Assessing Body Temperature - Temporal Artery01:19

Assessing Body Temperature - Temporal Artery

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 forehead...
Assessing Body Temperature - Rectal01:27

Assessing Body Temperature - Rectal

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...
Temperature Measurement Sites01:14

Temperature Measurement Sites

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 - Oral01:14

Assessing Body Temperature - Oral

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 - Axilla01:14

Assessing Body Temperature - Axilla

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...
Assessing Body Temperature - Tympanic membrane01:14

Assessing Body Temperature - Tympanic membrane

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...

Summary

The Canadian Humidex index often underestimates indoor workplace dangers and inaccurately predicts thermal comfort. A comprehensive thermal environment assessment requires considering all six key thermal sensation parameters.

Area of Science:

  • Environmental Science
  • Occupational Health
  • Building Science

Background:

  • Reliable thermal environment assessment requires six parameters: air temperature, velocity, humidity, radiant temperature, metabolic rate, and clothing properties.
  • Simpler indices like Canadian Humidex are increasingly used for quick thermal assessments, despite limitations.

Purpose of the Study:

  • To compare the reliability of the Canadian Humidex index against rational, heat-balance-based methods for indoor and outdoor thermal environments.
  • To evaluate the accuracy of Humidex for predicting indoor thermal comfort and workplace dangers.

Main Methods:

  • Comparison of assessments using the Canadian Humidex index versus International Standards-based rational methods.
  • Analysis conducted under hot stress conditions, both indoors and outdoors, followed by indoor comfort prediction.

Main Results:

  • The Canadian Humidex index frequently underestimates the severity of indoor workplace thermal conditions.
  • Humidex demonstrates poor reliability in predicting indoor thermal comfort.

Conclusions:

  • The Canadian Humidex index is unreliable for assessing indoor thermal environments and predicting comfort.
  • Rational methods considering all six thermal sensation parameters are superior for accurate thermal environment evaluation.
