考虑室内呼吸暴露风险的人群引流控制策略研究

为明确重大疫情中人群引流控制策略对室内呼吸暴露风险的影响,基于改进的行人动力学模型和呼吸传染概率模型,构建一般室内情况下人群运动多种场景,借助多智能体仿真技术,模拟防护优化策略、流量优化策略和路线优化策略对呼吸暴露风险影响。研究结果表明:室内呼吸暴露风险主要取决于行人总流量、个体停留时间、运动路径规划和污染区域持续时间;在行人社交距离遵循行为方面,个体因必须保持设定的物理距离而形成延滞效应,这会进一步增加暴露于污染区域时间;口罩病原体渗透率越低、空间通风量越大,群体呼吸传染概率越小。

呼吸重症监护室内机械通气相关性肺炎护理对策

目的：分析讨论呼吸重症监护室内机械通气相关性肺炎的临床护理方法。方法：随机选取我院呼吸重症监护室内2014年6月~2015年6月收治治疗的132例机械通气相关性肺炎患者作为观察对象,采用随机数字法将其分成对照组与观察组,对照组选择常规护理方法实施护理,而观察组选择临床护理干预方法实施护理。结果：观察组的临床总满意度为94.74%;而对照组的临床总满意度为76.32%,其中观察组的临床护理满意度明显的比对照组好（P〈0.05）。结论：实施临床护理干预,可使患者生活质量与满意度得到提升,并降低出现机械通气相关性肺炎的概率。

试析呼吸重症监护室内机械通气相关性肺炎(VAP)的护理

目的分析呼吸重症监护室内机械通气相关性肺炎(VAP)的护理措施。方法选择我院自2015年10月至2016年10月期间收治的呼吸重症监护室内机械通气相关性肺炎患者70例,依据护理方法差异性均分两组。接受常规护理的35例患者为参照组,接受综合护理干预的35例患者为研究组,最后对两组患者的护理效果进行统计和总结。结果经不同方法护理后,研究组护理满意度(97.2%)较比参照组护理满意度(77.1%)进行统计,组间数据结果结果经检验后P<0.05。肺炎发生率(2.1%)较比参照组(20.0%)也明显较低,组间数据结果结果经检验后P<0.05。结论呼吸重症监护室内机械通气相关性肺炎(VAP)实施护理干预可使患者的满意度进行提升,临床应用价值存在。

Respiratory Risk Associated with Indoor Air Pollutants in the Form of Settled House Dust

Asthma and allergies are considered by many physicians as being triggered by different substances in the air that people breathe. The lung is the most common site of injury by airborne pollutants. Acute effects, however, may also include non-respiratory signs and symptoms, which may depend upon toxicological characteristics of the substances and host-related factors. The studying of indoor air quality can provide a method for appropriate remedial action. Research suggests that SHD （Settled House Dust） may be a significant source for indoor exposure to different substances. This research study consisted of sampling dust from homes in different area codes. The dust samples were collected from August 2006 thru March 2007 and analyzed using GC/MS （Gas Chromatography/Mass Spectrometry）. The purpose of this research study will display how sampling household dust is a powerful tool for identifying chemicals that contribute to poor indoor air quality.
