概括
估计湿球球体温度 (WBGT) 的手机应用与现场设备相对应,但运行更冷. 这种差异影响了热安全活动的修改,特别是在更热的条件下.
科学领域:
- 环境健康 环境健康
- 职业安全 在职业安全.
- 运动医学 运动医学
背景情况:
- 劳动热病是户外工作者,运动员和军人面临的风险.
- 使用湿球球体温度 (WBGT) 监测热应力对于安全至关重要.
- 电话应用程序 (PA) 提供估计的WBGT,但它们与现场设备 (OS) 的准确性尚不清楚.
研究的目的:
- 将来自电话应用程序 (Zelus PA) 的WBGT估计与现场 (OS) 测量进行比较.
- 评估这些差异对活动修改分类的影响.
主要方法:
- 一项为期2个月的观察性研究收集了1056个配对的WBGT测量 (OS与PA).
- 收集了来自美国26所高中的数据,覆盖了各种表面 (人造草,天然草).
- 使用区域活动修改值对WBGT值进行了分类.
主要成果:
- 在PA和OS WBGT测量之间发现了很高的相关性 (r=0.89).
- 平均而言,PA WBGT比OS测量低1°C,在更高的温度下差异较大.
- 在活动修改类别中观察到显著的差异,PA建议修改较少.
结论:
- 虽然相关,但电话应用程序WBGT估计与现场测量有所不同,特别是在更热的条件下.

Temperature Measurement Sites
1.5K
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 - Oral
703
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...

Conduction, Convection and Radiation: Problem Solving
1.1K
There are three methods by which heat transfer can take place: conduction, convection, and radiation. Each method has unique and interesting characteristics, but all three have two things in common: they transfer heat solely because of a temperature difference; and the greater the temperature difference, the faster the heat transfer.
In order to solve a problem related to heat transfer, first of all, the situation needs to be examined to determine the type of heat transfer involved. This could...
