The carbon footprint of devices to deliver inhaled respiratory medications has come into focus as climate change has been identified as a worldwide emergency. Metered dose inhalers (MDIs) contain hydrofluorocarbons that have significant global warming potential compared to dry powder inhalers (DPIs) and soft mist inhalers (SMIs), which do not use a propellant gas. A 12-month pharmacy inpatient dispensing audit demonstrated that inpatient MDI use significantly outweighed that of DPIs and SMIs and accounted for approximately 99% of inhaler-related greenhouse gas emissions at our hospital.
随着气候变化被确定为全球性紧急事件，用于输送吸入式呼吸药物的设备的碳足迹已成为焦点。计量吸入器 (MDI) 含有氢氟碳化物，与不使用推进剂气体的干粉吸入器 (DPI) 和软雾吸入器 (SMI) 相比，其全球变暖潜能值显著更高。一项为期 12 个月的药房住院患者配药审计表明，住院患者 MDI 的使用量明显超过 DPI 和 SMI，占我们医院与吸入器相关的温室气体排放的约 99%。
