A.
Maintaining oxygen saturation above 95%<\/p>\n\n\n\n
B.
Correcting underlying lung pathology<\/p>\n\n\n\n
C.
Relieving shortness of breath<\/p>\n\n\n\n
D.
Preventing complications of hypoxia<\/p>\n\n\n\n

Preventing complications of hypoxia<\/strong><\/p>\n\n\n\n In COPD, hypoxemia, or low blood oxygen levels, is a common issue due to impaired gas exchange in the lungs. Severe hypoxemia can lead to various complications, including cardiovascular stress, confusion, decreased exercise tolerance, and worsening of respiratory function. Oxygen therapy is crucial in preventing these complications and improving the client’s overall well-being.<\/p>\n\n\n\n 1. Preventing Complications of Hypoxia:<\/strong> 2. Maintaining Oxygen Saturation Above 95%:<\/strong> 3. Correcting Underlying Lung Pathology:<\/strong> 4. Relieving Shortness of Breath:<\/strong> In summary, oxygen therapy in COPD is primarily indicated to prevent the complications of hypoxia, rather than to achieve specific oxygen saturation levels or to treat the underlying disease directly.<\/p>\n","protected":false},"excerpt":{"rendered":" A client with chronic obstructive pulmonary disease (COPD) presents with severe dyspnea and hypoxemia.

Oxygen therapy helps to increase the amount of oxygen available in the blood, thus preventing the adverse effects of hypoxia. When oxygen levels fall too low, it can lead to serious health issues such as pulmonary hypertension, right-sided heart failure (cor pulmonale), and increased risk of respiratory infections. By providing supplemental oxygen, these risks are mitigated, improving the patient’s quality of life and reducing the likelihood of exacerbations.<\/p>\n\n\n\n
While maintaining oxygen saturation above 95% can be a goal, it is not always practical or necessary for all COPD patients. The primary objective of oxygen therapy is to alleviate symptoms of hypoxemia and prevent complications rather than strictly achieving a specific oxygen saturation target.<\/p>\n\n\n\n
Oxygen therapy does not address the underlying lung pathology of COPD. It is a supportive measure that helps manage symptoms rather than a treatment for the disease itself.<\/p>\n\n\n\n
While oxygen therapy can help relieve shortness of breath by improving oxygen levels in the blood, its primary indication is to prevent the complications associated with severe hypoxia. Relief of dyspnea is a secondary benefit of providing adequate oxygenation.<\/p>\n\n\n\n
