    Home Sleep Testing

    The cardiorespiratory sleep polygraphy–also called Level 3 Sleep Test or home polysomnography–is an outpatient sleep study. This means that the test is performed in the patient’s home.


    It is a simplified sleep test compared to Polysomnography. The home respiratory polygraphy (HRP) is mainly used to diagnose sleep apnea and can be prescribed by your doctor or one of our sleep specialists. It measures a few physiologic parameters that are routinely measured by polysomnography, but it can be done in the comfort of your own home.


    At Dorma, we use the WatchPAT device to perform the respiratory polygraphy test. This is a small device, barely larger than a mobile phone, prescribed by sleep specialists.

    Take a sleep test from the comfort of your home.

    A simple way to diagnose sleep disorders. Purchase your test now and have it shipped directly to your door.

    Respiratory polygraphy test: How to do a home sleep test?

    Case 1: If you do not have a prescription, contact us to make an appointment with one of our doctors who will direct you to the sleep test that best suits your condition.


    Case 2: If you already have a prescription, contact us, and we will put you in touch with the respiratory therapist. The respiratory therapist (RT) will guide you through the test, the reading, the possible results. The RT will also follow up with you after the test to interpret the results and provide your diagnosis.

    Respiratory polygraphy test: How does the home sleep test work?

    To perform this sleep test, you will bring the testing device home and wear it for two consecutive nights.

    Once your doctor or sleep specialist has prescribed this sleep test, you will meet with one of our respiratory therapists.


    The therapist will give you the equipment and information you need to do the test at home.


    You will need to wear a monitor, which is made up of various sensors that will record various physiological data throughout the night, such as:


    • Oxygen saturation and heart rate
    • Respiratory flow
    • Thoracic effort
    • Abdominal effort
    • Body position

    Getting Started With Your Home Sleep Test

    We invite you to watch the videos about the Alice PDx and NightOne, in order to better understand the way these home sleep test devices work and how to use them properly.


    A home sleep test is an outpatient (at-home) device the size of a cellphone which patients sleep with at night in their own bed. The device collects data which is used by Dorma’s sleep specialists to analyze your sleep.

    Respiratory polygraphy test: what to do after the sleep test?

    Once you have completed the respiratory polygraphy test, you will return the device to our therapists who will analyze your results and forward them to your referring doctor so that he or she can establish a diagnosis.


    The sleep test data will be analyzed and interpreted by the clinical team. The results will be sent to your doctor or the Dorma specialist who prescribed the home sleep test. He or she will be able to guide you in finding the best solution for your condition.


    This home sleep test does not allow the diagnosis of all sleep-related disorders, including restless leg syndrome, sleep behaviour disorders, or hypersomnolence.


    If your respiratory polygraphy test does not reveal any abnormalities, or if your specialist prefers to prescribe a more detailed sleep test, there is a more complete sleep test available. This laboratory/clinical test is called a Polysomnography.
