What is a Sleep Study?

Polysomnogram is the technical term for a sleep study. The diagnostic evaluation requires up to two overnight visits depending on the disorder. The procedure is completely painless and is performed while the patient sleeps in a private room. Up to 16 parameters of physiologic information are recorded and monitored by a sleep technician in an adjoining central control area.

Depending on the disorder, the minimum parameters we monitor include:

1. Sleep staging
    
2. Eye movements
    
3. Chin (EMG) excursion
    
4. Body position
    
5. Snoring
    
6. EKG
    
7. Leg (EMG)
    
8. Nasal/Oral airflow
    
9. Thorax excursion
    
10. Abdominal excursion
     
11. Oxygen saturation
     
12. Cpap pressure
     
13. Body Position
