Which oxygen device is generally not recommended for long-term use in patients with COPD?

The nonrebreather mask is typically not recommended for long-term use in patients with Chronic Obstructive Pulmonary Disease (COPD) due to its design and the way it delivers oxygen. This type of mask provides a high concentration of oxygen, which can lead to respiratory depression in patients with COPD. These patients often rely on lower levels of oxygen and have an altered respiratory drive, making them sensitive to elevated oxygen levels. Using a nonrebreather mask can potentially suppress their drive to breathe, resulting in inadequate ventilation.

In contrast, other devices like the nasal cannula and Venturi mask offer a more controlled oxygen delivery, allowing for titration based on the patient’s needs, making them suitable for longer-term use in managing COPD. The simple face mask may also deliver a higher concentration of oxygen but is not commonly used for extended periods due to discomfort and potential CO₂ buildup. Thus, the nonrebreather mask is not ideal for maintaining adequate oxygenation over time in COPD patients due to these risks.
