A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder. Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

Body temperature can be assessed using various devices and measured in Celsius or Fahrenheit. Glass-bulb Thermometer: Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...

Slippery surfaces provide a new way to solve the adhesion problem. This protocol describes how to fabricate slippery surfaces at high temperatures. The results demonstrate that the slippery surfaces showed anti-wetting for liquids and a remarkable anti-adhesion effect on soft tissues at high temperatures.
FAQs
Contact thermometers detect heat through direct physical contact with the measured surface, whereas infrared sensors estimate temperature from emitted thermal radiation without touching it. This difference affects how the measurement is obtained and makes technique important for both approaches. The selected method should match the clinical situation and allow readings to be interpreted alongside the measurement site and surrounding conditions.
Ambient temperature, blood flow, and moisture can alter the measured temperature at an external surface. These influences may produce a localized increase or decrease that does not represent a broader change throughout the body. Recognizing these variables helps clinicians avoid treating a single reading as definitive and supports more reliable comparisons when conditions and measurement technique remain consistent.
Different external sites can reflect different local thermal conditions, so the site must be considered when interpreting a result. A change may arise from localized inflammation, altered peripheral circulation, or a wound or tissue condition rather than a general physiological pattern. Repeating measurements at a consistent site helps distinguish meaningful change from variation caused by where the reading was taken.
A useful procedure begins by selecting either a contact thermometer or an infrared sensor, then applying it consistently to the intended external site. The surrounding conditions, including ambient temperature and moisture, should be considered, and the same site and approach should be maintained for comparison. Results should then be interpreted in relation to localized findings and broader clinical patterns.
In medicine, surface temperature measurement can support fever screening and monitoring of inflammation. It can also help evaluate peripheral circulation and identify thermal changes associated with wounds or other tissue conditions. Its noninvasive nature allows clinicians to assess external thermal patterns without directly disturbing the area, while interpretation must account for local and environmental influences.
Clinicians compare the measurement with the clinical context, the location of the reading, and relevant influencing conditions such as blood flow, moisture, and ambient temperature. A change confined to a wound, tissue region, or peripheral area may suggest a local process, while a broader pattern is more consistent with a generalized thermal change. Standardized measurements improve this distinction over time.
