Hemodynamic Effects of Oxygen Therapy in Patients With Acute Exacerbations of Chronic Obstructive Pulmonary Disease: Measurements and Calculations

Hemodynamic parameters, Sa02, and mixed-venous oxygen saturation (SvOJ were measured in all patients once they were monitored as described previously (breathing fractional concentration of oxygen in the inspired gas [FIoJ = 0.21). Those values were taken as the baseline. Then oxygen therapy at an FIo2 sufficient to keep Pa02 above 55 mm Hg was started,…

Hemodynamic Effects of Oxygen Therapy in Patients With Acute Exacerbations of Chronic Obstructive Pulmonary Disease: Materials and Methods

The effects of long-term oxygen therapy in patients with COPD are well known. A decrease in pulmonary hypertension accompanied by an improvement in the quality of life and survival rate of these patients has been reported previously; however, the changes in hemodynamic and oxygen transport variables induced by oxygen therapy in patients during acute exacerbations…
