Assessing Body Temperature - Temporal Artery01:19

Assessing Body Temperature - Temporal Artery

706
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...

Temperature Measurement Sites01:14

Temperature Measurement Sites

2.3K
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...

Assessing Body Temperature - Rectal

7.1K
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...

Procedural Guide for Assessing Axillary Body Temperature using a Digital Thermometer:
Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...

Equipments Used to Measure Body Temperature

1.2K
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 - Oral01:14

Assessing Body Temperature - Oral

881
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...

Area of Science:

  • Occupational Health
  • Environmental Physiology
  • Biomedical Engineering

Background:

  • Occupational heat exposure poses significant health risks to outdoor workers.
  • Accurate monitoring of core body temperature (CBT) is essential for assessing heat stress.
  • Current methods for measuring CBT can be invasive or impractical in field settings.

Purpose of the Study:

  • To evaluate the accuracy of an algorithm estimating core body temperature (CBT_est) using sequential heart rate and initial CBT.
  • To compare the algorithm's estimated CBT (CBT_est) with gastrointestinal temperature (CBT_gi) measured by ingestible sensors.
  • To determine the algorithm's potential as a practical tool for occupational heat health research.

Main Methods:

  • Data from 35 outdoor agricultural workers (pear and apple harvesters) in Washington State were analyzed.
  • Core body temperature was measured using ingestible sensors (CBT_gi) and estimated using a novel algorithm (CBT_est).
  • Bland Altman methods were employed to assess the agreement between CBT_est and CBT_gi across a work shift.

Main Results:

  • The mean gastrointestinal core body temperature (CBT_gi) was 37.7°C (SD 0.4°C).
  • The overall bias between estimated and gastrointestinal CBT was -0.14°C (±0.76°C).
  • Individual biases ranged from -0.006°C to -0.75°C, indicating good agreement.

Conclusions:

  • The developed algorithm provides a non-invasive method for estimating core body temperature.
  • This algorithm may serve as a practical tool for research on heat stress interventions in occupational settings.
  • The findings support the use of this algorithm for evaluating the effectiveness of strategies to prevent adverse heat health effects in agricultural workers.
