What method should a nurse use to administer continuous oxygen therapy to a client with emphysema to avoid depressed ventilation?

• A. At a low flow rate
• B. Through nasal cannula
• C. With humidification
• D. Cooled

Answer: (A)

Administering continuous oxygen therapy to a client with emphysema should be done at a low flow rate to avoid the risk of depressing the patient’s ventilation. In patients with chronic obstructive pulmonary disease (COPD) like emphysema, the respiratory drive often relies on low levels of oxygen rather than elevated levels of carbon dioxide. If high concentrations of oxygen are provided, it may suppress the client’s ability to breathe effectively, leading to potential respiratory failure. Using a low flow rate ensures that oxygen is delivered in a way that increases oxygen saturation without completely eliminating the hypoxic drive that some individuals have adapted to. This careful balance is crucial to maintain adequate respiration in patients with compensatory physiologic mechanisms. While the other methods mentioned, such as using a nasal cannula, with humidification, or using cooled oxygen, may have their own benefits or applications in different contexts, the most direct approach to prevent the risk of depressed ventilation in these patients is to carefully regulate the oxygen flow rate.
