All patients require an overnight sleep study to determine if they have obstructive sleep apnoea syndrome (OSAS). You do not need to stay in hospital overnight – our sleep unit offers a home sleep study service.
The patient will need to attend the sleep diagnostics clinic at the Lister. They will have some routine tests and then they will have the sleep study equipment demonstrated by our staff. The study can then be done in the patient’s home and be returned the next morning.
Overnight Sa02 (oximetry) monitoring
This is a small device which attaches to the wrist and has one finger probe. It measures the oxygen levels in the blood and pulse rate throughout the night.
Domiciliary multi-channel sleep study
This is a more complex machine requiring the patient to wear five or six different leads. This includes belts round the chest and abdomen, a finger probe, leg probe and airway/snoring sensor.
These monitors resemble a watch and are worn on the wrist. They are fully waterproof, so they can be worn all the time. They monitor activity over a period of a few days or weeks, helping the clinicians to assess sleep/wake cycles, insomnia and other sleep rhythm disorders.
A soft mask is attached to the CPAP machine that blows air through the nose or nose and mouth into the air passages to stop it collapsing during the night.
There is no overnight stay for a trial of CPAP. All patients have a two-hour appointment that involves:
- A group teaching session,
- Individual expert mask fitting
- Demonstration of the CPAP machine and
- A chance to sleep/relax on a bed with the equipment to ensure the best possible outcome.
All patients are followed up on a regular basis and provided with a maintenance and replacement service for the equipment.
The MAS is an oral device which keeps the lower jaw in a forward position during sleep which widens the upper airway reducing an obstruction. The maxillo-facial team would assess and be responsible for the fitting of MAS. This can have great outcomes for people with mild obstructive sleep apnoea syndrome (OSAS).
