Prospective Study Comparing Different Modalities of Oxygen Delivery During Assessment of Functional Exercise Capacity
Completed · Not applicable
Conditions studied: COPD
In brief
Objectives: The objective of this study is to determine if any differences exist between the varying modes of portable oxygen delivery systems including liquid oxygen, a portable concentrator, portable devices filled at home from a concentrator, and medical grade compressed oxygen (either an M6 size or D size cylinder). Hypothesis: Patients who are prescribed LTOT will show similar physiologic responses to exercise when using differing modalities of portable oxygen delivery systems.
