Suboptimal peak inspiratory flow rate (PIFR) is highly prevalent in chronic obstructive pulmonary disease (COPD) patients owing to the mismatch of their own PIFR with the corresponding inhaler-device resistance. This study aimed to evaluate aerosol drug-delivery and short-term clinical outcomes of suboptimal PIFR in COPD subjects.

慢性阻塞性肺疾病中次优吸气峰流速的气溶胶给药和短期临床结果

由于他们自己的 PIFR 与相应的吸入器装置阻力不匹配，次优吸气峰流速 (PIFR) 在慢性阻塞性肺病 (COPD) 患者中非常普遍。本研究旨在评估 COPD 受试者中次优 PIFR 的气溶胶给药和短期临床结果。
