Which factor could contribute to a patient's discomfort with using supplemental oxygen at home?

A lack of education about the benefits of oxygen can lead to discomfort for patients using supplemental oxygen at home. When individuals do not understand how supplemental oxygen can improve their quality of life, manage their symptoms, or enhance their overall health, they may be resistant to using it. This misunderstanding can create anxiety or fear about the implications of using oxygen therapy, leading to discomfort in adopting such a necessary treatment.

In contrast, those with a good understanding of COPD management would likely be more comfortable using supplemental oxygen, as they recognize its role in their treatment. Low self-esteem regarding health may also affect a person's attitude toward oxygen therapy, but it is more about their self-perception than a direct lack of understanding. Lastly, physical limitations that prevent oxygen use would directly hinder the application of oxygen therapy but do not contribute to psychological discomfort regarding its use. Thus, the educational gap plays a pivotal role in the patient’s experience and acceptance of supplemental oxygen therapy.
