methods Subjects included a convenience sample of 85 adult patients admitted to 1 of 2 intensive care units (surgical trauma and neuroscience). For each patient, oral temperatures were measured concurrently (within 5 minutes) with a chemical dot thermometer and an electronic thermometer. The sequence of temperature measurements was alternated with each subsequent patient. Both thermometers were placed in the same posterior sublingual pocket opposite the side of the endotracheal tube.• Results Measurements obtained with electronic and single-use chemical dot thermometers correlated strongly (r = 0.937). With the chemical dot thermometer, body temperature was overestimated in 11.8% of the measurements and underestimated in 10.8% of the measurements by 0.4°C or more. The difference between oral temperatures measured with the 2 different thermometers was not related to the patient’s age, sex, or sublingual pocket location or to the order of thermometer use.• Conclusion The chemical dot thermometer is useful and reliable for measuring body temperature of orally intubated patients. When measurements of body temperature have important consequences for decisions about treatment, clinicians should use an electronic thermometer to confirm measurements made with a chemical dot thermometer.

У даному дипломному проекті був розроблений безконтактний інфрачервоний термометр, для використання у громадських місцях. Перевагами даного пристрою є висока швидкість вимірювання температури, автономність, висока точність вимірювання, невеликі розміри та можливість підключення до турнікетів в громадських місцях. Пристрій починає вимірювати температуру після знаходження тіла в зоні вимірювання, після чого за допомогою мікроконтролера оброблює результат та видає результат на дисплей і дозволяє пройти через турнікет, а при перевищенні температури залишає турнікет закритим та видає звуковий сигнал.
In this diploma project, a non-contact infrared thermometer was developed for use in public places. The advantages of this device are high speed temperature measurement, autonomy, high measurement accuracy, small size and the ability to connect to turnstiles in public places. The device starts measuring the temperature after the body is in the measurement area, then uses a microcontroller to process the result and displays the result and allows it to pass through the turnstile, and when the temperature is exceeded leaves the turnstile closed and beeps.

Abstract:
National guidelines for stroke recommend that all patients entering rehabilitation are screened for mood disturbance using a validated measure. The first half of this thesis presents a literature review of 25 self-report screening measures for the detection of post-stroke distress. A total of 26 studies were identified as meeting the search criteria. Fifteen self-report measures met recommended levels of sensitivity (≥0.80) and specificity (≥0.60) when screening for post-stroke depression. The Hospital Anxiety and Depression Scale (HADS) was the only measure to meet recommended levels of accuracy for post-stroke anxiety. At the commencement of this thesis, the Distress Thermometer (DT) had not been validated among stroke survivors despite being recommended by NICE (2009). The study presented in the second half of this thesis investigates the diagnostic accuracy and clinical utility of the DT and associated Problem List (PL), the Brief Assessment Schedule Cards (BASDEC), and the Yale. Relative to the HADS, the area under the curve (AUC) for the DT was significantly greater than an AUC of 0.50. Cut-off scores of at least 4 and 5 on the DT met recommended levels of sensitivity and specificity when screening for post-stroke depression and anxiety. The accuracy of the BASDEC and Yale was non-significant. Due to a small sample size, these results should be taken with caution. However, this study provides preliminary evidence to support the use of the DT and PL as a holistic and person-centred screening tool for the prevention and recognition of post-stroke distress.

Dissertação para obtenção do Grau de Mestre em Engenharia Biomédica
Since mercury thermometers were banned due to environmental concerns, hospitals started to use electronic thermometers for measuring body temperature. Body temperature can be measured from different body parts, although the least invasive and quickest is preferred and therefore eardrum measurements are frequently taken. However, lately the staff feels that the taken measurements are not accurate. A new purchasing agreement for the purchase of these devices renders a good opportunity to study further the use of these devices at the wards of the university hospital, study their maintenance process, identify what performance is essential for the clinical usage, the parameters that are essential to measure and also identify ear thermometers in the market that can be used for comparative study. Temperature measurements were taken with the help of an infrared ear thermometer, Covidien Genius2, in its calibration blackbody device at the R&D department of the Huddinge Hospital in order to verify accuracy claims. This data were compared against other studies and measurements of other infrared ear thermometers devices, the Braun ThermoScan Pro 4000 and also a digital contact thermometer, Welch Allyn Suretemp Plus, applied to different body sites. Informal meetings also took place in order to get more information about the devices and to know where they were used and repaired. It was found that Genius2 measured temperature accurately when compared with a blackbody radiator. Regarding the Braun, it showed an accurate estimate of core temperature in comparison to invasive pulmonary artery catheter thermometry. Electronic tympanic thermometers proved to be a good replacement for conventional methods of thermometry. However, preventive maintenance should occur more often, since the devices are very fragile. Tympanic thermometers are generally very accurate instruments. Most likely, problems are not related to the thermometers themselves, they are possibly the result of an inadequate understanding of the limitations of ear thermometry.

Abstract:
AbstractImplicit in the idea of measurement is the concept of objectivity. When we measure the temperature using a thermometer, we assume that the measurement we obtain is not dependent on the conditions of measurement, such as which thermometer we use. Any functioning thermometer should give us the same reading of, for example, 75 °F. If one thermometer measured 40 °, another 250 and a third 150, then the lack of objectivity would invalidate the very idea of accurately measuring temperature.

