Inpatient and home testing available.
Often referred to as the gold standard measurement of sleep, this test is used to investigate a broad range of sleep disorders including sleep apnoea, limb movement disorder, insomnia, parasomnias, and other less common sleep conditions.
The test allows physiologists to measure brain wave activity, muscle tone, limb, and eye movements, as well as the respiratory channels measured in the respiratory polygraphy/ambulatory overnight oximetry. This study involves a video recording.
At Cromwell Hospital, we offer this test as either an inpatient for a single night admission to our sleep room, or in the comfort of your own home (within a certain proximity to the hospital, available on request).
Inpatient and home testing available.
Used to diagnose central hypersomnia including narcolepsy, this test involves a single night and day admission to our sleep room.
The study involves a polysomnography followed by four to five scheduled naps performed throughout the day. The aim of the study is to get an objective measurement of sleepiness.
The polysomnography is performed to rule out many possible causes of sleepiness, and its impact, while ensuring a reasonable sleep time has been achieved.

This study involves measuring transcutaneous CO2 in conjunction with the channels involved in ambulatory overnight oximetry.
This study aims to measure breathing at night, when high CO2 levels are a potential concern. It is suggested in patients with underlying respiratory illness and/or those using non-invasive ventilation. It is also suggested in patients who are at risk of obesity hypoventilation syndrome (OHS), often in combination with obstructive sleep apnoea (OSA).
Used as a tool to diagnose sleep-disordered breathing, exemplified by obstructive sleep apnoea (OSA). It is typically administered at home.
These portable sleep study devices are collected from the Lung Centre at Cromwell Hospital and brought home with clear instructions for use. They monitor the respiratory and cardiac functions during sleep.
They are most frequently used when patients complain of snoring, excessive daytime sleepiness, or witnessed pauses in breathing (apnoea).
Used to investigate complaints of excessive sleep time, irregular sleep patterns, and excessive daytime sleepiness, actigraphy is a simple test that measures the 24-hour activity of an individual typically for 14 days.
It involves wearing a special watch, called an Actiwatch, which monitors light and activity to assess the 24-hour sleep-wake cycle.
