Equipments Used to Measure Body Temperature01:13

Equipments Used to Measure Body Temperature

1.4K
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 - Temporal Artery

780
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 Sites

2.5K
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

1.0K
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 - Rectal01:27

Assessing Body Temperature - Rectal

8.3K
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 - Axilla01:14

Assessing Body Temperature - Axilla

868
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...

Area of Science:

  • Agricultural Science
  • Veterinary Medicine
  • Sensor Technology

Background:

  • Accurate cattle body temperature measurement is crucial for disease detection and herd health management.
  • Environmental factors like wind, temperature, and humidity can significantly impact infrared thermography (IRT) readings.
  • Existing methods may lack accuracy or be influenced by external conditions.

Purpose of the Study:

  • To develop a sensitive and accurate method for cattle body temperature measurement using a multi-sensor architecture.
  • To investigate and mitigate the influence of environmental factors and animal movement on IRT measurements.
  • To enhance the reliability and consistency of non-invasive temperature monitoring in cattle.

Main Methods:

  • Utilized a multi-sensor architecture combining infrared thermography (IRT), an anemometer, and a humiture meter.
  • Implemented signal processing techniques to remove IRT frames affected by airflow and animal movement (frame difference method).
  • Developed a calibration method to reduce the impact of ambient temperature and humidity on IRT results.

Main Results:

  • Achieved a mean difference of 0.04 °C and a standard deviation of 0.10 °C between IRT and rectal reference temperatures.
  • Demonstrated substantial improvement in measurement consistency between IRT and reference temperatures.
  • Obtained a root-mean-square error (RMSE) of 0.74 °C, indicating high accuracy despite using a small IRT sensor.

Conclusions:

  • The proposed multi-sensor system with advanced data processing provides a sensitive and accurate method for cattle body temperature measurement.
  • The system effectively compensates for environmental variables and physical disturbances, enhancing the reliability of IRT.
  • This approach offers a practical and accurate solution for non-invasive temperature monitoring in livestock management.
