Sleep observation: An overnight recording of a persons sleep including sleep stages, time awake vs. Asleep, oxygen saturation, blood pressure, breathing effort, snoring, arousals and leg movements. Conducted in a sleep center is considered an attended study and at home it is considered an unattended study. At home studies do not record as much information as an attended study in a sleep center.
