由于使用氟化烃推进剂,使用计量吸入器的哮喘病人每年排放高达140千克CO2e,相当于驾驶量97公里。 Asthma patients using metered-dose inhalers emit up to 140kg CO2e yearly, equivalent to driving 97km, due to HFC propellants.

新加坡科学家发现,使用计量吸入器的哮喘病人因使用氢氟碳化物推进剂而每年释放约140千克二氧化碳当量——相当于驾驶97公里。 Singaporean scientists have found that asthma patients using metered-dose inhalers release about 140kg of CO2 equivalent annually—equivalent to driving 97km—due to hydrofluorocarbon propellants. 干粉吸入器的产量较少,平均每患者121公斤CO2e。 Dry powder inhalers produce less, averaging 121kg CO2e per patient. SingHealth综合诊所根据23 000多名病人提供的数据进行的研究表明,哮喘控制不力导致吸入器使用率提高和排放增加。 Research from SingHealth Polyclinics, based on data from over 23,000 patients, shows poor asthma control leads to higher inhaler use and greater emissions. 专家们敦促更好地自我管理,避免触发,并转向低排放吸入器,以减少健康风险和环境影响。 Experts urge better self-management, trigger avoidance, and a shift to lower-emission inhalers to reduce both health risks and environmental impact. 2025年7月和8月公布了调查结果。 Findings were published in July and August 2025.
