Removal of this proven oral system may need to be evaluated, and further comparison studies should be conducted before the tympanic thermometer is unconditionally embraced as the more accurate of the two. It may be premature to conclude that the oral thermometer is not as accurate as the tympanic thermometer. Body temperature varies slightly, from 0.25° to 1.1° C (0.5° to 2.0° F), throughout the day temperature is lowest in the early morning and highest in the late afternoon. For example, an individual who is over 70 years old may have a lower. However, what is considered a normal body temperature can vary by one degree based on age, race, and other factors. Should I treat a fever When you or your child is sick. The normal oral temperature for a resting, healthy adult is about 98.6☏ (37☌). Oral temperature of 100 F (37.8 C) or higher Armpit temperature of 99 F (37.2 C) or higher. Thus, ear thermometry should not be used in situations where body temperature. A fever is defined as a body temperature above 100.4☏ (38.3☌). They can be used to take temperature readings in the mouth, rectum, or armpit. The normal oral temperature of 37° C (98.2° F) is merely an average. Measuring Temperature with Infrared Tympanic Thermometers versus Oral. Despite published results that infrared thermometers provide readings closer to core temperature than oral thermometers, the oral thermometer registered higher in 69% of the subjects. Digital thermometer Digital thermometers work by using heat sensors that determine body temperature. The study question asked was: Is there a clinically statistical difference between the measures of the two instruments? A statistically significant difference was found between the readings of the two instruments. Current studies demonstrate that tympanic thermometers give presumably higher temperature readings than do oral thermometers. After the use of tympanic thermometers replaced the use of oral thermometers at the Veterans Affairs Medical Center in Memphis, the nursing staff initiated a comparison study of the two instruments, monitoring 160 temperature readings. 10.1097/00002800-199903000-00011 Abstract After the use of tympanic thermometers replaced the use of oral thermometers at the Veterans Affairs Medical Center in Memphis, the nursing staff initiated a comparison study of the two instruments, monitoring 160 temperature readings.
