Airflow limitation or static hyperinflation: which is more closely related to dyspnea with activities of daily living in patients with COPD?
K Nishimura, M Yasui, T Nishimura, T Oga - Respiratory research, 2011 - Springer
Background Dyspnea while performing the activities of daily living has been suggested to be
a better measurement than peak dyspnea during exercise. Furthermore, the inspiratory …
