Assessing Body Temperature - Oral01:14

Assessing Body Temperature - Oral

770
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...

Temperature Measurement Sites01:14

Temperature Measurement Sites

1.8K
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 - Temporal Artery01:19

Assessing Body Temperature - Temporal Artery

584
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 - Rectal01:27

Assessing Body Temperature - Rectal

4.6K
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 - Tympanic membrane01:14

Assessing Body Temperature - Tympanic membrane

610
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:

  • Medical Science
  • Clinical Research
  • Physiology

Background:

  • Oral temperature assessment is common in medical practice, yet normal ranges are poorly defined.
  • Establishing precise normal temperature ranges is crucial for accurate clinical interpretation.

Purpose of the Study:

  • To determine normal oral temperature ranges by age, sex, height, weight, and time of day.
  • To develop individualized normal temperature ranges for adult outpatients.

Main Methods:

  • A cross-sectional study analyzed over 600,000 outpatient encounters with temperature measurements.
  • The LIMIT algorithm filtered encounters to exclude diagnoses affecting temperature distribution.
  • Mixed-effects modeling identified factors influencing normal oral temperature.

Main Results:

  • Over 35% of encounters were excluded; infectious diseases and type 2 diabetes were primary reasons.
  • Individual factors (age, sex, height, weight, time of day) explained up to 25.52% of temperature variability.
  • Mean normal oral temperature did not reach 37°C; upper 99th percentiles varied widely (36.81°C to 37.88°C).

Conclusions:

  • Normal oral temperature exhibits expected variations based on individual characteristics.
  • Individualized normal temperature ranges can be established, enhancing clinical utility.
  • Further research is needed to determine the clinical significance of temperatures outside these established ranges.
