Among the NIV interfaces, which one is generally tolerated the best by patients?

The nasal mask is generally tolerated the best by patients using noninvasive ventilation (NIV) due to several factors that enhance comfort and usability. This interface covers only the nose, which often allows for more natural oral communication and reduces the feeling of claustrophobia that can be associated with full face masks.

Additionally, the nasal mask has a lower profile and is typically less cumbersome than others, making it easier for patients to perform daily activities like eating or drinking while receiving therapy. The design allows for a better fit for many patients, resulting in improved seal and ventilation efficiency without excessive pressure or discomfort.

In contrast, the full face mask can lead to a feeling of confinement and may be more prone to leaks because it covers a larger area, including the mouth. Nasal pillows, while offering another comfortable alternative, can be poorly tolerated by some patients who may find them less secure or worry about their fit. The oral mask is less commonly used and is not optimal for NIV since it does not effectively cover the nasal passages, which are critical for patients requiring respiratory support.

In summary, the nasal mask strikes a balance between comfort, tolerance, and effectiveness, making it the preferred choice among various NIV interfaces.
