持续长程氧疗(CLTO)广泛用于治疗慢性阻塞性肺病和肺心病(COPD-CP),尽管如此,许多患者的病情仍日趋恶化。因此,判明患者对氧疗的反应性对估价患者预后以及寻找其它治疗方法具有重要意义。作者在过去的研究中发现,COPD-CP 患者吸入浓度为28%的氧48小时后,用放射性核素心室造影技术(NVG)测定其射血分数(EF)的变化及测定进行症状限制性运动负荷试验过程中的最大耗氧量(VO_2peak)可能有助于氧疗效果的判断,并可用来预测患者的生存。作者对此进行了研究。
Continuous Long Range Oxygen Therapy (CLTO) is widely used to treat COPD and COPD, although many patients are still experiencing a deteriorating condition. Therefore, to determine the patient’s responsiveness to oxygen therapy is of great importance to evaluate the prognosis of patients and to find other treatments. In a previous study, we found that COPD-CP patients were challenged with radionuclide ventriculography (NVG) for changes in ejection fraction (EF) 48 hours after inhalation of oxygen at a concentration of 28% and for the determination of symptoms-limiting exercise VO2peak during stress testing may be helpful in determining the effects of oxygen therapy and may be used to predict patient survival. The author studied this.
