we therefore measured hemodynamics , blood gases , and the distributions of ventilation-perfusion ratios ( va/q ) , using the multiple inert gas elimination technique , at baseline and during infusion of pge1 0.02 to 0.04 microgram.kg-1.min-1 in six patients with pulmonary hypertension secondary to ards ventilated with 10 cm h2o positive end-expiratory pressure .
