COPD is a common but irreversible disease. Nevertheless, patients with COPD can maintain good quality of life through psychological resilience and effective self-management. However, limited studies have investigated the relationship between self-management behaviors and resilience in patients with COPD. Thus, the present study aimed to determine the factors associated with self-management behaviors and resilience among patients with COPD. ⋯ This study revealed that self-management and psychological resilience were positively correlated and associated in our linear regression model. Future work may focus on finding the causative relationship between self-management and resilience among patients with COPD.

Mechanical insufflation-exsufflation (MI-E) devices are used to improve airway clearance in individuals with acute respiratory failure. Some MI-E devices measure cough peak flow (CPF) during MI-E to optimize pressure adjustments. The aim was to compare CPF and effective cough volume (ECV: volume expired/coughed > 3 L/s) measurements between 4 MI-E devices under simulated conditions of stable versus collapsed airway. ⋯ CPF values differed significantly across MI-E devices, highlighting limitation(s) of using only CPF values to determine cough effectiveness. In simulated of airway collapse, CPF increased at the mouth, whereas it decreased at the tracheal level.
