Cardiorespiratory polygraphy evaluates whether you have obstructive sleep apnea (upper airway blocked during sleep). It is done in your home during a full night’s sleep with a portable device from one of Biron's clinics. The device records the following physiological data:
Chest and abdominal effort
Oxygen in the blood
Cardiorespiratory polygraphy only records cardiorespiratory signals during sleep. This test is indicated for patients with multiple sleep disorder symptoms.
Specificities and Contraindications
The in-home test should not be done on a patient who is confused, unable to handle the equipment, or whose health is unstable.
Preparing for the Examination
To create the optimal conditions for a successful exam, important instructions will be sent to you when you make your appointment.
An appointment with our sleep experts
During your appointment, our respiratory therapist trained in sleep care will explain explain how the portable device works and how to do the test. You will put the device on before you go to bed and take it off in the morning. To obtain good results, you must wear the device for at least five hours. This will leave you sufficient time to do do the procedure and return the device the next day.
To help you stay motivated over the course of your treatment, we provide you with tools such as a checklist and video on how to install the equipment through our AMI web platform.
The results of the sleep test will be interpreted by one of our specialist physicians trained in sleep health and will be available via MonBiron.
A medical prescription is required to perform this examination.
