When you visit our service point, we will give you the case containing the accessories needed to perform the test. You will also find detailed explanatory sheets to help you install the equipment. You will also have access to an explanatory video that will guide you step by step through the installation of the equipment. 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.

At your appointment, you will receive a carrying case containing all the materials and instructions needed to install the equipment. In addition, a video will guide you step by step during the installation.

The longer you wear the device, the more the recorded data will allow a representative diagnosis. It is recommended that you wear the device for at least five hours.

Following your diagnosis, you will have a personalized meeting with a respiratory therapist. This meeting will complete the assessment of the signs and symptoms associated with your sleep disorder.
