Obstructive Sleep Apnea

Diagnosis

Because treatment for OSA differs from other sleep disorders, accurate diagnosis is important. A polysomnogram is necessary to observe the nature, duration, and frequency of a given patient's breathing disturbances. Mayo Clinic in Rochester operates one of the largest, state-of-the-art sleep diagnostic facilities in the United States, fully accredited by the American Academy of Sleep Medicine.

Additional tools such as X-rays, CT scans or MRIs may also be used to better visualize anatomical structures that may be contributing to the obstruction of a patient's airway.
