These were subjective perceptions of quality of life, relationships with others, functional abilities in life activities, and changes in life since the use of transtracheal oxygen. These topic areas were selected after a review of literature related to COPD and quality of life.
Another interesting pattern which arose involved the failure to name the transtracheal oxygen device by subjects.
The subjects often mentioned that transtracheal oxygen made it easier to be active even if only in their own home.
Instead they referred to the transtracheal oxygen catheter as "it," "the thing" or obscurely as "you know." A 65-year-old retired salesman said, "The last time I had this out, was when I put it in." Another 69-year-old homemaker remarked, "It seems like this thing gets clogged and I clean it and uh it's still, it still feels clogged."
All of the subjects were able to care for the transtracheal oxygen catheter.
