Assessing Body Temperature - Temporal Artery01:19

Assessing Body Temperature - Temporal Artery

1.5K
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...

Quantifying Heat02:46

Quantifying Heat

64.3K
Thermal Energy Microscopically, thermal energy is the kinetic energy associated with the random motion of atoms and molecules. Temperature is a quantitative measure of “hot” or “cold”, which depends on the amount of thermal energy. When the atoms and molecules in an object are moving or vibrating quickly, they have a higher average kinetic energy (KE) (or higher thermal energy), and the object is perceived as “hot”, or it is described as being at a higher temperature. When the...

Hot Weather Concreting01:20

Hot Weather Concreting

346
Concreting at elevated temperatures accelerates the hydration process, leading to quicker setting but potentially reducing the long-term strength of the concrete structure. Additionally, low air humidity fosters rapid moisture loss from the concrete, resulting in reduced workability, pronounced plastic shrinkage, and a higher likelihood of crazing.
Mitigating the heat increase in concrete can be economically achieved by shading aggregate stockpiles to prevent heating from solar radiation,...

Assessing Body Temperature - Oral01:14

Assessing Body Temperature - Oral

1.9K
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

14.1K
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...

Factors Influencing Heart Rate01:30

Factors Influencing Heart Rate

7.2K
The heart rate, or pulse rate, is a vital indicator of cardiovascular health. It reflects the number of times the heart beats per minute. Various physiological and environmental factors influence heart rate, increasing or decreasing cardiac output. Understanding these factors is crucial for assessing heart function and identifying potential health issues.
Let us explore the significant factors affecting heart rate, including age, body temperature, posture, acute pain, chemical influences,...

    Area of Science:

    • Environmental Physiology
    • Sports Medicine
    • Exercise Science

    Background:

    • Existing guidelines for preventing heat injury in runners are derived from laboratory studies, which may not accurately represent actual road race conditions.
    • Previous research has not fully quantified the impact of solar radiation on core body temperature during outdoor running events.

    Purpose of the Study:

    • To evaluate the effect of solar radiation on rectal temperature in runners during road races.
    • To develop evidence-based, color-coded guidelines for heat stress risk during running competitions.

    Main Methods:

    • Utilized a novel, portable heat stress monitor to measure physiological responses in runners.
    • Compared rectal temperature under conditions with and without direct solar radiation exposure during actual road races.

    Main Results:

    • Direct solar radiation was found to elevate rectal temperature in runners compared to non-sun conditions.
    • Established temperature thresholds for low risk (below 18°C / 64°F) and unsafe race conditions (above 28°C / 82°F).

    Conclusions:

    • Current laboratory-based heat injury prevention guidelines may be insufficient for real-world running scenarios.
    • Proposed color-coded guidelines based on environmental temperature and solar radiation can enhance runner safety during races.
