概括

转换为E气的氧化 (N2O) 显著减少了医疗机构的废物和成本. 这种N2O输送的变化减少了强大的温室气体排放,而不会影响患者的护理.

科学领域:

环境科学环境科学
医学麻醉学医学麻醉学

背景情况:

像氧化 (N2O) 这样的吸入麻醉剂是医疗保健中的重要温室气体排放者.
由于N2O的环境半衰期长,功效低,因此需要大量的储存量,从而增加泄漏潜力.
斯坦福医疗保健 (SHC) 分析了N2O排放量,以减少废物.

研究的目的:

为了量化N2O污染在SHC.
评估在门诊外科手术中心使用E-气储存和输送N2O的有效性,以减少全系统的排放.

主要方法:

第一个阶段:在SHC分析了2022年N2O采购和交付数据 (Epic EHR).
第二阶段:在A校区进行试点研究,使用电子气,每周称重并比较5周的交付数据.
第三阶段:在B校区复制方法.

主要成果:

在2022年,购买的N2O (7,436,566.8L) 的90.5%在SHC浪费,耗资57,285.5美元.
在A和B校区的试点研究显示,E气的N2O使用量很小,远远低于三的总和.
电子气的N2O使用与交付数据密切匹配,表明减少了浪费.

结论:

过渡N2O交付从集中储存到照顾点的E气大大减少了废物和成本.
结果支持分析N2O储存系统,并考虑实施E-气以降低医疗保健排放.
减少N2O废弃物有助于实现SHC的目标,即到2030年将范围1和范围2的排放量减少50%.

Carbon-dioxide Fixation

Carbon-dioxide Fixation

Carbon dioxide fixation in prokaryotes enables the assimilation of inorganic carbon into organic molecules, supporting biosynthetic pathways, sustaining ecosystems, and contributing to the global carbon cycle. It also has industrial applications in carbon capture and bioproduct synthesis. Autotrophic organisms rely on this process to utilize CO₂ as a carbon source in diverse environments.The Calvin CycleThe Calvin cycle is the most widespread carbon fixation mechanism, primarily used by...

Inorganic Nitrogen Assimilation

Inorganic Nitrogen Assimilation

Nitrogen is an essential element in biological systems, forming a crucial component of proteins, nucleic acids, and other cellular constituents. Many bacteria and archaea acquire nitrogen in the form of nitrate (NO₃⁻) or ammonia (NH₃), which are then assimilated into biomolecules through specific enzymatic pathways.Assimilatory Nitrate ReductionWhen nitrate enters the cell, it undergoes a two-step reduction process known as assimilatory nitrate reduction. Initially, the enzyme nitrate reductase...

Microbes and Climate Change

Microorganisms are pivotal agents in Earth's biogeochemical cycles, significantly influencing climate dynamics through their metabolic activities. These microbes modulate the levels of key greenhouse gases by both contributing to and helping mitigate climate change.Microbial Contributions to Greenhouse Gas EmissionsRising global temperatures accelerate microbial metabolism, which, in turn, speeds up the decomposition of organic matter. This process releases carbon dioxide (CO₂) through...
