由于稳定使用高排放压力计量剂量吸入器 (pMDIs),吸入器的碳足迹增加. 转向非推进剂吸入器 (NPI) 可以显著减少温室气体排放.
科学领域:
- 环境科学环境科学
- 公共卫生 公共卫生
- 药物经济学 药物经济学
背景情况:
- 压力计量剂量吸入器 (pMDIs) 由于其温室气体 (GHG) 推进剂,对医疗保健的碳足迹做出了重大贡献.
- 与pMDIs相比,非推进剂吸入器 (NPI) 的环境影响较低.
- 减少pMDI的使用是减缓医疗保健部门气候变化的关键策略.
研究的目的:
- 分析德国在2013-2022年间的吸入器发行趋势.
- 为了估计与吸入器使用相关的碳足迹 (CF).
- 量化通过增加NPI的使用来实现的潜在温室气体节约.
主要方法:
- 分析德国法定医疗保险 (2013-2022) 的发放数据.
- 对pMDIs (HFC-134a,HFC-227ea),DPI和SMI的年度分发份额和CF估计的计算.
- 基于NPI利用率的增加,开发两个情景来预测潜在的温室气体节约.
主要成果:
- 吸入器发放量增加了14% (2013-2022年),但没有显著转向NPI (2022年52%的NPI).
- 与吸入器相关的CF总量在2022年上升了14%,达到525 kt CO2eq,pMDIs占CF的95%以上.
- 一个NPI使用率为85%的场景预计每年CF减少55% (288 kt CO2eq).
结论:
- 吸入器相关的CF已经上升,这是由于持续使用pMDI,尽管气候中立目标.
- 通过向NPI过渡,有显著的温室气体减排潜力.
- 促进气候友好型吸入器的临床实践变化是必要的和可行的,在其他欧洲国家也可能得到应用.

Respiratory Capacities
One key metric is the Inspiratory Capacity (IC), which represents the maximum amount of air that can be inhaled with full effort. IC is calculated by summing the tidal volume and inspiratory reserve volume, typically ranging from 2.4 to 3.6 liters.
The Functional Residual Capacity (FRC) represents the air in the...

Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...
