Assessing Body Temperature - Tympanic membrane01:14

Assessing Body Temperature - Tympanic membrane

1.2K
Assessing tympanic membrane temperature involves using a tympanic membrane thermometer (TMT). Here is a step-by-step guide:
Step 1: Begin by practicing good hand hygiene to prevent the transmission of microorganisms.
Step 2: Turn on the thermometer and wait until the ready sign appears on the screen to ensure accurate measurement.
Step 3: Slide the probe cover in place to prevent cross-contamination.
Step 4: Instruct the patient to tilt their head to the side for comfort and check for cerumen...

Body Temperature01:25

Body Temperature

4.2K
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...

Body Temperature

1.4K
Body temperature reflects the equilibrium between heat production and heat loss within the body. Most heat is generated by metabolically active tissues, particularly the liver, heart, brain, kidneys, and endocrine organs. At rest, skeletal muscles contribute 20–30% of total heat production, but during vigorous exercise, this can increase up to 30–40 times.
The average body temperature is approximately 37°C (98.6°F) and typically ranges from 36.1–37.2°C...

Effects of Temperature on Free Energy02:11

Effects of Temperature on Free Energy

28.2K
The spontaneity of a process depends upon the temperature of the system. Phase transitions, for example, will proceed spontaneously in one direction or the other depending upon the temperature of the substance in question. Likewise, some chemical reactions can also exhibit temperature-dependent spontaneities. To illustrate this concept, the equation relating free energy change to the enthalpy and entropy changes for the process is considered:

Increased Body Temperature

7.5K
A body temperature above  38°C  (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

Area of Science:

  • Medical research
  • Infectious disease diagnostics
  • Thermometry

Background:

  • Current fever monitoring is often limited to intermittent checks.
  • Early and accurate diagnosis of tuberculosis (TB) remains a global health challenge.

Purpose of the Study:

  • To evaluate 24-hour continuous tympanic temperature patterns in febrile patients.
  • To identify characteristic temperature patterns associated with tuberculosis (TB).

Main Methods:

  • An observational study involving 81 undifferentiated fever patients.
  • Continuous 24-hour tympanic temperature recordings using the TherCom device.
  • Analysis and comparison of unique temperature patterns between TB and non-TB patients.

Main Results:

  • Tuberculosis patients displayed a unique temperature pattern: a slow elevation followed by a slow fall.
  • This pattern was observed in 78.5% of TB patients versus 24.52% of non-TB patients.
  • The specific temperature pattern showed significant diagnostic potential.

Conclusions:

  • Continuous tympanic thermometry can reveal distinct fever patterns.
  • The identified slow temperature rise and fall pattern is a potential diagnostic aid for early tuberculosis detection.
  • This method may improve diagnostic accuracy for tuberculosis in febrile patients.
