Polysomnography (Full Night Diagnostic Study)
An overnight, fully attended 12-18 channel diagnostic sleep study in which there is continuous monitoring of different sleep parameters. The parameters monitored help identify different sleep stages and diagnose different sleep disorders. Small sensors are connected to the head, face, chest and legs of the patient to monitor different brain and body activities, including brain waves, eye movements, heart rate, respiration and muscle movements.
CPAP/BIPAP Titration
A full night titration of nasal CPAP (Continuous Positive Airway Pressure) or BIPAP (Bi-level Positive Airway Pressure) after diagnosis of Obstructive Sleep Apnea has been made. This test determines the optimal CPAP or BIPAP pressure to treat the sleep apnea episodes.
Split Night Sleep Study
An overnight sleep study during which, after obstructive sleep apnea is diagnosed in the first 2 hours of the night then in second part of the night, CPAP may be initiated and titrated to determine the optimal titrating pressure.
Multiple Sleep Latency Test (MSLT)
A series of 4-5 naps performed during the day following a polysomnogram for patients with symptoms of unexplained daytime sleepiness. A MSLT is also a diagnostic study for narcolepsy.
Maintenance Wakefulness Test (MWT)
A series of 4-5 naps during the day following a polysomnogram to determine the person's ability to stay awake in a dark comfortable setting. The MWT is also used to determine if therapy for sleepiness is working or not.
Unattended Portable Limited Channel Sleep Study
An overnight unattended 4-6 channel diagnostic sleep study in the comfort of your own home. The test will primarily measure: breathing, heart rate, body position, oxygen level, and snoring.
Nocturnal Oximetry Testing
Overnight monitoring of blood oxygen and pulse rate. Used to determine oxygen needs while sleeping.
Actigraphy:
A motion detector worn on the wrist similar to a watch that detects body motion and gives indirect recording of sleep wave patterns over a period of 1-4 weeks. It is useful in diagnosing circadian rhythym disorders.
