A patient who will begin oxygen therapy has a history of sinus disorders. This patient would benefit most from which oxygen setup?
Explanation & Rationale
A. A venturi mask: The Venturi mask is often used in patients with COPD. However, it may cause dryness and irritation in the nasal passages and sinuses due to non-humidified, high-flow delivery, which could aggravate existing sinus conditions. B. A nasal cannula: While nasal cannulas are less drying than masks and suitable for low-flow oxygen delivery, they can still cause mucosal dryness when used without humidification, particularly in patients with sinus issues. C. High-flow oxygen via nasal cannula: High-flow nasal cannula therapy provides warmed, humidified oxygen, but at higher rates than needed for most patients starting oxygen therapy. It is more appropriate for acute respiratory failure than for routine use in sinus conditions. D. Adding humidification to the oxygen setup: Humidifying oxygen helps prevent nasal and sinus mucosal dryness and irritation, making it beneficial for patients with sinus disorders. Moisture improves comfort and protects the integrity of the upper airway mucosa during oxygen therapy.
