Each sleep center contains private rooms and bathrooms. Most rooms have full-size temperature sensing foam beds, nightstands, lamps, and televisions.
Sleep study (Nocturnal Polysomnography or "NPSG") begins at 9PM when the patient arrives at the sleep center. The study ends at approximately 6AM.
The sleep technician applies head and body electrodes to the patient (approximate time is 40 minutes). Techician applies electrodes to the scalp with water-soluble paste, tapes electrodes to the face, and straps other electrodes across the chest and abdomen. Patient is asked to sleep shortly after electrode application.
Techician monitors the patient throughout the night. The technician wakes the patient in the morning. Patient is offered a light breakfast. Test results are returned to the referring physician within two weeks. The standard sleep study screens for various sleep disorders such as sleep disordered breathing (including sleep apnea), poor sleep architecture and efficiency, and periodic limb movements (PLM).

Titration studies also begin and end the same times as standard sleep studies. Throughout the night, a respiratory therapist slowly adjusts the therapy device until the patient's respiratory problems cease.
CPAP (Continuous Positive Airway Pressure) is a durable medical device that provides a constant flow of air into the patient's airway. The constant airflow acts as a pneumatic splint to keep the airway open and prevents the airway from collapsing (apnea). CPAP also eliminate hypopneas, when the patient's airflow decreases by 30% and causes oxygen desaturation.
BiPAP (Bilevel Positive Airway Pressure) is similar to CPAP, but provides different pressures for inspiration and expiration. The device cycles between the two pressures as the patient breaths.

Fatigue Studies (Multiple Sleep Latency Test or "MSLT") are conducted during the day and after a standard sleep study. The fatigue study involves 4 or 5 naps (20 minutes each) separated by 1.5 hours of wakefulness. The study ends between 3 and 4PM. Fatigue studies screen for narcolepsy.