Abstract:
Traditionally, thermometers are calibrated by comparison with reference thermometers, such as standard platinum resistance thermometers in liquid baths. The process is time consuming and costly since an operator is required to adjust the bath temperature and take the readings of the thermometers. The Standards and Calibration Laboratory (SCL), Hong Kong Special Administrative Region recently developed a fully automated calibration system for thermometer calibration which does not require the attention of an operator. The system makes use of a computer to control the bath temperature and take the thermometer readings by using pattern recognition techniques. Optical Character Recognition (OCR) and Liquid Level Recognition (LLR) techniques are employed to take the readings of the digital and liquid-in-glass thermometers respectively. The reading process starts with taking pictures of the display of the thermometer under test by a smart video camera. The images are analyzed by Labview based programmes to find the thermometer readings. The system can be trained to recognize various display formats of the thermometers under test. The images of the display readings are retained for proof checking when a report is produced.

Abstract:
Radiation thermometers constitute a high accuracy class of measurement devices used for the detection and measurement of radiance and radiation temperature emitted by primary standard blackbody cavities and infrared flat plate calibration sources. These primary grade thermometers are employed by standards laboratories and National Measurement Institutes (NMIs) to measure and assess many source radiation temperature output characteristics, including size of source, source emissivity and the output emission passband. Not unlike the best electronic standards used in any measurement discipline, radiation thermometers exhibit measurement changes over time otherwise called drift. Radiation thermometer drift can introduce unfamiliar offsets in the final measurement results without knowledge of the drift behavior. This paper describes a method for quantifying drift and its uncertainty in radiation thermometry based on statistics work published in literature by the former National Bureau of Standards (NBS).

Abstract:
Abstract A blackbody optical fiber thermometer consists of an optical fiber whose sensing tip is given a metallic coating. The sensing tip of the fiber forms an isothermal cavity, and the emission from this cavity is approximately equal to the emission from a blackbody. Temperature readings are obtained by measuring the spectral radiative flux at the end of the fiber at two wavelengths. The ratio of these measurements is used to infer the temperature at the sensing tip. However, readings from blackbody optical fiber thermometers are corrupted by self-emission when extended portions of the probe are exposed to elevated temperatures. This paper describes an alternative approach for using blackbody optical fiber thermometers that avoids the problems due to self-emission. In the alternative approach, an inverse method incorporating spectral measurements is used to reconstruct the temperature profile along the fiber. A genetic algorithm is used as the basis for the inversion method.

Abstract:
In Singapore, there is an increasing demand for calibration of Industrial Radiation Thermometers (IRTs), and the number of calibration laboratories providing calibration services from -20 °C to 900 °C has surged in recent years, especially for the calibration laboratories providing calibration when the emissivity setting of the thermometer is less than 1. Nevertheless, the spectral response of these IRTs are usually from 8 to 14 μm and they are not adapted properly for the wider temperature range especially at emissivity setting of 0.95. A typical IRT was chosen, studied and investigated for this purpose, while circulating among 7 participating laboratories. The IRT was calibrated and characterized by evaluation of repeatability, reproducibility, stability and possible drift, before and after each measurement at each of the laboratory. The reference temperature, Tref, was obtained by using reference thermometer such as Platinum Resistance Thermometer (PRT), thermocouple or radiation thermometer at the corresponding blackbody source temperatures. The measurements were performed with IRT emissivity settings equal to 0.95 and 1.0, respectively. The reference temperature for emissivity setting equal to 0.95, T0.95, was determined by using a software developed by NMC. The final reference values for both emissivity setting of 0.95 and 1.0 were calculated based on the average of the calibration results before sending to and after receiving from each participating laboratory. From analysis of the reference values and drift study, it is found that this IRT is more suitable for applications up to 200 °C due to small variance of the repeatability and reproducibility. On the other hand, even though a wider temperature range (- 30 °C to 900 °C) can be found from the instrument specification, larger variance of the repeatability, reproducibility and drift are observed in the temperature range above 200 °C from this study. Among the 7 participating laboratories, only one laboratory shows inconsistency result with the reference value at one test point and all the other laboratories have demonstrated consistent differences with the comparison reference values in association with their measurement uncertainties. Some of the laboratories need to improve their measurement uncertainties in the near future.

Abstract:
The aim of this technical report is to provide detailed information about the long-term stability of the thermometer ASL F200 (WIKA Instruments Limited [1]) that is used as temperature reference to calibrate other temperature sensors in the Laboratory of Building Energy and Indoor Environment at Aalborg University – Department of the Built Environment [2]. This ASL F200 thermometer is regularly sent for recalibration at the “Temperature Laboratory” of the Danish Technological Institute, which is a National Reference Laboratory [3]. In this report, the stability of the thermometer is assessed as the difference in the temperature reading of the instrument at a specific temperature over time. The latter is calculated as the yearly deviation (or stability) in between consecutive recalibrations, which is equivalent to the difference in the calibration correction term in between two consecutive recalibrations divided by the elapsed time in between these two consecutive recalibrations. The long-term stability of the ASL F200 thermometer is only assessed here for the first channel “Chan 1” of the instrument. All calculations of this technical report are based on calibrations reports from the National Reference Laboratory of the Danish Technological Institute [3]. The main results of those calibration reports can be found in the Appendix at the end of this document.
