cerumen occlusion lowers infrared tympanic membrane Temperature Measurement
Academic Emergency Medicine, 1995Co-Authors: David Doezema, Margaret Lunt, Dan TandbergAbstract:OBJECTIVE: To examine the effect that cerumen occlusion of the ear canal has on infrared tympanic membrane Temperature Measurement. METHODS: A prospective, randomized, single-blind human study was carried out in a university hospital observation unit. The subjects were a convenience sample of human volunteers ages 18 years or older who did not have cerumen occlusion or scarred tympanic membranes. A paraffin-coated human cerumen plug was placed in one randomly chosen ear, and after 20 minutes of equilibration the Temperature of each ear was measured with an infrared thermometer. Analysis of the difference in mean Temperature between the occluded and nonoccluded ears was by Student's paired t-test. RESULTS: Infrared tympanic membrane Temperatures were measured in 43 subjects aged 21 to 58 years. The mean Temperature of the occluded ear canal was 0.3 degrees C lower than that of the opposite ear canal (p = 0.0001, 95% CI 0.16-0.45 degrees C). CONCLUSION: Cerumen occlusion of the ear canal causes underestimation of body Temperature measure by infrared tympanic membrane thermometry.

simultaneous strain and Temperature Measurement using a single fibre bragg grating
Electronics Letters, 2000Co-Authors: Baiou Guan, Hwayaw Tam, Wengheng Chung, Xiaoyi DongAbstract:A new scheme for simultaneous strain and Temperature Measurement using a single fibre Bragg grating is proposed. The Bragg grating was written on the splice joint between two fibres and has two Bragg wavelengths, which show the same strain dependence but different Temperature response and hence can be used for strain/Temperature discrimination.

simultaneous strain and Temperature Measurement using a superstructure fiber bragg grating
IEEE Photonics Technology Letters, 2000Co-Authors: Baiou Guan, Hwayaw Tam, Xiaoming Tao, Xiaoyi DongAbstract:A novel and simple fiber-optic sensor based on a superstructure fiber Bragg grating (SFBG) for simultaneous strain and Temperature Measurement is proposed and demonstrated. The transmission spectrum of the sensor possesses several narrow-band loss peaks situated on the slope of a broad-band loss peak. By measuring the transmitted intensity and wavelength at one of the loss peaks, strain and Temperature can be determined simultaneously. The accuracy of the sensor in measuring strain and Temperature is estimated to be /spl plusmn/20 /spl mu//spl epsiv/ in a range from 0 to 1200 /spl mu//spl epsiv/ and /spl plusmn/1.2/spl deg/C from 20/spl deg/C to 120/spl deg/C, respectively.

accuracy of tympanic Temperature Measurement using an infrared tympanic membrane thermometer
BMC Research Notes, 2013Co-Authors: Gasim I. Gasim, Imad R. Musa, Mohamed T Abdien, Ishag AdamAbstract:During investigation and diagnosis of patients, accurate Temperature Measurement is of great importance. The advantages of tympanic membrane thermometry are speed (Temperature reading available within seconds), safety, and ease of use. The aim of this study was to compare the accuracy of infrared tympanic thermometers in comparison to mercury thermometers in Measurement of body Temperature. Axillary and tympanic Temperature was measured simultaneously in consecutive patients using mercury glass and infrared tympanic thermometers at Omdurman Hospital, Sudan during October 2012. In total, Temperature was measured in 174 patients, 95 of whom (54.6%) were male. The mean (SD) patient age and weight was 33.18 (25.07) years and 52.13 (69.85) kg. There was no significant difference in mean (SD) Temperature Measurement between mercury and infrared tympanic membrane thermometers, 37.29°C (0.91) versus 37.38°C (0.95), P = 0.373, respectively. There was a significant positive correlation between axillary and tympanic body Temperature Measurements (r = 0.697, P < 0.001). The mean difference between the two readings (with limits of agreements) was - 0.093 (−0.20; 0.02) °C. In this study, tympanic membrane thermometry is as reliable and accurate as axillary mercury glass thermometry. Thus, tympanic thermometry can be used in clinical practice, especially in the emergency setting, where ease of use and speed of obtaining the Temperature reading are important.
