Equipments Used to Measure Body Temperature01:13

Equipments Used to Measure Body Temperature

1.1K
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,...

Assessing Body Temperature - Rectal01:27

Assessing Body Temperature - Rectal

5.9K
Rectal temperature measurement is considered the most precise method for assessing core body temperature and typically registers higher than oral temperature. For adults, the rectal thermometer should be inserted 1 to 1.5 inches into the rectum to obtain the most accurate reading.
Follow these steps for rectal temperature assessment:
Step 1: Perform hand hygiene and don clean gloves to prevent cross-infection.
Step 2: Position the patient in a side-lying position to better visualize the rectal...

Assessing Body Temperature - Temporal Artery

641
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...

Assessing Body Temperature - Oral01:14

Assessing Body Temperature - Oral

810
Here are the steps to accurately measure oral temperature using an electronic thermometer:
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
Step 4:
Instruct the patient to open their mouth and place...

Assessing Body Temperature - Tympanic membrane01:14

Assessing Body Temperature - Tympanic membrane

641
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...

Area of Science:

  • Sports Medicine
  • Biomedical Engineering
  • Environmental Health

Background:

  • Heat-related illnesses (HRI) pose significant global health risks, with core body temperature (CBT) > 40°C indicating severe hyperthermia.
  • Current CBT measurement methods are impractical for dynamic environments due to invasiveness, obstruction, or cost.
  • Noninvasive CBT prediction via wearable technology offers potential for continuous monitoring and early HRI intervention.

Purpose of the Study:

  • To systematically review the efficacy of wearable devices and predictive analytics in estimating CBT for HRI prevention.
  • To identify gaps in current research regarding the integration of individual and environmental factors in CBT prediction algorithms.

Main Methods:

  • A systematic review of 20 studies was conducted, analyzing 25 distinct algorithms for predicting CBT using wearable technology.
  • Studies were evaluated for accuracy and clinical validity in predicting core body temperature.

Main Results:

  • The review found high accuracy in CBT prediction, with 17 out of 18 algorithms meeting clinical validity standards.
  • A significant limitation identified was the infrequent incorporation of individual and environmental data into prediction algorithms.

Conclusions:

  • Wearable technology shows promise for accurate CBT prediction, but algorithms need enhancement.
  • Robust machine learning incorporating diverse data is crucial for developing personalized and reliable CBT prediction algorithms.
  • Integration with existing health systems can improve HRI prevention and clinical decision-making.
