About

This is an international, mulitcentre, observational, prospective study into Peak Inspiratory Flow in COPD patients that aims to: A) Determine the prevalence of suboptimal Peak Inspiratory Flow (PIF) and inadequate inhaler choice and assess the baseline characteristics of these groups. B) Assess the clinical role of PIF and inhaler choice in predicting COPD exacerbations and symptom burden. C) Assess the variability and correlation of PIF with other lung function measurements and CAT score in stable COPD. It is a 12 month study comprising one baseline assessment and 2 follow-up visits at 6 and 12 months.
