What is a common issue patients may face when using a full face mask?

Patients using a full face mask during noninvasive mechanical ventilation often encounter challenges with secretion clearance. The design of these masks covers both the mouth and nose, which can create a barrier and make it more difficult for patients to effectively cough or clear secretions. This is particularly significant for individuals who may already be experiencing respiratory issues. The mask can also contribute to discomfort, leading to anxiety or a reduced ability to coordinate coughing, further complicating the clearance of mucus and other secretions.

In contrast, heightened communication abilities, facilitated eating, and improved facial mobility are generally not advantages offered by full face masks. The full coverage of the face can actually hinder communication since patients cannot easily talk. Eating while using such a mask is impractical and often not feasible due to the mask's obstruction. Additionally, it may restrict facial movements compared to other types of masks, which could theoretically allow for greater mobility of the jaw and mouth.
