Background: Low peak inspiratory flow rate (PIFR) (<60 L/min) among patients with chronic obstructive pulmonary disease (COPD) may result in ineffective medication inhalation, leading to poor bronchodilation. Objective: The objectives of this analysis were to evaluate the prevalence of low PIFR at the time of discharge from a COPD-related …
