概括
使用红外热学 (IRT) 建立了标准化的眼睛表面温度 (OST) 测量协议. 温度变化速率 (RTC) 是一个更敏感的指标,具有6秒的闪间隔 (IBI) 和平均值,提高了临床诊断的重复性.
科学领域:
- 眼科医生 眼科 眼科
- 医疗成像医学成像
- 生物物理学的生物物理.
背景情况:
- 眼表面温度 (OST) 评估对于诊断各种眼睛疾病至关重要.
- 目前的测量协议缺乏标准化,导致临床实践中的不一致性.
- 红外热学 (IRT) 为OST评估提供了一种非侵入性方法.
研究的目的:
- 建立使用红外热学 (IRT) 的标准化眼睛表面温度 (OST) 测量协议.
- 提高OST测量的一致性,可靠性和翻译适用性.

01:14Temperature Measurement Sites
3.2K
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...

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.
