Manual Titration of Positive Airway Pressure by Polysomnography
In the laboratory
What is a manual titration of positive airway pressure by polysomnography?
This is a test carried out at Biron once a diagnosis of sleep apnea has been made. Using a CPAP device, the test allows you to manually and gradually determine the optimal level of pressure required to counter the obstructions in the airways and thus control your sleep apnea.
Biron’s healthcare professionals trained in sleep care will accompany you throughout the examination process. They will ensure your comfort and wellbeing.
Here are some guidelines to follow in order to be well prepared on the day of the exam:
You may eat a normal meal before 7:00 pm. However, we ask that you refrain from consuming alcohol (e.g. beer, wine) or caffeine (e.g. coffee, tea, cola, chocolate) in the 6 hours before the test
Please avoid using face cream or body lotion
You may bring comfortable sleep wear and your own pillow. We provide towels, soap and shampoo, but you may also bring your own toiletries.
If necessary, remember to bring your usual medications.
A manual titration of positive airway pressure (PAP) by polysomnography is risk-free and causes no pain. In rare cases, you may experience temporary skin irritation where sensors were applied to your skin.
The following is the typical process for a polysomnography at one of Biron's clinics.
The normal arrival time is between 8:30 and 9:00 pm (please be on time for your appointment). Depending on the time of your appointment and the preparation time, your bedtime may vary between 9:30 and 11:30 pm.
When you arrive at the clinic, a healthcare professional will welcome you, show you your private bedroom (with bathroom) and explain the examination procedure. Your bedroom will be dark and quiet so you can relax and fall asleep. It is equipped with an audiovisual system for diagnostic purposes and to ensure your safety. Your sleep will be observed throughout the night by a healthcare professional trained in sleep care, who will monitor proper recording of the data as well as your wellbeing at all times.
Before your bed time, several painless sensors will be applied to your scalp, temples, hands, chest and legs. These record:
Electrical brain activity
Blood oxygen level
You may rise between 6:00 and 6:15 am and take a shower at the clinic.
Specificities and Contraindications
Please note that the manuel titration cannot be performed on a patient with low blood pressure, who is confused or who cannot cooperate fully during the examination.
Your examination results will be interpreted by one of our medical specialists trained in sleep care.
Depending on the method you choose either through the result portal or by post office, your test results will be sent to you and the requesting health care professional within 10 to 15 business days.
A medical prescription is required to perform this examination.
