Somnofluoroscopy.
In the past 30 years, numerous studies have increased our knowledge of the physical process of sleep. One sleep disorder, sleep apnea, has been studied and found to be a serious and life-threatening condition. Diagnosis of sleep disorders is very difficult and requires the use of sophisticated equipment, highly trained personnel, and a unique environment. To confirm the most dangerous form of sleep apnea, obstructive sleep apnea, fluoroscopic evaluation of the upper airway during sleep was performed. This fluoroscopic evaluation of the upper airway during sleep has been termed "somnofluoroscopy."
