What this practice offers

A CPAP clinic fits the mask, sets the pressure and handles replacements. Ask about a trial of two or three mask styles, the replacement schedule your insurance covers, and what happens if the pressure feels wrong after the first week.

A general sleep clinic sees the widest mix of cases: snoring, witnessed pauses, daytime sleepiness, and insomnia that turns out to be something else. The first visit is usually a history and an examination of the airway, not a test.
