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,...
FAQs
Liquid-based instruments translate thermal expansion into a readable temperature. Thermistors infer temperature from changes in electrical resistance, whereas thermocouples use voltage differences produced by temperature conditions. Infrared systems detect radiation from the body without requiring contact. These distinctions determine whether a device uses direct contact, electrical conversion, or remote sensing.
Calibration helps ensure that the device's measured value corresponds reliably to temperature, while placement determines whether the sensor captures the intended body site. Ambient conditions can also influence readings, particularly when measurements depend on the surrounding environment. Patient factors add further variability, so consistent technique is essential when comparing readings over time.
Contact devices obtain measurements through placement at sites such as the oral cavity, rectum, ear, or skin, whereas noncontact systems detect infrared radiation from the body. Noncontact operation avoids physical placement at the measured site, but ambient conditions can still influence results. The choice should reflect the monitoring context and the need for consistent measurements.
Continuous sensors support ongoing monitoring rather than relying only on isolated temperature readings. This approach can help clinical teams follow changes over time, identify possible fever or hypothermia, and assess responses to treatment. Continuous monitoring is especially relevant in hospital care, where repeated temperature information can support observation of a patient's changing condition.
Begin by choosing a suitable device and measurement site, such as oral, rectal, ear, skin, or noncontact measurement. Apply consistent placement, account for calibration and ambient conditions, and consider patient factors. This workflow improves the comparability of readings used for diagnosis, monitoring, or evaluation of treatment responses.
Repeated temperature data can help identify fever, hypothermia, and possible infection, while also showing whether a treatment response is occurring. The value of a reading depends on reliable measurement conditions, including calibration, placement, ambient environment, and patient factors. Clinicians can therefore use temperature measurements as part of diagnosis and ongoing monitoring.
Temperature measurement devices support care across hospitals, outpatient settings, and home healthcare. In hospitals, continuous sensors or noncontact systems can improve ongoing monitoring; outpatient and home use can provide measurements for clinical assessment and follow-up. Their broader value lies in making temperature data available across different care environments and monitoring needs.
