What is the importance of using humidified oxygen therapy?

• A. To increase temperature
• B. To prevent dehydration of the airway
• C. To enhance the color of the oxygen
• D. To reduce the pressure of the oxygen

Answer: (B)

Using humidified oxygen therapy is crucial because it helps prevent dehydration of the airway. When oxygen is delivered without humidity, especially at high flow rates, it can dry out the mucous membranes in the respiratory tract. This dryness can lead to discomfort, irritation, and even respiratory complications, as the natural protective mechanisms of the airway can be compromised. By adding humidity to the oxygen, we ensure that the airway remains moist, which supports respiratory function and helps in the natural process of mucociliary clearance, allowing for better overall airway health. This is particularly important for patients with conditions such as chronic obstructive pulmonary disease (COPD) or those on long-term oxygen therapy, as they are at a higher risk of airway desiccation.
