BENEFITS OF AMBULATORY OXYGEN IN HYPOXEMIC COPD PATIENTS

本子项目是利用由NIH/NCRR资助的中心赠款提供的资源的众多研究子项目之一。子项目和研究者（PI）可能已经从另一个NIH来源获得了主要资金，因此可以在其他CRISP条目中表示。列出的机构是中心的，不一定是研究者的机构。这是一项针对100名低氧血症COPD患者的多中心随机试验，比较使用轻型动态供氧系统与便携式电子气瓶系统的生理和临床益处。本研究结果将为低氧血症COPD患者的临床管理提供科学依据。它还将阐明对更昂贵的门诊氧气治疗的需求，并为技术发展提供激励，这将不可避免地降低这种治疗的成本。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. This is a multicenter randomized trial in 100 hypoxemic COPD patients comparing the physiologic and clinical benefits of utilizing lightweight ambulatory oxygen systems versus portable E-cylinder systems. The results of this investigation will provide a scientific foundation for the clinical management of hypoxemic COPD patients. It will also clarify the need for more expensive ambulatory oxygen therapy and provide incentive for technologic developments that will inevitably reduce the cost of this therapy.
