Question

Quizplus · Accepted Answer

Emphysema is a type of chronic obstructive pulmonary disease (COPD) that causes damage to the air sacs in the lungs, making it difficult to exhale normally. This often results in the need for supplemental oxygen to be carried with the patient at all times. Chronic bronchitis and asthma may also cause difficulty breathing, but typically do not require the use of supplemental oxygen on a permanent basis. Chronic allergic reactions are not typically associated with the need for supplemental oxygen.
