Why is it important to use a heated humidifier with NIV?

Using a heated humidifier with noninvasive ventilation (NIV) is essential for several reasons, primarily related to patient comfort and respiratory health. When air is delivered through a ventilator, it is typically dry and can lead to airway irritation, drying out the mucous membranes of the upper and lower respiratory tracts. This can cause discomfort for the patient, increase the risk of airway inflammation, and potentially lead to complications such as mucus plugging, which can severely impede breathing.

The heated humidifier adds warmth and moisture to the air being delivered, mitigating these risks. This promotes optimal airway patency, enhances mucociliary function, and ensures that the airway remains comfortable, which can significantly improve the overall tolerance of the patient to NIV. Thus, the use of a heated humidifier is critical for not only enhancing comfort but also for preventing potential airway complications associated with dry air delivery.
