A TRIAL TO COMPARE TWO METHODS OF DELIVERING OXYGEN TO COPD PATIENTS

该子项目是利用NIH/NCRR资助的中心赠款提供的资源的许多研究子项目之一。子项目和研究者（PI）可能从另一个NIH来源获得主要资金，因此可以在其他CRISP条目中表示。所列机构为中心，不一定是研究者所在机构。我们正在招募需要补充氧气的COPD患者，他们通过E-气瓶接受便携式氧气系统。这些受试者将被随机分配继续使用E-气瓶或使用M06 D碳纤维气瓶的小型轻量化便携式氧气系统。主要结果将是确定是否任何一组每周使用更多的氧气时间。

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. We are recruiting COPD patients requiring supplemental oxygen who receive their portable oxygen system by E-cylinders. These subjects will be randomized to either remain using E-cylinders or will be given small, lightweight ambulatory oxygen systems using M06D carbon fiber cylinders. The primary outcome will be to determine whether either group uses oxygen for more hours per week.
