A nocturnal polygraphy, or sleep study, is used to study the way your body functions when you sleep and to diagnose potential, sleep-related breathing disorders such as sleep apnoea, snoring, upper respiratory tract congestion, or restless leg syndrome.
During the study, your breathing, breathing movements, heart rate, sleeping position, blood oxygen level and feet movement are monitored. The study is conducted at home. You will need to place a small device with multiple sensors on your chest. The device allows you to sleep more or less normally, and you can move around freely during the study. Since a finger clip is used to measure blood oxygen level, you should not wear nail polish or artificial nails.
You should sleep as regularly as possible and avoid alcohol for a week before the study. Any prescription medication can be taken normally.
Our clinical neurophysiology specialists will provide a statement on the registered data.
