Equipments Used to Measure Body Temperature01:13

Equipments Used to Measure Body Temperature

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

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 - 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 - 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 - 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...
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...

Area of Science:

  • Biomedical Engineering
  • Gynecology
  • Menopause Research

Background:

  • Hot flashes are a common symptom of menopause, significantly impacting quality of life.
  • Objective and accurate measurement of hot flashes is crucial for clinical trials evaluating treatment efficacy.
  • Current methods for hot flash monitoring can be cumbersome or invasive, requiring electrodes and gel.

Purpose of the Study:

  • To design and validate a novel, miniature, ambulatory hot flash recorder.
  • To develop a device that does not require electrodes or gel for hot flash detection.
  • To assess the utility of this recorder as an endpoint in clinical trials for hot flash treatments.

Main Methods:

  • A prototype recorder utilizing a relative humidity sensor was developed.
  • Laboratory studies compared humidity sensor readings with patient event marks and sternal skin conductance.
  • Field testing compared the prototype recorder's humidity data with sternal skin conductance and patient event marks.

Main Results:

  • Laboratory validation demonstrated 100% positive predictive value (PPV), sensitivity, and specificity for the humidity sensor compared to other measures.
  • In field studies, the humidity recorder achieved a PPV of 95.6%, specificity of 95.2%, and sensitivity of 90.9% compared to skin conductance.

Conclusions:

  • The miniature ambulatory hot flash recorder is a reliable and accurate tool for hot flash monitoring.
  • The device's non-invasive nature and high accuracy make it suitable for use in clinical trials.
  • This technology offers a promising new endpoint for evaluating the effectiveness of hot flash interventions.
