气候变化影响呼吸系统健康. 短期和长期暴露于热量都会对肺功能产生负面影响,较高的温度会导致肺容量明显下降,液产量增加.
科学领域:
- 环境健康 环境健康
- 肺部病理学 肺部病理学
- 气候变化研究 气候变化研究
背景情况:
- 全球气温上升和气候变化导致的温度变化增加对呼吸系统健康构成风险.
- 现有的关于温度对肺功能短期影响的研究是相互矛盾的,长期影响在很大程度上仍然不确定.
研究的目的:
- 研究环境温度对肺功能和呼吸系统症状的短期,中期和长期影响.
- 通过使用详细的暴露数据,在全国代表性人口中分析这些影响.
主要方法:
- 在2016-2018年期间,韩国国家健康和营养检查调查 (KNHANES) 的10,819名参与者的横截面分析.
- 使用高分辨率大气模型估计了个体化的温度暴露.
- 一般化添加模型 (GAM) 和分布式滞后非线性模型 (DLNM) 用于评估不同时间尺度 (滞后日0-14,移动平均30-180天和1-5年) 的影响.
主要成果:
- 短期暴露于高温 (例如29.7°C) 与1秒内强迫呼气体积 (FEV1) 和强迫生命能力 (FVC) 的减少有关,累积效应持续超过14天.
- 长期暴露于热量 (例如5年移动平均值13.7°C) 与FEV1的下降有关,特别是在更高的极端温度下.
- 慢性唾液产生与长期暴露于热量 (移动平均值为1至5年) 有着显著的关联.
结论:
- 短期和长期暴露于热量都会显著损害肺功能.
- 对肺功能的不良影响在更高的环境温度下更加明显.
- 长期暴露于热量也与慢性唾液产生的可能性增加有关.

Requirements for Human Life
Oxygen
Atmospheric air is only about 20 percent oxygen, but that oxygen is a key component of the chemical reactions that keep the body alive, including the reactions that produce ATP. Brain cells are susceptible to a lack of oxygen because they require a...

Factors Affecting Respiration
Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
Critical Guidelines for Assessing Ventilation:
Physical Assessment of the Respiratory Tract I: Health History
Subjective Data
Subjective data provides vital information about the patient's health history and symptoms. This data is typically collected through interviews in which patients describe their experiences, symptoms, and concerns.
Health history and...
Physiological Control of Respiration
Breathing, a seemingly passive process, is regulated by the respiratory center in the brainstem. This center coordinates the involuntary control of respirations, which means it occurs without conscious effort, ensuring a smooth and uninterrupted pattern.
Regulation of Ventilation
The body maintains ventilation by monitoring levels of carbon dioxide (CO2), oxygen (O2), and hydrogen ion concentration (pH) in the arterial blood. Among these factors, the level of CO2 plays a crucial...
