NCT02105220
The goal of this study is to describe the influence of the chest wall on the respiratory system mechanics in morbidly obese patients and in patients with high intra-abdominal pressure. The effects of increasing and decreasing positive end-expiratory pressure (PEEP) on chest wall and total respiratory system mechanics, lung volumes and gas exchange will be evaluated, both during controlled and assisted mechanical ventilation. Patients will be studied, first, during the acute phase of respiratory failure, when requiring intubation and controlled mechanical ventilation. Then, patients will be evaluated again during weaning from the ventilator to assess the influence of PEEP in assisted ventilation prior to extubation.
NCT00796666
As monotherapy for pulmonary arterial hypertension (PAH) begins to fail additional therapies are introduced. Although co-administration of sitaxsentan and sildenafil is well tolerated the controlled safety/efficacy database of the combination is limited.
