Sleep Apnoea Technology Cairns
The design and technology of our treatments
Read how home sleep studies and the treatments that are offered by Dental Sleep Medicine to treat and reduce the symptoms of sleep apnoea work.
Home sleep study
Home sleep studies involve connecting several small sensors to the patient’s head, chest and legs. These monitors record brain activity, heart rate, breathing patterns, oxygen in the blood and leg movements overnight. This data is studied at a sleep laboratory by sleep physicians and vital in prescribing the most suitable treatment options for patients suffering from sleep apnoea.
The Oventus O2Vent is a leading oral appliance and world’s first device which directs air flow through to the back of the throat using a ‘duckbill’. This allows airflow to bypass obstructions such as the soft palate, nasal and tongue. This airway device extends from the mouth like a whistle and creates a separate path for airflow.
The O2Vent is precisely made for each patient using a 3D drawing of a patient’s mouth and bite structure which is designed in CAD (computer-aided design) software based on scans and impressions of the patients mouth. The 3D printing technology processes the design, and manufacturers a bespoke, medical-grade mouthguard from durable nylon in a laboratory.
Continuous positive airway pressure (CPAP)
The CPAP was invented in 1981 by Dr Colin Sullivan who understood the benefit of a constant pressurised airflow to sleep apnoea. The CPAP machine uses a CPAP motor to create the constant airflow which is delivered to the fitted mask that covers the nose, or mouth and nose through a tube.
The CPAP motor uses a filter to take room air in, not oxygen and pressurise it according to the machine set settings that are prescribed by your doctor. This air pressure is set between 4 to 25 centimetres of water pressure (CWP) and sometimes ran by a heated humidifier before being delivered into the mask. Some CPAP machines can detect airway collapses and auto adjust the air pressure.
This constant flow of pressurised air reduces the vibrations that cause snoring and prevents the soft palate, tongue and uvula from resting and blocking the throat; ultimately preventing the airway from collapsing. This entire process helps to normalise breathing and improve sleep quality for patients suffering from sleep apnoea and other sleep conditions.
Mandibular advancement splint (MAS)
The MAS is a mouthguard that is fitted to both the lower and upper teeth. The oral appliance works by positioning the lower teeth in front of the upper teeth, as this slightly brings the lower jaw forwards which tightens the airways soft tissues and muscles. This process helps to open the airway and reduces sleep apnoea episodes during the night and lessens the severity of the episodes to promote better, deeper sleep.
