What is the most likely practice to improve patient comfort when nasal congestion persists during CPAP use, aside from pharmacologic options?

• A. Increase heated humidity settings
• B. Turn off humidity completely
• C. Decrease flow of oxygen
• D. Switch to a nasal cannula only

Answer: (A)

Raising the heated humidification helps because CPAP air can be dry and irritate the nasal mucosa, leading to dryness, crusting, and a feeling of congestion. Warm, moist air hydrates the passages, improves mucociliary function, and reduces irritation, making it easier for the patient to tolerate the mask and maintain a good seal. Turning off humidity would worsen dryness and congestion, not help. Decreasing the oxygen flow doesn’t address mucosal dryness and could reduce therapy effectiveness. Switching to a nasal cannula isn’t compatible with delivering CPAP pressurized air through a mask, so it won’t provide the intended therapy.
