Hemodynamic Response to Oxygen Therapy in Chronic Obstructive Pulmonary Disease

摘要: At six centers, 203 patients with stabilized hypoxemic chronic obstructive pulmonary disease were evaluated hemodynamically during a continuous or 12-hour oxygen therapy program. Neither program resulted in correction near-correction of the baseline hemodynamic abnormalities. The group did show improvement vascular resistance, arterial pressure, and stroke volume index. resistance was associated improved cardiac function, as evidenced by an increase exercise nocturnal showed stable variables. For both groups, changes mean artery pressure first 6 months subsequent survival after adjustment for association pressure. Continuous can improve abnormalities hypoxic disease. response to this treatment is predictive survival.
