What is the purpose of oxygen during treatment for emphysema?

The purpose of oxygen during treatment for emphysema is to enhance oxygen availability to tissues. Emphysema causes damage to the alveoli, the tiny air sacs in the lungs where gas exchange occurs, leading to decreased oxygen exchange and lower levels of oxygen in the bloodstream. When individuals with emphysema receive supplemental oxygen, it helps to increase the concentration of oxygen in their blood. This enhanced oxygen delivery is crucial for maintaining bodily functions and supporting the metabolic needs of tissues throughout the body. Improved oxygen availability can also help individuals feel more energized and engaged in daily activities, which may be affected by chronic respiratory issues.

In contrast, other options do not correctly describe the primary purpose of oxygen therapy in this context. For instance, increasing heart rate is typically not a goal of oxygen therapy, as the aim is to improve oxygen saturation rather than stimulate the heart. Calming the body may occur as a secondary effect when patients find relief from hypoxia, but it is not the primary target of oxygen treatment. Similarly, creating a more buoyant state is unrelated to the medical function of oxygen treatment, as it pertains to physical properties rather than therapeutic outcomes in respiratory conditions.
