Experimental: 1
This study will examine the hypothesis that iloprost maintains and improves ventilation perfusion matching in patients with COPD as reflected by 1) a constant or reduced alveolar to arterial O2 difference as calculated from the measured arterial blood gases obtained before and after iloprost administration, 2) an improvement in the lung diffusing capacity for carbon monoxide that occurs in the absence of a change in spirometry, 3) an improvement in the ventilatory equivalent for oxygen and CO2 measured by expired gas analysis. It is anticipated that a positive result in this pilot study would lead to a larger long-term study examining the effect of iloprost on gas exchange, exercise tolerance and quality of life in patients with COPD. |
