Temperature Measurement Sites

1.6K
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...

Equipments Used to Measure Body Temperature

966
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,...

Here is a stepwise guide to assessing the body temperature at the temporal artery using a temporal artery thermometer
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.  
Step 3: Assess the patient's...

Body Temperature01:25

Body Temperature

912
The body's temperature, measured in degrees, is determined by the balance between heat production and dissipation to the surrounding environment. For instance, if exercising vigorously, the body will produce more heat, causing sweat and dissipating that heat. Despite extreme environmental conditions and physical exertion, the human temperature-control system maintains a constant core body temperature (the temperature of deep tissues, which are the tissues located beneath the skin and other...

Area of Science:

  • Reproductive biology
  • Biomedical engineering
  • Artificial intelligence in healthcare

Background:

  • Human labor onset prediction remains challenging.
  • Mammalian studies suggest body temperature changes precede labor.
  • This phenomenon has not been extensively studied in humans.

Purpose of the Study:

  • Investigate continuous body temperature changes in pregnant women.
  • Determine if temperature changes correlate with hormonal status.
  • Develop a deep learning model for labor onset prediction.

Main Methods:

  • Continuous skin temperature data collected using a wearable smart ring from 91 pregnant women.
  • Steroid hormone levels analyzed in a subset of 28 pregnancies.
  • An autoencoder long short-term memory (AE-LSTM) deep learning model applied for prediction.

Main Results:

  • Temperature patterns linked to urinary hormones and labor type.
  • Spontaneous labors showed distinct hormonal profiles and more stable circadian rhythms.
  • AE-LSTM model predicted labor onset with an average error below 2 days, achieving 79% accuracy within a 4.6-day window 7 days prior.

Conclusions:

  • Continuous skin temperature is a reliable indicator of labor progression and hormonal shifts.
  • Deep learning models utilizing temperature data offer promising clinical applications for pregnancy management.
