What Is Polysomnography

Polysomnography is an overnight test that records multiple body functions during sleep including brain waves eye movements heart rhythm oxygen levels breathing effort airflow and limb movements It helps diagnose sleep apnoea periodic limb movement disorder narcolepsy and other sleep related conditions that disrupt rest and lead to daytime fatigue

Who Should Have a Sleep Study

Doctors recommend polysomnography for people who snore loudly with observed breathing pauses wake up choking or gasping feel unrefreshed despite a full night in bed fall asleep easily during the day or have unusual behaviours such as kicking talking or acting out dreams Recurrent headaches on waking poor concentration and uncontrolled high blood pressure can also be linked to sleep disordered breathing which is confirmed or excluded by a formal study

How the Test Is Done

On the night of the study the person checks into a quiet sleep laboratory room that resembles a regular bedroom but is equipped with monitoring devices Trained staff attach sensors to the scalp face chest limbs and finger to record the required signals and then leave the patient to sleep while observing from a control room A camera records body movements while computers store the signals for later analysis by a sleep specialist

What Polysomnography Measures

The test records sleep stages using EEG eye movements and muscle tone tracks heart rate and rhythm monitors airflow at the nose and mouth and measures breathing effort from the chest and abdomen Pulse oximetry shows oxygen saturation while sensors on the legs detect periodic limb movements Together these data allow detection of obstructive and central apnoeas hypopnoeas arousals and abnormal behaviours during different sleep stages

Results and Treatment Planning

After the study a sleep specialist reviews the entire night recording calculates indices such as apnoea hypopnoea index and oxygen desaturation levels and correlates them with symptoms For obstructive sleep apnoea treatments may include weight management positional therapy dental devices or continuous positive airway pressure therapy For limb movement or narcolepsy syndromes medicines and behavioural strategies are tailored accordingly Early diagnosis and treatment can markedly improve daytime alertness blood pressure control and overall cardiovascular risk
