An EEG analyzes your sleep phases and the cycles of REM and nonREM or NREM sleep you go through throughout the night to uncover any abnormalities in your sleep pattern. A sleep study will also record your eye movements, oxygen levels in your blood (through a sensor—no needles are used), heart and breathing rates, snoring, and body movements.
The data from your sleep study will typically be collected by a technician and analyzed by your doctor.
