Expiratory Muscle Strength, Peak Oxygen Consumption and Hyperinflation Predicts Severe Exacerbation in Chronic Obstructive Pulmonary Disease Patients

Expiratory muscle weakness, reduced peak oxygen consumption, diminished exercise capacity, and pulmonary hyperinflation are independent predictors of frequent severe acute exacerbations in patients with COPD. Incorporating these parameters into routine assessments may enhance risk stratification and goal-directed therapies, and potentially reduce hospitalization rates.
