This survey is being conducted through the Department of Biomedical Engineering at The Johns Hopkins University. We are a group of graduate students at The Johns Hopkins Center for Bioengineering Innovation and Design (CBID) working to improve the standard of care within pulmonology. Your experiences and input will aid in designing new methods of portable oxygen therapy in order to better meet the needs and lifestyles of users.

By completing this survey, you are consenting to be in this research study. Your participation is voluntary and you can stop at any time. The survey is expected to take approximately 15 minutes. Please complete the survey in one sitting, as you will not be able to save and return to your responses once submitted. All responses will remain anonymous and will only be shared for research purposes.
