Obstructive sleep apnoea (OSA) is a very common condition affecting 2-4% of adults to a significant degree. It characterised by repeated episodes of obstruction of the throat during sleep and is usually associated with loud snoring and excessive daytime sleepiness.
OSA is an independent risk factor for the development of hypertension and insulin resistance, and is associated with heart attack, cardiac arrhythmia, and stroke.
Treatment includes lifestyle changes, Continuous Positive Airway Pressure (CPAP), Mandibular Advancement Splint (MAS), Provent and surgery.
A sleep study may be performed to assess many different issues relating to sleep. This can include but is not limited to:

What’s involved?
An overnight diagnostic sleep investigation is a painless, non-invasive procedure that uses the latest technology in sleep monitoring systems to record numerous physiological signals which include:
Diagnostic Sleep Study Options
CPAP Sleep
StudyContinuous Positive Airway Pressure (CPAP), pronounced see-pap, is the gold standard method in the treatment of obstructive sleep apnea in adults. It involves splinting the upper airway and preventing the collapse of these structures, while also abolishing snoring.
To achieve this, the CPAP unit will deliver a continuous, low pressure to the upper airway via a nasal and/or mouth mask. While using this therapy, no additional oxygen is delivered, the pressure is generated solely from filtered room air.
This study involves a Continuous Positive Airway Pressure (CPAP) flow generator which generates the required pressure to keep the upper airways open during sleep. The air pressure is delivered through the application of a CPAP mask by Sleep Scientists & Nurses. The CPAP study is used to determine the appropriate pressure settings to treat Obstructive Sleep Apnoea (OSA) and snoring.
There is a very large range of masks available at all sites so we can optimise comfort and fit for your study.
CPAP Sleep Study Options
Mandibular Advancement Splint
Mandibular Advancements Splints (MAS) may be used in the treatment of mild to moderate Obstructive Sleep Apnoea (OSA) and simple snoring.
MAS devices can best be described as two small football mouthguards, one fitting on the upper teeth and one on the lower teeth.
The two sections are joined with the bottom section brought forward a pre-determined amount to improve the function of the upper airway and other structures implicated in OSA and snoring.
Essentially there are two types of MAS devices. Fixed or block splints are attached near the back teeth and do not allow lateral (side-to-side) or vertical movement. The second type consist of a separate upper and lower plate (2 piece units), with a sliding mechanism located near the back teeth, which allows mouth opening and lateral movement.
Provent
rovent is a device used in the treatment of sleep apnoea and snoring. Provent consists of a small valve attached externally to each nostril with hypoallergenic adhesive designed for single-night use.
The valve acts as a one-way resistor, allowing air to flow freely when breathing in. When breathing out, the airflow is directed through small air channels, increasing the resistance. This increased resistance when breathing out creates a pressure which helps keep the upper airways open during this phase of breathing.
Provent is a disposable device which is worn during sleep and removed each morning.
Below are some risk factors that may be associated with having untreated sleep apnoea.
Risk factors of untreated sleep apnoea include:
