Sleep Tests and Studies
Dorma Sleep Clinic offers a range of diagnostic tests and sleep studies adapted to your needs.
Before starting any treatment, you’ll need to undergo a sleep test. This allows the sleep specialist to give you an exact diagnosis and determine the right treatment for your needs. Sleep tests must be prescribed by a doctor beforehand.
If you haven’t been prescribed a sleep test, call us to make an appointment for a free initial evaluation with one of our doctors.
If you already have a prescription, call us to book your test. A respiratory therapist will be assigned to your case and will be there to assist you every step of the way.
If you have any question, don’t hesitate to call us.
Full Polysomnography Test (PSG)
Polysomnography is an overnight sleep study in a lab. It provides the information needed for the diagnosis of multiple sleep disorders, including sleep apnea. Polysomnography is considered to be the gold standard in sleep testing.
Home Respiratory Polygraphy (HRP)
Home respiratory polygraphy, commonly known as a home sleep test, is a good alternative to polysomnography. It is a simpler sleep test and is conducted from the comfort of your home.
Nocturnal saturometry, also known as home oximetry, is performed at home. A small monitor and its sensor are placed on your finger to record your heart rate and blood oxygen saturation.
In-Clinic Manual Titration
This test is just like polysomnography (PSG) but includes an adjustable ventilator that will determine the level of air pressure needed to treat your sleep apnea. It is an in-lab test, conducted under the constant supervision of a respiratory therapist.
Iterative or Maintenance of Wakefulness Test
The iterative test, also known as the maintenance of wakefulness test, is used in both diagnosing narcolepsy and evaluating the efficiency of sleep apnea treatment. It’s an in-lab daytime test that is conducted under the constant surveillance of a respiratory therapist.
How does a Sleep Study work ?
Sleep apnea and its severity are mainly diagnosed based on the number of disturbed respiratory events during sleep.
The sleep study results will establish your apnea hypopnea index (AHI) or respiratory disturbance index (RDI) that will determine the presence and the severity of your sleep apnea.
