Background: Dynamic hyperinflation, caused by expiratory flow limitation, markedly increases resting end-expiratory lung volume (functional residual capacity) in many COPD patients.
Objective: To determine the impact and duration of impact of CPAP on hyperinflation and airway resistance in patients with stable COPD.
Methods: In a case series, 21 patients underwent CPAP at 8 cm H(2)O for 15 min, then whole-body plethysmography immediately after, and at 15 and 30 min after CPAP.
