Which statement about orofacial masks is accurate?

• A. They never leak air
• B. They cover both the nose and the mouth
• C. They are never used in sleep studies
• D. They cover only the mouth

Answer: (B)

Orofacial masks are full-face interfaces used with positive airway pressure devices in sleep medicine. They are designed to seal over both the nose and the mouth, which helps deliver the prescribed pressure even if you breathe through your mouth or have nasal congestion. The mask isn’t inherently leak-free; air can escape around the edges if the fit isn’t right, so proper sizing and fit are essential. These masks are commonly used during sleep studies and PAP titration when a nasal-only mask wouldn’t provide a reliable seal or comfort. They don’t cover only the mouth, and they aren’t never used in sleep studies.
