Testing includes the following:
Actigraphy is a non-invasive method of monitoring human rest/activity cycles. A small actigraph unit, also called an ac- timetry sensor, is worn for a week or more to measure gross motor activity. The unit is usually a wrist-watch-like package worn on the wrist.
ASV Titration Study
Adaptive Servo Ventilation (ASV) is a non-invasive ventilatory treatment option created specifically for the treatment of adults who have obstructive sleep apnea and central and/or complex sleep apnea. Many times this would be the third sleep study done, which is unusual. However, certain apnea (central/complex) does not respond to CPAP or BiLevel. Because of this, CPAP and BiLevel must be ruled out before proceeding with ASV.
BILEVEL titration study
A BILEVEL titration study is a type of in-lab sleep study used to calibrate continuous positive airway pressure therapy. A BiPAP (Bilevel Positive Airway Pressure) machine is more complex than a CPAP. It delivers pressured air at a higher pressure while inhaling, and a lower pressure while exhaling.
CPAP Titration Study
A CPAP titration study is a sleep study done at our Sleep Center which calibrates continuous positive airway pressure (CPAP) therapy. CPAP is a common treatment used to manage sleep-related breathing disorders including obstructive sleep apnea, central sleep apnea, hypopnea, hypoventilation, and hypoxemia. It is the follow up to a “positive” Polysomnograph (PSG) test.
Home Sleep Study
In order to diagnose Sleep Apnea or other sleep disorders, a patient will undergo a Polysomnography test (PSG). This is a test which electronically transmits and records specific physical activities while asleep. This test is required to be done at our Sleep Center. However, with today’s technology in certain situations, this polysomnography can be performed in a patient’s home and is called a Home Sleep Study, or Home Sleep Test.
Multiple Sleep Latency Test (MSLT)
The MSLT is a full-day test that consists of five scheduled naps separated by two-hour breaks during which time you cannot sleep or nap. During each nap trial, you will lie quietly in bed and try to go to sleep. Once the lights go off, the test will measure how long it takes for you to fall asleep. You will be awakened after sleeping 15 minutes. If you do not fall asleep within 20 minutes, the nap trial will end. This test takes place after an overnight Polysomnogram at our Sleep Center.
A sleep study or “PSG” is a painless test that electronically transmits and records your specific physical activities while you sleep. Your sleep will be monitored remotely by a Registered Polysomnogram Technologist.
Split Night Study
A split–night study is an overnight polysomnogram performed with at least a two-hour period of baseline sleep study recording, followed by a CPAP titration study. The CPAP portion is only performed if there is clinically significant sleep apnea, which is over 5 events in an hour.
