Sleep Studies



Diagnosis of any sleep disorder begins with your primary care physician. He or she is a specialist in meeting the general needs of the whole patient. If further evaluation is needed on the patient for a possible sleep disorder, your primary care physician will request an overnight sleep study at West River Regional Medical Center. The study will be conducted in Hettinger by Winmar Diagnostics Sleep Wellness Center. For more information, visit Winmar Diagnostics at
