Home Sleep Testing
Cardiorespiratory Sleep Polygraph (CARP) – Level 3 Sleep Test
What is a home sleep test?
The cardiorespiratory sleep polygraph, also called home polysomnography, is an outpatient test. This means that the patient performs this test at 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 specialist. 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 Alice PDX or Alice night one devices to perform the respiratory polygraphy test. This is a small device, barely larger than a mobile phone, recommended by sleep specialists.

Respiratory polygraphy test: How does the home sleep test work?
To perform this sleep test, you will go home with the device that you will wear for 2 consecutive nights.
Once your doctor or our sleep specialist has prescribed this sleep test, you will then 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

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.
However, this home sleep test does not allow the diagnosis of other sleep-related disorders, such as restless leg syndrome, sleep behavior disorders, hypersomnolence, etc…
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.
