Sleep Apnoea

Sleep apnoea is a condition where you pause breathing for periods that can extend to a few minutes in the night.  It affects roughly 1 in 10 of us. These pauses can reoccur many times a night.

As a result you are not refreshed by your sleep and you can be very tired when you wake up.  This is very dangerous and may be linked to an increased risk of a traffic accident.

We are exploring how Continuous positive airway pressure (CPAP) machines improve the symptoms of sleep apnoea. We are trying to monitor how changes in your blood could indicate if CPAP is working and how its use can be improved.
